How to use the Dice Roller
Tabletop games from Monopoly to Dungeons & Dragons depend on dice, and a dice roller helps when you have lost yours or you are playing online. Roll quickly and fairly without rummaging through a box.
The tool understands standard dice notation, written as NdS+M: N is how many dice to roll, S is the number of sides, and M is an optional bonus or penalty. So 3d8+2 means roll three eight-sided dice and add two. Type your own notation or tap a preset such as d20 or 2d6, and the individual dice appear along with the total and the full sum.
Rolls use your browser’s secure random generator and an unbiased method, so every face is equally likely. You can roll up to 100 dice with 2 to 1,000 sides, which covers all the standard polyhedral dice used in role-playing games, plus unusual ones.
A few facts that help in play: with two six-sided dice, 7 is the most likely total because six combinations make it, while 2 and 12 each have only one. In many role-playing games, a d20 roll above a target number represents success, and rolling several dice and adding them tends to cluster results around the average. If you only need a single random number in a range, try the random number generator.
