Dice Roller

Key features

• Seven die types: d4, d6, d8, d10, d12, d20 and d100, one to twelve dice at a time.
• Modifier from −50 to +50 applied to the total and shown in the spec chip (e.g. 4d6+2).
• Natural 20 and natural 1 on d20s light up as NAT MAX! and NAT 1! — tabletop crit detection built in.
• Full transparency: the formula line shows every die (4 + 3 + 2 − 1 = 8), not just the total.
• Last 10 rolls persist in your browser with spec, total and time — clearable anytime.
• Session stats track roll count, highest total and average; the Space bar rolls from anywhere outside the inputs.

How it works

1. 1

   Build your dice spec

   Set the number of dice, the die type, and an optional modifier. The spec chip updates live, e.g. 2d20+0.

2. 2

   Roll

   Click the big ROLL button or press Space (outside the input fields).

3. 3

   Read the result

   The total lands front and center with the full formula underneath and one tile per die — crits highlighted.

4. 4

   Review your history

   The last ten rolls are listed and saved locally for your next visit; session stats tally your highest and average totals.

Tips for better results

• 💡Space is a real shortcut — it's guarded so it never fires while you're typing in an input.
• 💡Rolling with advantage or disadvantage? Set 2d20 and take the higher or lower die by eye; every die is shown, so nothing is hidden.
• 💡Crit highlighting only applies to d20s — a maximum roll on other dice isn't flagged.
• 💡History is stored per browser (newest first, 10 max); Clear history wipes it from storage too.
• 💡Session stats reset on reload, but saved history does not — handy for telling tonight's session apart from last week's.
