probability formulas

How the Spin Odds Work

At least one hit

1 − (1 − p)^N. Initial Spins use the final prize chance; Physical Rolls use the six wheel probabilities.

Automatic Respin

Respins take 10% of wheel landings. For Initial Spins, the five final prizes share the remaining 90%.

Diamond expected value

One physical roll averages 54.25 Diamonds. One Initial Spin averages 54.25 / 0.9 = 60.2778 Diamonds before assigning any value to Bucket prizes.

These are probability estimates, not guaranteed results. Actual rewards can vary, especially over a small number of spins.
