Dice Roller: d6, d8, d20 and Custom Dice

Pick a dice type or enter a custom number of sides, set how many dice go into each roll and how many rolls you want, then hit roll to see every individual face at once.

Add a modifier to apply a flat bonus or penalty to each roll total, matching tabletop notation such as 2d6+3, and copy the whole transcript for your session notes.

Every face uses the browser's cryptographic random source with rejection sampling, so each side is equally likely and no result is ever biased toward the low numbers.
