Brain Teasers Posted by mad-ade 04/11/02 you cannot score 0 on a dart board, unless you miss and then it isn't clased as a score. There fore the lowest number you can't get with three valid darts is one, because if each dart is valid then the minimum score possible is three. if the dart misses then it isnt valid. Posted by cathalmccabe 04/12/02 OK I don't play darts, but if you throw one dart, get one, and miss with the other two darts do they let you take them again? I submitted this puzzle for maths, not logic so as far as I can see, 0 can be "scored" 1 can be scored with 3 darts etc all the way up Posted by mad-ade 04/12/02 if you throw three darts at a board, and two miss, then you have only "used" one dart to make a score not three.

it is impossible to score 1 with three darts, the two that missed don't really count, because in reality you could just drop them on the floor, and claim that you have used three darts. using a standard dart board only darts that land in a designated scoring segment count as valid darts. there is no such scoring segment that scores 0. for the darts to count they have to land in the segments. if you throw three dart and only one lands in a scoring segment, then you have only scored using one dart, not three. Posted by lessthanjake789 09/26/06 to answer the annoying "3 darts" question - if you miss the board completely, then fine, that doesnt count... but if you hit the board, just not inside the numbered part (so, that little inch or so strip along the edge), its a valid throw resulting in 0 Posted by lessthanjake789 09/26/06 Now, as for what numbers you cannot get... consider 23 the last important number because that is the first prime number not on the board (therefore unattainable).

23 on top of 120 does make 143 the SEEMINGLY lowest number, assuming the other 2 are as high as possible. However, as has been noted repeatedly, there are other combinations because you CAN score higher than 23. So this opens up a world of possibilities... and restrictions, too, i think. I will work on it and come back though, not enough time now. Posted by lessthanjake789 09/26/06 The list of numbers between 0 and 60 not possible on a dart board are as follows - 23, 25, 29, 31, 35, 37, 41, 43, 44, 46, 47, 49, 50, 52, 53, 55, 56, 58, 59. Obviously the HIGHEST number unattainable would be 179 (obviously with 180 as the ceiling, as its the highest possible). Combinations of additions must be taken into account for other numbers, though.

Again, ill be back when i have more time Posted by lessthanjake789 09/26/06 hahaha. I had to reread that comment about 7 times cause it said i had curse words in there.... i finally realized i transposed a C and the O in account. anyways Posted by Jimbo 04/26/09 I have googled the rules for darts and as far as I can see, if I am playing an opponent and they throw three darts that miss the board, then their score is zero? What else could you write down? They don't get to take the throws again! I don't get the objections. :cry: Posted by markescali 10/27/11 Ok,Considering S[1-10],D[2-40],T[3-60],outRing25 and bEye50...the score will be between min4 and max 170. With a program.... an impossible one is 163... not sure its the lowest.... any numbers ... just to test my program?

;) Search: Lowest score impossible to get with 3 darts., page 1 Lowest score impossible to get with 3 darts. page: 1 link On a regular dartboard, with 3 throws. What is the lowest possible score you can't hit. Disregard the rules that you have to throw out with a double. I got the answer by trying, but I want to know if theres a elegant way of getting the right answer. Um, wouldn't that be "1"? It's the lowest score, and you can't hit (to) it in three darts... Maybe you mean highest possible score... hmm, I'm thinking 301 - 141 = 160. You start at 301, right? reply to post by BcnDiamond if a dart must hit the scoring section the answers 3, if it just has to hit the board, the answer is 0, so lowest score you can('t) hit would be 0 i guess. [edit on 23/1/09 by pieman] Good question, would be interesting to know. 172, i would guess.

reply to post by BcnDiamond if a dart must hit the scoring section the answers 3, if it just has to hit the board, the answer is 0, so lowest score you can('t) hit would be 0 i guess. [edit on 23/1/09 by pieman] He means with 3 scoring darts what is the least you cannot score. Any combination of 3 scoring darts, what is the lowest you cannot get. oh right, i get ya, triple 20 is the highest scoring slot so 180 is the highest score on three darts, that'll leave 121 if you're playing 301 and 321 if you're playing 501. EDIT: hang on, nope, still don't think i get it. cannot get, what?!? [edit on 23/1/09 by pieman] 301 - 3*20 - 3*20 - 9 = 172 So a triple 20, another triple 20, and a nine would give you 172, so that is a possible score with three darts...

LOL , what i mean is: You start from zero, then throw three darts, which must hit. What is then the lowest possible score you can't hit. The answer will come to you, if you calculate a couple possibilities, but really im looking for a simple explanation or formula for the correct answer. 301 - 3*20 - 3*20 - 9 = 172 So a triple 20, another triple 20, and a nine would give you 172, so that is a possible score with three darts... You have misread the question. He is asking what is the lowest number you cannot score with 3 scoring darts. I think it is 172, as you cannot get that with 3 darts. If you guys can find a lower number than good luck to anyone. LOL , what i mean is: You start from zero, then throw three darts, which must hit. What is then the lowest possible score you can't hit. The answer will come to you, if you calculate a couple possibilities, but really im looking for a simple explanation or formula for the correct answer.

So is there a number lower than 172 that you can get? have you worked out the answer? LOL , what i mean is: You start from zero, then throw three darts, which must hit. What is then the lowest possible score you can't hit. The answer will come to you, if you calculate a couple possibilities, but really im looking for a simple explanation or formula for the correct answer. So is there a number lower than 172 that you can get? have you worked out the answer? Yes there is, but your talking about numbers here and certain possibilities there must be a formula or something to calculate the answer. Ill give you a few thoughts before giving the answer. I think the answer is the sum of dart 1 maximum score dart 3 first impossible score to hit with one dart (or in different order) I dont think there is a formula for the first impossible score with one dart, you just have to go threw all the possibilities [edit on 23-1-2009 by Just-Think] Consider the points you could make, with three darts.

You can get 0-5 points by missing the first two darts: miss, miss, miss = 0 miss, miss, four = 4 miss, miss, five = 5 Then, you can get 6-11 points by hitting two triple 1's, and another miss or 1-5: triple 1, triple 1, miss = 6 triple 1, triple 1, one = 7 triple 1, triple 1, two = 8 triple 1, triple 1, three = 9 triple 1, triple 1, four = 10 triple 1, triple 1, five = 11 That pattern repeats: two triple 2's plus another dart give 12-17: triple 2, triple 2, miss = 12 triple 2, triple 2, one = 13 triple 2, triple 2, two = 14 triple 2, triple 2, three = 15 triple 2, triple 2, four = 16 triple 2, triple 2, five = 17 Allowing all possible scores, all the way though two triple 20's

: triple 20, triple 20, miss = 120 triple 20, triple 20, one = 121 triple 20, triple 20, two = 122 triple 20, triple 20, three = 123 triple 20, triple 20, four = 124 triple 20, triple 20, five = 125 ...

triple 20, triple 20, single 20 = 140 Then, you have to look at non-singles for the third dart: triple 20, triple 20, 21 (triple 7) = 141 triple 20, triple 20, 22 (double 11) = 142 triple 20, triple 20, 23 is prime, however - so 143 can't be hit! 301 - 143 = 158 A geek plays darts Advertisment A geek plays darts Darts is a very common English pastime. It involves the hand launching of sharp projectiles at a wall-mounted target from a distance of approximately 8 feet. The circular target (dart board) is divided into twenty radial segments with basic point values ranging from 1 to 20 points. In addition, there are two narrow annular rings, one at the edge of the board (the "double"); a dart landing in this region scores double the segment value, and a "triple" ring which runs around the middle of the segments (scoring three times the basic segment value).

Finally, at the center of the board are two scoring regions (the "Bullseye"). The very center "inner bull" scoring 50 points, and the ring outside the "outer bull" scoring 25. The image to the left is picture of a regulation dartboard, as created by Brian Gamlin in 1896. As you can see, the numbers are arranged in a pattern designed to penalize inaccuracy, with high scoring segments placed adjacent to lower scoring regions. Highest Score It doesn�t take a mathematician to calculate that the highest score achievable with a single dart is 60 points. This is achieved be successfully hitting the triple 20. This, however, is not as easy as it sounds. The triple 20 comprises an area of just 259 mm2 (that�s 4/10ths of a square inch for my metrically challenged readers). In percentage terms, this represents less than 0.9% of the scoring region of the dart board. Hitting the triple 20 consistently takes a considerable amount of skill (after all, this is the equivalent of hitting an area less than the size of a postage stamp from eight feet away).

Even professional players are not able to hit this region all the time, and the point penalty for inaccuracy can be severe with the low scoring regions of 5 and 1 being immediately on either side. Where to aim Where is the best place for a player to aim, knowing the inaccuracies of throwing? What is the optimal strategy? Where should a player aim in order to obtain the highest expected outcome over many throws? Should they aim for the triple 20, with a big payout on a success, but a low score from a miss? Or, should they aim for the bullseye? Alternatively, is there some other optimal location on the board they can aim for that, whilst not the highest scoring region, has a large exapnse of middle of the road point values. Would aiming for this region, even with an inaccurate shot, get a reasonable number of points such that, on average, the expected score is the highest that can be achieved? The true answer to this riddle, as we will see, is that "it depends…" The optimal strategy for aiming depends on your skill as darts player.

A very skillful player should aim for the middle of the triple 20; Much of the time he will hit his target, and the times he misses will be few enough that his average score will still be high. A very poor player should aim close to the bullseye, as just hitting the board will be an achievement (and a scoring one at that!). Aiming for the center maximizes the chances of hitting something. But what happens between these two extreme? Normal Distribution I�m going to model a dart throw by assuming a player aims at an objective, and their accuracy of hitting this objective is distributed according to a Gaussian distribution function. I�ll spare the math, but sufficient to say there is a probability density function which is shaped like a �bell� and this shape describes the probability that a dart will land in this location. It�s highest at the objective (the center), and falls off symmetrically the further away from the objective travelled. (You may have also heard this distribution called a �Normal Distribution�).

An elegant stochastic mathematical formula describes the shape of the curve; we�ll use this formula to represent the probability that the dart will land that far away from the objective (The area under the curve is 1.0; the dart has to land somewhere!). One of the parameters of the function is something called the Standard Deviation, represented by the small Greek letter Sigma σ. Standard Deviation (σ) Again there�s a lot of math related to standard deviation, but the easiest way to think about σ is that it�s a measure of the �average deviation around the average�. If you are a good darts player, you will have a low standard deviation, and your shots will be closely clustered around their intended objective. A medium skilled darts player will have a larger standard deviation; even though the shots may, on average, be centered around the same target, they will be distributed over a broader region. A poor darts player will have a high standard deviation and their shots will be, probabilistically, scattered over a much wider region.

Superposition Now that we have a curve to describe the probability of a where a dart will land based on a target and standard deviation, we can sweep this curve over the board and calculate the expected score for each possibly aiming location. (Because of the stochastic nature of the probability distribution function, we simple multiply the probability of the dart landing at a certain location by the point scored at that location, then integrating this for the entire board). The result is something like this, which is a plot for σ=17 mm Colour is used to represent the expected score. There is a legend on the right giving the scale. The optimal location to aim (the highest achievable expected score) is represented by the magenta reticle. It's value and coordinates are described in the lower left corner. For this value of standard deviation, the higest expeceted score is 19.757 which is obtained by aiming just inside the triple 19 segment. (The coordinates for this location are represented in Polar format as a radius measured from the center of the board in mm, and an angle, measured from 12'o'clock, in degrees). Results from a range of σ Here are some results for a selection of increasing σ.

By definition, with a σ=0 mm there is no variance in the shot, and every dart lands perfectly on target. The maximum expected score for σ=0 mm is 60, and this can be achieved by aiming anywhere inside the triple 20 segment. (Click on any of the images below for a Hi-Res version.) With σ=1 mm the deviance is very small, and just about all shots taken hit their intended target. The maximum expected score is 59.995. With this low σ, the tail of the curve falls off so rapidly such that, even with double floating point precission, there are a range of coordinates that all achieve this same expected outcome. This is show as the Magenta bar on the above picture. Increasing the σ to 5 mm creates a slight 'bloom' around each of the segments, and whilst the maximum expected score has lowered to 42.939, the aiming location is still centered in the middle of the triple 20.

By the time that σ has increased to 10 mm, the maximum expected score has decreased to 29.457 The Gaussian blur around the triple 20 is skewed slightly to the left (closer to the 5 segment on the left than the 1 segment on the right) – if you are going to drift horizontally, you'll achieve a slightly higher score by going that way. You can see the angle has changed to 359.4° At σ=15 mm, this left drift continues (and the optimal location moves outwards slightly so that the probable circular distribution pattern, if it falls outside the 20 segment, is more likely to land in the triple 5 location than just the vanilla 5 area). The maximum expected score is now 21.705 As we saw from the first σ=17 mm image, the maximum scoring location jumps from the triple 20 region to the triple 19 region (It makes this transition just before σ=16�mm). The above image is the pattern for σ=20 mm. Interestingly, at this time, the optimal aiming point is just outside the triple 19 ring.

At σ=25 mm, it's still just outside, and the maximum expected score is down to 15.796 At σ=30 mm, the optimal aiming position has moved inside the triple 19, as it starts its migration up and around (more on this later …) At σ=85 mm, as predicted, it's moved close to the bullseye, where it stays from this point onwards. NOTE– Each of the above images was normalised onto it's own private colour range. Movie Here is a short animation showing the change in probability distribition with the change in σ from 1mm to 100mm in 1mm increments. Somethings look even better in 3D Geeking out, here are some plots of the probability functions in 3D. Click on each image to view it in full resolution. σ=2 mm With a very low σ, each scoring segment looks like a tower with (almost) the height of the scoring region, and Gaussian blurred edges. The highest 'peak' is the triple 20. σ=16 mm As σ increases, the towers spread out and diffuse into each other.

At this level of σ the maximum value is still in the triple 20 region. σ=30 mm The hills have now spread out much further and become lower and broader. The highest value is now close to triple 19. σ=50 mm Now it's no longer possible to identify the individual peaks, and a much flatter plateau develops. Migration of the optimal aiming point Here's a plot of how the maximum expected value peak migrates around the board with increasing σ. For low values of σ it is in the triple 20 region. It jumps to the triple 19 region, then curls and moves around the lower left region of the board until ending up just inside the inner bullseye for incredibly large values of σ. Decline in score As accuracy decreases and σ increases, the highest achievable expected scores also falls. Here is a plot of the highest expected score against σ. With medium to high values of σ the expected score is between 10 and 15 points, but as σ is reduced there is a sharp elbow in the curve, and highest expected score increases rapidy. This elbow occurs around σ=20 mm.

Players with values of σ higher than this elbow value will obtain poor scores at darts, whilst those with better accuracy (smaller σ) will achieve much higher scores. The difference in gradients either side of this eblow value is so severe that if two players, one either side of this threshold, play it's pretty much game over for the less accurate player. Darts is a game in which the difference between a mediocre player and a good player manifests itself so savagely that it will be a very one-sided game if two players of different skills play. As σ increases further, there is a second eblow in the curve. This happens because the probabily density cloud starts to become so large that there is a good chance that a thrown dart will miss the board completely! A missed dart does not score, and reduces the expected value. As σ increases, the maximum expected value asymptotes to zero. Below is a plot of larger values of σ against maximum expected score. In this graph, the x-axis, showing σ is plotted in log scale. Estimating your σ How would you go about estimating your σ?

Using a cummulative version of the probability density function, it's possible to calculate the probability of hitting within a certain radius (the shaded region in the image below) based on a value of σ. Low values of σ have a very tall and narrow peak so that a high percentage of the area under the curve will be within a certain radius. As σ increases, the curves get broader and shallower and a increasingly smaller region of the curve will be under the same two bounds. Throw 50 darts at the bullseye and count the number of darts that land within the outer bull. Then look up this number on the table to the right and read off the corresponding value for σ Hits 43 mm Are you a good darts player? Remember back to the elbow on the maximum expected results chart which occured around σ=20 mm? Reading this on the table above, this corresponds to approximately 23/50 hits on the bullseye. So, if can aim at the bullseye of a dart board, and can consistently get half your darts inside the outer bull of the board, then you are on the steep part of the scoring and probably a hard player for an amateur to beat!

ï¿½ OFFICIAL SKILL RATING PROCEDURE Points Per Dart (PPD) and Marks Per Round (MPR) are the official means of classifying and ranking players. PPD:ï¿½ï¿½ï¿½ Points Per Dart is used for all ï¿½01 games, (301, 501, etc.).ï¿½ To obtain a PPD, divide the total points by the number of actual darts thrown.ï¿½ Example:ï¿½ Player #1 wins the game with his 12th dart.ï¿½ He has achieved a total of 301 points.ï¿½ His PPD is 25.08 (301 / 12 = 25.08).ï¿½ The winner of the game will use the total points of the game, (301, 501, etc.) all other players will use the actual points scored as reported by the machine.

MPR:ï¿½ï¿½ï¿½ Marks Per Round is used for all Cricket games.ï¿½ To obtain a MPR, divide the total number marks scored by the actual number of darts thrown then multiply by three (3).ï¿½ Example:ï¿½ Player #1 wins the game with their 46th dart.ï¿½ They have achieved a total of 59 marks.ï¿½ Their MPR is 3.85 (59 / 46 x 3 = 3.85). JUST DARTS LEAGUE PLAYER RANKINGS ï¿½ Just Darts will re-evaluate player rankings after every league season. ï¿½ A new unranked player must complete a minimum of 24 league games to establish a skill ranking. ï¿½ Player known ability will also rank players. ï¿½ Players that represent two different PPD and MPR divisions will be ranked with the higher stat.

SANDBAGGING ï¿½ï¿½Sandbaggingï¿½ ï¿½ The intentional distorting of rating stats either via the throwing or the recording of darts. If a player misses his out, is that ï¿½sandbaggingï¿½?

Not necessarily.ï¿½ It may be a momentary response to a competitive situation.ï¿½ It may be the reflection of dedication and practice.ï¿½ It may be a high point in the normal fluctuations (hot and cold) that are part of a playerï¿½s rating. However, if there is a consistent pattern to a player scoring higher in non-stat games, matches and/or events said player scores when stats are being recorded; it is sandbagging! ï¿½Sandbaggingï¿½ is winning outside the defined, established, and accepted ethics and rules of the sport. ï¿½Sandbaggingï¿½ is receiving prize money that rightfully belongs to others. Solution ï¿½ Just Darts cannot solve sandbagging. ï¿½Sandbaggingï¿½ will only be minimized (never totally eliminated) through the combined efforts of the players, the location owners, the Executive Board and Just Darts. Players: ï¿½ Do not shoot with ï¿½sandbaggersï¿½ in leagues and/or tournaments. ï¿½ Assist your location in identifying in-house sandbaggers.

ï¿½ Provide Just Darts and the Executive Board with the objective information needed to enforce the ï¿½sandbaggingï¿½ policy. Location Owners: ï¿½ Exclude ï¿½sandbaggersï¿½ from your dart program. ï¿½ Alert Just Darts of your in-house ï¿½sandbaggersï¿½. ï¿½ Recognize your responsibility to all the players in the league.ï¿½ Tolerating ï¿½sandbaggersï¿½ is an inequity to every one of your legitimate, honorable players. Just Darts: ï¿½ Be willing to decline teams from locations that promote, tolerate, and/or ignore ï¿½sandbaggersï¿½ within their operations.ï¿½ ï¿½Sandbaggingï¿½ will be reviewed and disciplined on an individual basis by the Executive Board. A continuing program presence of ï¿½sandbaggersï¿½ within a location will cause said location to be excluded from the Just Darts Leagues. It will not be tolerated for a player or handful of players to compromise the program to the competitive disadvantage of the players who are playing with honor and within the rules.

This rule is effective immediately and will be enforced. The following is a list of rules and guidelines. 1. The two captains should settle all misunderstandings with their fullest cooperation in a spirit of sportsmanship and common sense.ï¿½ On the 1st Night of league play make sure the correct ranking book stats are entered for each player handicap, unranked players must use these stats for first night only (men= 27.0,3.0 / women 17.0, 1.8). 2.

Good Luck...ï¿½ Good Darts!!! SCORING ON THE ELECTRONIC DART MACHINE The score recorded by the machine is the score that the player receives.ï¿½ The players accept that the machine is always right.ï¿½ The only exception will be on the ï¿½Last Dart ï¿½ Winning Dartï¿½ that meets the following criteria: ï¿½ The ï¿½Last Dart ï¿½ Winning Dartï¿½ must stick.

ï¿½ The machine was displaying the ï¿½Throw Dartsï¿½ message and all other rules were followed.ï¿½ Then, no matter if the machine fails to score, or scores incorrectly, the player/team will be credited with the win in that game.ï¿½ Example:ï¿½ Playerï¿½s score is 24 at the beginning of their turn.ï¿½ Their first dart hits and sticks in the 9, but does not register or score.ï¿½ Their second dart scores a single 15, leaving the player on 9.ï¿½ The third dart is then thrown in the single 9, but does not register or score.ï¿½ Since it was the ï¿½Last Dart ï¿½ Winning Dartï¿½, that player wins the game. A dart that sticks in the board but does not activate the electronic scoring may be manually scored as long as the ï¿½Throw Dartsï¿½ message was displayed and the dart machine reads that only two darts have been thrown.

If there is a question to whether the machine is scoring or working properly, STOP THE GAME.ï¿½ Do not remove darts or activate the ï¿½Player Changeï¿½.ï¿½ The team captains must try to solve the problem.ï¿½ If a restart of game is necessary, scores will be re-entered and play will continue.ï¿½ If they are unable to do so, they will need to call for service, make up the rest of the games on a Just Darts score sheet, or reschedule the remaining match within a two (2) week period. If a dart bounces off the board it is considered a dart thrown even if it does not score.ï¿½ It may not be thrown again. If a dart is thrown before the ï¿½Throw Dartsï¿½ message lights, the dart will not score and is considered a dart thrown.ï¿½ It may not be thrown again.
