The Dice Roller is a free online dice roll simulator that brings the randomness of multi‑sided dice to your screen. Designed as both a general‑purpose dice roller and a dedicated DND dice roller, it supports up to 15 dice at once and offers 20 distinct dice types—covering everything from the classic cube to exotic polyhedra. Whether you need a quick random dice roll for a board game or a reliable polyhedral dice roller for tabletop RPGs, this tool delivers fair, instant results.
Using the Dice Simulator
Follow these steps to start rolling:
- Number of dice – Choose any value from 1 to 15.
- Die type – Pick the desired number of sides for each die. The default is a regular six‑sided die. To turn the tool into a d20 roller, select “Icosahedron (20 faces)”.
- Uniform or mixed dice – If you want all dice to be identical, use the “Set all dice types to” dropdown to apply one shape to every die. For a mix of different dice, select the last option in that dropdown and then assign the type for each die individually.
- Roll & reroll – Scroll to the bottom and tick the “Roll” checkbox. To reroll, simply untick and re‑tick the same checkbox.
After each roll you see the total sum of all dice at the bottom; the result of every individual die is displayed above the total.
