About this tool
A weighted die lets you decide how likely each face is. Bump up your lucky number, tilt the odds for a game, or use it to demonstrate probability in class — this simulator respects exactly the weights you set, with no loaded physical dice needed.
How to use it
- Pick a die type (d4, d6, d8, d10, d12 or d20).
- Set a weight for each face (higher = more likely).
- Tap Roll to get a result that follows your odds.
- Adjust the weights and roll again.
Frequently asked questions

- No — it's a probability simulator. Nothing is hidden or rigged; it simply follows the odds you set, which makes it ideal for teaching probability without tampering with real dice.
- Is the roll still random?
- Yes — the outcome is random, it just follows the probabilities you've chosen.
