A classic die appears on your board, ready to roll.
The dock · Take turns
Dice
Roll dice, flip coins, pick letters — randomness on tap.
One widget, every kind of random: dice by the handful, coin flips, random letters and numbers, even rock-paper-scissors. If a decision needs luck, this settles it.

How it works
Three steps, zero setup
No setup screen, no import wizard — Dice lives on the same board as everything else and it's running before the class has sat down.
2
Pick a mode
Dice, coin flip, random letter, random number, your own list of choices, colours, maths operations or rock-paper-scissors.
Roll
Tap and it tumbles, sound and all. Multiple dice show a running total automatically.
Classroom ideas
Try it tomorrow
Three ways teachers actually run dice — steal one for tomorrow morning.
Maths-fact tray
Two dice: race to multiply the pair. Three dice: build the biggest three-digit number. The tray totals itself while they check.
Story spinner
Choice mode with characters, settings and problems — roll a hero, a place and a disaster, and the writing prompt writes itself.
Probability lab
Predict, then roll one die thirty times and tally. The gap between what they expected and what happened is the whole lesson.
The wheel ended the 'you always pick the same people' complaints on day one. Remove-after-pick might be the fairest thing in my room.
Same dock, one tap away 
Pairs well with
Every tool lives on the same board — these turn dice into a whole routine.
…and the rest of the dock is one tap away:
FAQ
Good to know
Can I roll more than one die?
Yes — build a tray of dice and it totals them for you. Handy for probability lessons and board games alike.
Does it do coin flips?
Heads or tails, one tap. There's also a rock-paper-scissors mode for settling the truly important disputes.
Can it pick from my own list?
Yes — choice mode rolls on any options you type in, so 'which table shares first' takes zero deliberation.
Can it avoid repeats?
Turn on avoid-repeats and it won't land on the same result again until it's used up the alternatives.
Do I need an account to try it?
No — open a board and roll, no login or install. Boards save on this device; an account only matters across devices.
Put dice on your board
Open a board, tap the dock, and it's there. That's the whole setup.
