SL550: Middle Dial Roulette

This independent SL550 guide supplies its own free Middle Dial Roulette demo. Operator identity, domains, licence, apps, payments, support and commercial game equivalence have not been independently verified. No operator account or commercial link is supplied here.

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.

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.

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.

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.

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.

Settled balance and fractional payout carry persist in localStorage. Reloading during a round ends it without refunding its deducted stake. Outside a round, refill sets 1000 coins when balance is below the smallest stake; it does not add 1000 or erase fractional carry. Band and stake return to defaults on reload.

There are no account, payment or identity-document forms here. Fonts, the visit counter, server and CDN requests can expose technical data including IP and browser details. Complete anonymity, third-party data use and cookie lifetimes are not established. Clearing cache alone may leave localStorage intact.

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.

This demo is restricted to adults 18+ and uses coins without cash value or prizes. Set session time and virtual-coin limits before playing, then stop at those limits. Raising a stake to recover losses does not improve expectation. If playing affects responsibilities or becomes hard to control, stop and seek suitable independently verified local support.

Demo coins cannot be exchanged or withdrawn and are unrelated to an operator account. Only this browser’s settled wallet and fractional carry persist. Clearing cache alone may leave localStorage intact; clearing site data removes local progress.

These rules describe only this original virtual game. This guide does not determine legal availability of an external service, certify its fairness or promise income. The own-site 18+ restriction is not a statement about every jurisdiction’s legal age.
