Adjacent parity changes
One paid round draws three independent uniform pockets0–12. Score counts adjacent odd/even changes: first-to-second plus second-to-third. Zero is even. For2,4,6 score0;2,4,7 score1;2,7,4 score2. All2197 ordered triples are equally likely. This original13-pocket game is not a37-pocket European table.
Three actual score bands
Before spinning choose lower score0,middle score1 orupper score2. Bands contain559,1092 and546 ordered triples of2197 respectively. Three draws use one captured stake; there is no mid-round collect.
Exact probability and total return
Hit probabilities are559/2197,1092/2197 and546/2197. Total return on a hit equals stake×0.96×2197 divided by winning triples:3.773023256,1.931428571 or3.862857143 times stake respectively. These returns include the stake; a miss returns zero.
One stake is deducted before all three draws. Start,stake,band and refill stay locked until settlement. The final adjacent-parity-change count determines the selected band’s gross payout; a miss returns zero. There is no additional charge per component draw.
Expected return
Exact expected return is 96% in every band: hit probability multiplied by the total-return multiplier is 0.96. Bands change hit frequency and variance, not expectation. A 96% expectation is not a promise of a single spin or a short session. This demo does not certify an external operator or reproduce its games.
