Dice Probability Calculator

Formula used

P(win)=(100−T)/100 · M₉₉=0.99/P(win)

What this tool calculates

Enter a roll-over threshold to calculate Dice win probability, zero-edge fair multiplier and the 99% RTP multiplier from the published formula.

How to calculate Dice win probability

For this continuous roll-over model, a threshold T gives P(win) = (100 - T) / 100. At T = 50, the win chance is 50%, the zero-edge multiplier is 2.00x, and the 99% RTP model multiplier is 1.98x.

The multiplier includes the returned stake: 0.50 × 1.98 = 0.99 expected units returned per unit wagered. It does not mean a guaranteed return in a short session.

Does this calculator apply to BetFury or Bitsler?

This is a standalone mathematical model, not an official BetFury or Bitsler calculator. Check each provider's roll range, strict or inclusive threshold, house edge and payout rounding before applying the result.

A finite roll grid can differ from this continuous formula at boundary values. The tool does not inspect another site's rules or predict a future roll.
