About the Dice Roller
This dice roller simulates rolling any standard tabletop gaming dice — d4, d6, d8, d10, d12, d20, d100 (percentile) — as well as custom dice with any number of sides, using cryptographically random number generation for fair results. Roll multiple dice simultaneously, add modifiers (e.g. 2d6+3), view individual roll results and totals, and see a roll history for the session. Built for tabletop RPG players (D&D, Pathfinder, Warhammer), board gamers, and anyone who needs a quick virtual dice roll.
