Independent guide

Three draws and their median
One paid round draws three independent uniform pockets numbered 0–12. Sort the three numbers: their middle number is the score. Choose scores 0–4, 5–8 or 9–12 before starting. All 2197 ordered triples are equally likely.
Exact enumeration of 2197 triples
Draws 12, 2 and 7 sort to 2, 7, 12 and score 7. Repeated numbers remain separate draws: 4, 4, 12 score 4. Exactly 725 triples score 0–4, 976 score 5–8 and 496 score 9–12.
Expected return and variance
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.

How is the score calculated?
One paid round draws three independent uniform pockets numbered 0–12. Sort the three numbers: their middle number is the score. Choose scores 0–4, 5–8 or 9–12 before starting. All 2197 ordered triples are equally likely.
How many triples win?
Draws 12, 2 and 7 sort to 2, 7, 12 and score 7. Repeated numbers remain separate draws: 4, 4, 12 score 4. Exactly 725 triples score 0–4, 976 score 5–8 and 496 score 9–12.
What is the total return?
Hit probabilities are 725/2197, 976/2197 and 496/2197. Total-return multipliers are 2.909131034, 2.160983607 and 4.252258065. A hit returns stake × 0.96 × 2197 divided by the selected winning-triple count, including stake; a miss returns zero.
How many stakes are charged?
One stake covers all three draws. Settings, start and refill are locked until settlement. The selected band pays its displayed total return if it contains the median score. No additional stake is charged for later draws and there is no mid-round cash-out.
