RISK does not modify dice rolling odds in favour of computer players in any of the difficulty settings.
RISK does not modify dice rolling odds in favour of higher-ranked players.
In technical terms, one of the most widely used pseudorandom number generators (PRNG) is used to randomize all dice rolls.
We use the Mersenne Twister for cards, player order and dice to provide random http://www.math.sci.hiroshima-u.ac.jp/~m-mat/MT/emt.html
The RISK dice rolling algorithm is tested against a control probability matrix of expected attack and defence dice rolls. We then compare and check the results of each of these tests for variance between our dice rolling outcomes and the control. The results are within +-5% of the control comparison, which is acceptable.
Typically, as a player when we get an unfavourable dice roll, we tend to remember the negative outcomes more than positive ones. So, it can sometimes seem that the dice aren't rolling in our favour. To maximise your chances of winning, here are a few tips on dice rolling strategy.
NEW for AUG 2019 augmentation with some of the new modes/rules
- Human attacking Zombie: Ties favor attacker instead of defender
- Zombie attacking Human: -1 max attack die (so one less die)
- Player attacking Capital: +1 max defender die (an extra die added)
- Attacking over Wall: +1 max defender die (an extra die added)
- These also STACK! So zombies attacking over a wall = 1 less attacker die, 1 more defender die
Here is a reddit thread where someone decompiled the game to confirm what we do with dice.
Note: since 2018 we have disabled the "hacking" that this user specified. It's no longer possible.
And for some context here are two people we know who had this experience at a casinos.
Sometimes random is too random!
