How many dice can I roll?

From 1 to 100, set with the slider or the number input. Every roll renders all of them on a grid so you can read each individual result, not just the total. Useful when you need to count specific pip values (Yahtzee scoring, RPG critical-hit checks).

What kind of dice are these?

Standard six-sided dice (d6), each showing 1 to 6 pips. The total sums all dice in the current roll and the average is that total divided by the number of dice. Other polyhedral dice (d4, d8, d10, d12, d20) are not yet in the tool · only the d6.

Yes. Every die is rolled independently using the browser's pseudorandom number generator (Math.random), so a fresh set comes up each time you tap Roll. The rolls are independent of each other and of previous sessions · there is no "due for a six" bias.

How can I use it for a probability demo?

Roll 5 dice and note the average · it will swing widely between throws (sometimes 2.4, sometimes 4.6). Roll 100 dice and the average will reliably settle near 3.5, the theoretical expected value for a fair six-sided die. That's the Law of Large Numbers in action and a classic classroom demo.

Does it work offline?

Yes. PlayMemorize is a Progressive Web App. Install once and the Dice Roller works without an internet connection.
