Exploding Dice Roller
Rolls a set of dice using the common tabletop-RPG 'exploding dice' house rule: any die that lands on its maximum face is rerolled and added again, chaining for as long as maximum faces keep appearing (capped so it can never run forever). Described in system-neutral terms and not tied to any specific published game.
What this generator does
Rolls dice where the maximum result triggers another roll that adds to the total, so a lucky die can keep going. It is why some systems have no upper limit on a roll despite using ordinary dice.
How to use this tool
- Set the number of sides and dice.
- Press roll.
- See every individual roll plus the running total.
Common use cases
- Tabletop RPGs using an exploding-dice house rule
- Adding extra swing to a dice game
- Teaching probability with a fun twist
Limitations and good to know
- Because a maximum result rolls again, there is no theoretical ceiling on the total — very high results are rare but not impossible. The average is higher than the same dice rolled without the rule.
