Dice Roller for the whole room
Big, honest dice for math games, probability lessons, and "who goes first." Up to six dice, four-sided to twenty-sided, with the total added up for you.
Classroom uses beyond "roll for it"
Two d6 and a hundred-chart is a full math station: roll, add, cover the sum, and you're quietly drilling addition facts. Roll one d10 twice for two-digit place-value practice ("first roll is tens"). A d20 turns any review worksheet into a game — students roll to pick which question they answer. And for probability units, six d6 rolled thirty times generates a real dataset for a histogram in about two minutes, which beats a textbook table every time.
The visible total matters more than it looks: it lets early-elementary students self-check their mental addition, and it settles board-game disputes instantly on the projector where everyone can see the same roll.
Frequently asked questions
Are the rolls fair?
Yes — each die uses your browser’s random number generator independently, so every face is equally likely on every roll, just like physical dice (minus the one that always rolls off the desk).
Which dice does it support?
d4, d6, d8, d10, d12, and d20, up to six at once. Mixing die types in one roll isn’t supported yet — tell us if your game needs it.
Why is there a total?
Most classroom dice games — adding practice, board-game math, probability experiments — care about the sum. It’s computed for you so younger students can check their own addition against it.
Can students see it from their desks?
Click Fullscreen: the dice grow to fill the screen with nothing else visible. Roll with the button or the spacebar.
