1OR2 Mr Mini Roulette uses a compact wheel with 12 numbers (1–12), six red and six black. There is no zero. Each spin lands on exactly one number, and every number has the same chance (1 in 12).

Example: $1 on a single number that wins returns (your $1 stake + profit). Your balance is kept in whole cents: if a win includes a part of a cent (for example $0.10 × 1.94 = $0.194), the part of a cent is kept for you and added to a later win, so small bets get the full return too.
The theoretical return to player (RTP) is for every bet type: each bet pays × 12 ÷ (numbers covered). The house edge is . RTP is a long-run average over a very large number of spins; single sessions can be far above or below it.
Every result is drawn on the 1OR2BET server with a cryptographic random generator and can be checked afterwards (Settings → Provably fair). The result never depends on who you are, how much you bet, or what happened in earlier spins. If your connection drops during a spin, the spin still completes on the server and you'll see the result when you're back. History shows your own completed spins.
Each result is computed as HMAC-SHA256(server seed, “client seed:nonce:0”), read as 4-byte numbers v; values at or above 4,294,967,292 are skipped, and the result is v mod 12 + 1. You see the SHA-256 hash of the server seed before you play; change the seed to reveal it and check every spin you made with it.
