Roll Curve

**Roll Curve** is an idle dice mechanic that allows you to increase the probability to roll higher numbers. This includes multiplier dice. It is considered to be one of the most important upgrades in Idle Dice. It also allows you to roll better combos.

At first, it may seem useless if you just upgrade it a little bit. However, by the time you upgrade **Roll Curve** to 4-5 (30-40 upgrades), it completely wipes your chance to roll the lowest number to about 0.0001%. This also increases the chance of rolling a total of 1,000 of a type of combo.

As you get into extremely high **Roll Curve** numbers, like 100+, which is about 1,000 upgrades, it will increase the frequency of getting a five combo which will help you towards the achievement called **Cheating** which requires you to roll 100 five combos in a row.

The code is:

```
var frac = Math.pow(rnd.frac(),1/rollCurve);
var int = Math.floor(this.min + (frac * (this.max - this.min + 1)));

```

Edit: I'm not the original creator of this page but I thought it might be useful to update this information and put a strategy for an end-game 100% play through as I haven't seen much on this yet. I have an estimate of what the code equals. To a lot of programmers this is definitely a very simple equation, but I don't use Java, plus this code is taken out of context, and I can't know some aspects like what object we are looking at (like the this.max or .min) so I replaced it with an educated guess of the real values. I'm pretty sure it's just the dice max/min values (ex. D20 would be min 1 and max 20). I have a full graph of what this would come out to most of the time (in an average sense of what you would typically roll) on Desmos.com (Link). In an average sense, the typical value of a die rolled randomly would come to a 3, or 1/2 of the dice's max value, therefore we can replace the rnd.frac part of the equation with 0.5. I've calculated it, and one of the most efficient ways to get 100 fives in a row is to have a ~1% chance of that happening, which surprisingly comes out to around a level 100 roll curve. This requires about 1e1200 luck, so I'd recommend around 1e1000 or such and you'll be fine. Cheating should be your last achievement (or if you're like me and still haven't gotten no life yet) as I'd suggest having the duel grand champion 0.0001% prestige bonus plus 71% interest to get that many points and luck. Having 200 casinos so you can get a higher luck multiplier is also useful, but it really doesn't matter when you have over e100 luck, so getting a level 1000+ dice multi per roll is smartest. You should turn off autospin for your roulette and stay on the duel page until you have about an extra e500-1000 more points than the last time you checked, and then go back to the main dice to upgrade and get prestige. You need about e7000-10000 points to get enough luck, so get ready to leave your computer running for ten hours. Before you run your computer though, you should gain about e150-200 luck just so you have a high combo increase, maxed reroll and focus chance, a decent prestige multi and a good dice multi + combo multi from the roll curve. I personally, also slot spinned for a x1mil+ combo multi bonus, but that's not crucial, I just had extra slot spins.
