A free online virtual dice roller supporting D4, D6, D8, D10, D12, and D20. Roll up to 10 dice simultaneously with 3D animation, sum tracking, and roll history.
Welcome to our Virtual Dice Roller, a high-performance web utility built to support tabletop roleplaying games (TTRPGs), classroom mathematical probability sessions, and standard board game play. Supporting all classical polyhedral dice configurations (D4, D6, D8, D10, D12, D20), our roller simulates gravity-driven 3D rotations for D6 cubes and polyhedral models with immediate sum calculation and history logging.
Perform your combat and skill checks using our virtual D20 and other polyhedral models. Ideal as a backup when physical dice are missing or for remote campaign play.
Lost the dice for Yahtzee, Ludo, or Monopoly? Use our multi-dice selector to roll 2 D6 dice instantly on any tablet or smartphone.
Conduct statistical sampling experiments in school. Students can roll multiple dice, record the sums, and chart actual outcomes against mathematical projections.
Use numeric outcomes to split individuals into groups, decide order of turns, or play drinking games and party challenges.
For a single six-sided die (D6), the probability of rolling any number from 1 to 6 is exactly 1/6 (~16.67%). However, when rolling multiple dice (like 2 D6), the probability of the sum of the dice follows a triangular distribution. There is only 1 way to roll a sum of 2 (1+1) and 1 way to roll a 12 (6+6), representing a 2.78% chance. Conversely, a sum of 7 has the highest probability (6/36, or 16.67%) because there are 6 distinct combinations (1+6, 2+5, 3+4, 4+3, 5+2, 6+1) that equal 7.
