The DeXiDice algorithm
Each die has its own distribution
Every die tracks how often each face has been rolled. At the start, all six faces have an equal 16.67% chance — just like a normal die.
Rolling shifts the odds
Each time a face is rolled, its probability decreases slightly for the next roll. The faces that haven't been rolled recently get a higher chance.
Luck evens out over time
After many rolls, every face will have appeared roughly the same number of times. Lucky streaks become less likely — and so do unlucky ones.
Skill takes over
Because everyone ends up with roughly equal distributions, what you do with your rolls starts to matter more than which numbers you happen to roll.
In transparent mode (Statistics: Visible) you can see the current percentage for each face — and use that strategically. In hidden mode the algorithm runs silently in the background.
