Dice odds & fairness
- Dice Probability CalculatorThe exact distribution of any dice total — every outcome counted, not simulated, with the odds of rolling at least a given number.
- Shut the Box SolverLists every legal move for a roll and gives each one an exact chance of shutting the box, computed over all 512 positions rather than simulated.
- Five-Dice Hold OptimiserWhich of your five dice to keep, worked out over every outcome of every choice rather than guessed.
- Non-Transitive Dice GeneratorSets of dice arranged in a ring, where each one beats the next and none of them is the best.
- Push-Your-Luck Stopping CalculatorThe pot at which rolling again stops paying, worked out exactly for any die and any busting face.
- Sicherman Dice FinderEvery pair of dice numbered differently from the usual that still rolls totals exactly like an ordinary pair.
- Ability Score Odds CalculatorGives the exact distribution for rolling dice and dropping the lowest, and the real chance of a maximum somewhere in a set.
- Dice Fairness TestRuns a chi-square test on your recorded rolls and is clear that failing to find bias is not the same as proving fairness.
Themed & labelled dice
- Story Dice GeneratorRoll several story-prompt dice at once and weave the words together into a tale.

Choosing the right dice tool
Virtual dice for tabletop games, board games and anywhere a physical set is not to hand. Every die is rolled independently with cryptographic randomness — the standard rollers also accept a seed, for the rare case where a sequence of rolls has to be repeatable — and the individual results are always shown alongside the total, because plenty of rules care about a single die rather than the sum. A second group here does not roll at all. The odds and fairness tools count outcomes instead of sampling them: the exact distribution of a total, the best dice to hold, the point at which rolling again stops paying, and a chi-square test for a physical die you suspect.
- Dice Roller
- Several dice of the same size, with an optional modifier added to the total.
- Polyhedral and d20 rollers
- You want a specific die size to hand without configuring anything. These are filed under Board Games and linked under “Also useful” above.
- Multiple Custom Dice Roller
- The roll mixes different die sizes, such as a d20 alongside two d6.
- Keep-highest and keep-lowest rollers
- The rules ask you to roll several and discard some, as with advantage.
- Dice Probability Calculator
- You want the exact chance of a total rather than a roll — every outcome counted, not simulated.
- Dice Fairness Test
- You have a real die and a tally of its rolls, and want to know whether the unevenness is more than chance would produce.
