Reroll-Ones Dice Roller
Rolls a set of dice and automatically rerolls any die that lands on 1 (once each) — a common tabletop house rule that softens the worst rolls without removing randomness entirely.
How to use this tool
- Set the dice sides and count.
- Press roll — any 1s are automatically rerolled once and shown alongside the original.
Common use cases
- Tabletop RPG house rules
- Damage rolls with a reroll-1s rule
- Comparing original vs rerolled outcomes
