What is Dice Roller?
Dice Roller provides virtual polyhedral tabletop dice rolling for tabletop roleplaying games like Dungeons & Dragons, Pathfinder, Warhammer, and classic family board games. Supporting standard gaming dice including D4, D6, D8, D10, D12, D20, and percentile D100, the tool generates cryptographically uniform random integer rolls with optional arithmetic modifiers. You can roll individual dice, assemble complex multi-dice damage pools, track critical natural 20s and critical 1s, and review complete roll logs. Perfect for dungeon masters, board game players, math students, and remote RPG campaigns without physical dice bags.
