Roll-under and roll-over payouts
Crypto dice rolls a number between 0 and 99.99 and you bet on it landing under or over your target. The multiplier is simply (1 - house edge) divided by your win chance, which is why the paytable is perfectly smooth from 1.01x to several hundred x.
Set your target and direction to see the multiplier your casino will offer, the expected value per roll and how likely a losing run is over a session.
Rolls land between 0.00 and 99.99.

The multiplier is (1 - house edge) / win chance, exactly how provably fair dice clients price every target.
How to read the results
- Roll-under 50 gives roughly a 50% win chance and pays close to 1.98x at a 1% edge.
- The multiplier and win chance always multiply out to 1 minus the house edge.
- Lose streak shows the chance of never winning across the number of rolls you enter.
- Direction (under or over) is cosmetic — the maths is identical at mirrored targets.
Frequently asked questions
What is the best target in crypto dice?
Every target has identical expected value. Low targets pay big and rarely; high targets grind small wins. Choose based on the variance your bankroll can absorb, not on expected profit.
What is the house edge on dice?
Typically 1% on crypto casinos, and 2% on some. Enter the published edge to reproduce the exact multipliers shown in your casino's dice client.
Is provably fair dice actually random?
Each roll is derived from a hashed server seed, your client seed and a nonce. You can verify any past roll after rotating the seed, which proves the casino did not change the outcome after your bet.
