Original demo and external catalogue
No external SL550 catalogue, providers or commercial games have been verified. The original Middle Dial Roulette here uses the median of three 13-pocket draws. It supplies no standard roulette colour, parity, European wheel or straight-up wagers.
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.
One stake and one settlement
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.
Unverified external claims
A matching brand, professional design, search result or HTTPS connection does not verify ownership, authorisation or safety. Match any claim against an independent regulator register, including entity, current status, scope and listed domains. No operator licence or service is endorsed here.
