About this Dice Roller
Dice have been used for games, divination, and decision-making for over 5,000 years — the oldest known dice were found in a Bronze Age backgammon set dating to 3000 BC in Iran. The standard D6 cube is the most familiar, but polyhedral dice with 4, 8, 10, 12, 20, and 100 sides are essential for modern tabletop roleplaying games like Dungeons & Dragons. Each die type has a specific role in RPG mechanics. The D20 is the central resolution die in D&D 5e — roll it for attack rolls, ability checks, and saving throws. A roll of 20 on a D20 is a 'natural 20' (critical hit), while rolling a 1 is a critical failure. The D8 is commonly used for hit dice and weapon damage. D6s appear in Shadowrun, the original WoD system, and countless board games. The D100 (or percentile) uses two D10s to generate outcomes from 1 to 100 and is common in Call of Cthulhu and WFRP skill checks. Our dice roller uses the browser's cryptographic random source to simulate fair dice rolls. For physical dice, studies have found that precision-machined casino dice are the fairest, while cheap plastic dice can roll high numbers more often due to hollows and imperfect weight distribution. Our virtual dice are perfectly balanced.
Frequently Asked Questions
Our dice roller supports all standard tabletop RPG dice: D4 (4 sides), D6 (standard die), D8, D10, D12, D20, and D100 (percentile). You can roll up to 10 dice of the same type in a single roll.
The D20 (20-sided die) is the core die of Dungeons & Dragons and most tabletop RPGs. It's used for attack rolls, ability checks, and saving throws. Rolling a 20 is a natural 20 (critical hit), and rolling a 1 is a critical failure.
A D100 (or percentile die) generates a random number from 1 to 100. In tabletop RPGs it's often used for random events, loot tables, or percentage-chance outcomes. It's equivalent to rolling two 10-sided dice together (one for tens, one for units).
Rolling with advantage means rolling two D20s and taking the higher result. Set the dice count to 2 and the type to D20, then take the higher of the two numbers shown. Rolling with disadvantage works the same way but you take the lower number.
