3D Dice Roller Online

How 3D Dice Rolling Works

This dice roller uses Three.js to render realistic 3D dice in your browser. Each die is a 3D polyhedron — a d4 is a tetrahedron (4 faces), d6 is a cube (6 faces), d8 is an octahedron, d10 is a pentagonal trapezohedron, d12 is a dodecahedron, and d20 is an icosahedron. When you click Roll, the dice are thrown with randomized initial velocity and rotation. The animation simulates physics with gravity, spin, and bounce until each die settles on a face. The result is determined by a cryptographically secure random number generator, ensuring truly fair rolls.

3D Dice for Tabletop RPGs

Tabletop roleplaying games like Dungeons and Dragons, Pathfinder, and Call of Cthulhu rely on dice rolls for combat, skill checks, saving throws, and ability scores. This virtual dice roller supports all standard RPG dice — d4, d6, d8, d10, d12, and d20. Roll multiple dice at once for damage rolls (like 2d6 for a greatsword) or ability score generation (4d6 drop lowest). The roll history keeps track of all your results during a session, so you can reference past rolls without writing them down.

Tips for Using Virtual Dice

For standard D&D ability score generation, select d6 and set the count to 4. Roll and take the best three. For advantage/disadvantage rolls, select d20 and roll 2 — take the higher or lower result. The roll history at the bottom keeps a log of all your rolls, which is useful for combat tracking. You can also use this as a quick random number generator for any situation — classroom activities, choosing randomly from a group, settling disputes, or playing board games remotely with friends.

Fair and Private Dice Rolls

The dice results use the Web Crypto API (crypto.getRandomValues) for cryptographically secure random numbers — the same technology used in encryption and security applications. This ensures each roll is truly random and cannot be predicted. No data is sent to any server. Your roll history stays in your browser and is cleared when you refresh the page. There are no accounts, no tracking, and no way for anyone to see or influence your rolls.

Board Games and Classroom Use

Beyond tabletop RPGs, this dice roller works for any board game that uses standard dice. Play Monopoly, Risk, Yahtzee, backgammon, or any dice-based game remotely with friends. Teachers use virtual dice for probability lessons, random student selection, and classroom games. The visual 3D animation makes dice rolling engaging and fun, especially for younger students learning about probability and randomness.
