Win chance and the gross payout multiplier
For a binary full-loss game with probability p and house edge h, the consistent gross multiplier is (1−h)/p. At 50% and 1% edge it is 1.98: a $10 win returns $19.80 and earns $9.80; expected net is −$0.10.
The chance must come from the actual roll range, threshold and comparison rule. A roll-under threshold of 50 on a continuous uniform 0-to-100 model gives 50%, but discrete endpoints and rounding can alter this. The tool does not assume a named operator’s current rules.
The illustrative simulation repeats independent binary draws at your supplied probability and reports the sample win frequency and mean net. Sampling variation changes those results; the analytical expected value remains the reference.
Dice probability and provably fair verification
A provably fair verification protocol checks a defined seed commitment and outcome conversion. It does not predict a hidden seed or guarantee profit. The provably fair guide explains the information required for verification.
Use the physical dice calculator for ordinary dice sums; that model is different from a software roll range.
