Dice Pool Roller
Roll a pool of dice and count how many meet or beat a chosen success threshold — a common mechanic in dice-pool style tabletop games.
What this generator does
Rolls a pool of dice and counts how many meet or beat a target number, rather than adding them up. This is the core mechanic of several tabletop systems, where the question is how many successes you scored, not what the total was.
How to use this tool
- Choose the number of sides per die.
- Choose how many dice to roll.
- Set a success threshold.
- Roll to see each result and the success count.
Understanding the controls
- Pool size
- How many dice are rolled. More dice means more chances at a success, and the success count grows roughly in proportion.
- Target number
- The value a die must reach to count as a success. Lowering it makes each die more likely to succeed.
Common use cases
- Dice-pool tabletop RPG systems
- Custom probability games
- Classroom probability demonstrations
