D12 dice roller
A twelve-sided dodecahedral die used in role-playing games, random tables and rules that call for a 1d12 roll.
How this die works
A D12 has twelve pentagonal faces numbered 1 through 12. Each number has a one-in-twelve chance, about 8.33%. Its average result over many fair rolls is 6.5. The D12 fills the range between the familiar D10 and D20.
When to use it
Use a D12 when a game rule specifies 1d12, for twelve-entry random tables, or for character abilities and damage rolls.
A fair digital roll gives each face an equal chance. This roller uses the browser's secure random number generator where available.
