Dice Roller & Stats: Roku

Roll dice for your next tabletop RPG session with Roku, a minimalist dice roller designed for D&D, Pathfinder, and board games.

Roll with Advanced Mechanics

Roll standard dice (d4, d6, d8, d10, d12, d20, d100) with D&D-style mechanics including advantage, disadvantage, drop lowest, keep highest, exploding dice, and reroll options. Add modifiers for attack rolls and damage calculations.

Save Custom Presets

Create named presets for your favorite rolls like "Fireball" (8d6) or "Sneak Attack" (2d20 + 1d6 + 3). Mark favorites for quick access. Tap any preset to instantly roll.

Track Your Luck

View session statistics with distribution charts for each die type. Compare your rolls against expected probabilities and see if you're rolling hot or cold. Enable fair dice mode to balance luck over time.

Two Rolling Modes

Switch between Advanced mode (full features) or Simple mode (quick d6 rolls). Perfect for both complex RPG encounters and casual board games.

Dice Notation Support

Enter rolls using standard notation like "3d6+5" or "2d20kh1" (keep highest). Supports drop lowest (dl), keep highest (kh), exploding dice (!), and more.

Multi-Player Sessions

Add players and track per-player statistics. See who's rolling lucky and who needs new dice.

Physics-Based Animation

Watch dice tumble with realistic physics simulation. Smooth animations bring your rolls to life without slowing you down.

Privacy & Design

No ads. No tracking. No accounts required. Session statistics reset when you close the app.

Perfect for D&D 5e, Pathfinder, Call of Cthulhu, and any tabletop game that uses polyhedral dice.
