Casino

Category:Terminology
A Casino is a term used by Casino betsson Final Fantasy XI players to describe a setup that is run in towns by other players. A casino is essentially what it sounds like, a place for players to choose to 'bet' a certain amount of gil and then perform a /random command to generate a number between 0 and 999. The result of this 'roll' determines if the players participating wins or loses.
== Casino Types ==
There are two kinds of Casino's in Final Fantasy XI; those run by NPCs, and those run by players.
== NPC Run Casino Locations ==
There are three NPCs in Final Fantasy XI who operate casino's. They are Repat in Norg (H-8), Mileon in Rabao (H-7), and Varchet in Southern San d'Oria (L-6).
== NPC Run Casino Mechanics ==
They way the NPC Casino's work is as follows:
- A Player trades the NPC 100gil
- The player then automatically rolls a random number between 1 and 6
- The value rolled by the player is then added to a running total
- If the current player pushes the running total above 400, then the player wins 10,000gil
Technical Information:
~ When a player wins, the running total is reset to 0
~ If a player pushes the running total to exactly 400, they win 10,000gil as well as an additional random prize
~ The two Casino NPCs share one running total between them
== NPC Run Casinos: Chances of Winning ==
Your chance of winning off one roll
p = 1/6 * (6+5+4+3+2+1)/400 = 0.00875
So each time you play, you can expect to win the following amount of gil
E = 10000p - 100(1-p) = -11.625gil
In other words, you will lose on average 11.625gil per play. So the house has the advantage.
So what are you chances of hitting it big and winning?
1/p = 114.29 plays
So, if you were to play until you won, then (on average) you would be spending 11,400gil and win 10,000gil, resulting in a lose of 1,400gil.
== Player Run Casino Locations ==
Casino's can technically be located in any town; however, they are usually when players tend to congregate normally. The most common places are in Lower Jeuno near the Auction House, and in the Aht Urhgan Whitegate above the Mog House.
== Player Run Casino Mechanics ==
Casino's work in a variety of different ways with different rules based on the player who is running the casino. The general template used is below.
Roll Winnings
1-600 Player loses bet
601-900 Player wins 2x their bet
901-999 Player wins 3x their bet
This is just an example. Some casino's are built where if a player rolls a 1 or a 999 they win more. Others will adjust the above numbers to what the casino operator feels comfortable with. In all cases, casino's are designed such that, in the long run, the operator will generate a profit.
== Player Run Casinos: Chances of Winning ==
Chances of winning depend on the odds that the casino operator has setup, as well as the players bet. With the numbers given above, you have the following chances.
You have a 60% chance to lose your bet outright, so...
X=-(.6 * 100)
Then you have a 30% chance to get your original bet back, as well as an additional 1000, so...
Y=(.299 * 100)
Finally, you have a 10% chance to win your original bet, and an additional 2000, so...
Z=(.099 * 200)
X + Y + Z = -60 + 29.9 + 19.8 = -10.3
So, in the end, on average, for each bet of 1000gil, you will lose 10.3% of whatever you bet each time. In the long run, you will ultimately lose no matter which Casino you play. The key to making money would be to quit while you're ahead.
