Online dice roller — free d6 & d20

An online six-sided die roller. Select 6 faces and roll to get a random number from 1 to 6 instantly.

It uses the browser's Math.random() function: pseudo-random and uniform enough for games, raffles and tabletop RPGs, but not suitable for cryptography or gambling.

Yes. Pick 20 sides and roll. d4, d6, d8, d10 and d12 are also available, covering every standard polyhedral die used in Dungeons & Dragons and other RPGs.

Each face of a fair d20 has a 1-in-20 chance (5%). Rolling with advantage (two d20, keep the highest) raises the chance of a natural 20 to 9.75%.

There are 36 combinations. A total of 7 is the most likely (6/36, 16.7%); 2 and 12 are the least likely (1/36, 2.8% each). Totals 6 and 8 each have a 5/36 (13.9%) chance.

Roll the die repeatedly and add the results, or use the multi-dice option when available. For example, 3d6 means rolling three six-sided dice and summing them (range 3-18, average 10.5).
