What it is
The Online Dice rolls virtual dice in your browser, with a 3D animation and the full set of shapes: D4, D6, D8, D10, D12 and D20.
What it is for
The commonest case is the die that went missing: mid-board-game, mid-RPG session, or in a classroom activity. Rolling on screen solves it, and everyone around sees the result at the same time.
Uses that come up again and again:
- Tabletop RPG: systems like D&D ask for D4 through D20, and it is rare to have the whole set to hand.
- Board games: replaces the die that was not in the box.
- Classroom: pick who answers, or generate numbers for probability exercises.
- Quick decisions: number the options and roll.
Is the die fair?
Yes. Every roll uses the browser's random number generator, and every face has the same chance. The 3D animation is decoration: the number is drawn first and the animation shows the result.
Worth repeating the thing that trips people up in dice games: rolls are independent. If a D20 came up 1 three times in a row, the fourth roll still has a 1 in 20 chance of a 1. The die is not "due" a high number.
When you roll several dice at once, the likeliest total is in the middle rather than at the extremes. With two D6, rolling a 7 is six times more likely than rolling a 2, because six combinations add to 7 and only one adds to 2.
Other ways to draw
If you need a number in any range rather than a die face, use the random number picker. To choose between written options, the decision wheel, and for two alternatives, the coin flip.
