What is a Dice Roller?
A dice roller is a browser-based random number generator that simulates physical dice rolls. Our online dice roller supports all standard tabletop RPG dice — d4, d6, d8, d10, d12, d20, and d100— as well as any custom-sided die from d2 to d1000. You can roll multiple dice simultaneously, apply numeric modifiers (such as +3 for a strength bonus), and view a complete breakdown of every individual die result. The dice roller uses the browser's built-in random number generation to produce statistically fair results, making it a reliable replacement for physical dice in any game or probability exercise.
How Our Dice Roller Works
- Configure Your Dice: Select a preset die type (d4 through d100) or enter a custom number of sides. Set how many dice to roll (1–100) using the counter or by typing directly. Add a positive or negative modifier to adjust the final total for RPG bonuses and penalties.
- Roll and See Results Instantly: Click the Roll button to generate results. The dice roller animates each die briefly before landing on the final values. Individual die results are displayed with colour coding — green for maximum rolls (critical hits) and red for minimum rolls (critical fails).
- Review Your Roll History: Every roll is automatically saved to the history panel with the dice configuration, individual values, total, modifier, and timestamp. The history stores up to 50 rolls per session and can be cleared at any time. Individual rolls can also be deleted from the history.
What the Dice Roller Supports
- Standard RPG Dice:d4, d6, d8, d10, d12, d20, and d100 (percentile) — the full set used in Dungeons & Dragons, Pathfinder, and most tabletop RPGs.
- Custom Dice: Any die from d2 to d1000 — useful for unusual game mechanics, probability experiments, or generating random numbers in a specific range.
- Dice Pools: Roll up to 100 dice simultaneously — ideal for wargames, dice pool systems like World of Darkness, or any mechanic requiring large numbers of dice at once.
- Modifiers: Add or subtract a flat numeric modifier to the total roll — standard in RPGs for ability score bonuses, proficiency bonuses, and situational adjustments.
Tips for Using the Dice Roller Effectively
For tabletop RPG sessions, keep the dice roller open in a browser tab alongside your character sheet. Use the modifier field to pre-set your attack or skill bonus so you don't need to add it manually each time. The roll history acts as a session log — you can scroll back to verify any contested roll. For dice pool systems, set the count to your full pool size and scan the individual results for successes. The colour coding makes it easy to spot critical hits (green) and critical fails (red) at a glance without reading every number.
