How to Use This Dice Roller

Click a die type (D4 through D20) to select it. Use the + and − buttons to choose how many dice to roll at once — great for rolling 2d6 damage or 4d6 for character stats. Hit Roll the Dice, or press Space on your keyboard. Results appear instantly with individual die values and a total sum. Your last 20 rolls are saved in the history below.

What Is a Nat 20?

A "Natural 20" (Nat 20) is the highest possible result on a D20 roll — a critical success in Dungeons & Dragons and most d20-based RPGs. It means your attack, skill check, or saving throw automatically succeeds, often with bonus effects. Our roller highlights critical hits in gold so you never miss the moment.

Rolling Multiple Dice

Many games call for rolling multiple dice together — "2d6" means two six-sided dice, "4d8" means four eight-sided dice. Use our quantity selector to roll up to 20 dice at once. The total is displayed prominently so you can apply it directly to your game without mental math.
