Wheel

Each colour is a prize: Grey 0× (about 31%), Blue 1.1× (about 49%), Green 1.5× (14%), Yellow 2× (5%) and Red 10× (1%). Every spin is the same, with an RTP of about 95%.

Each colour is split into a few pieces around the wheel, and a piece's width is exactly its chance: the red 10× piece is the narrowest at 1%, the blue pieces the widest. The wheel you see is the real odds.

The first float from the server seed, client seed and nonce decides everything: floor(float × 10,000,000) picks the prize from the table (0× first, then 1.1×, 1.5×, 2×, 10×), and where it falls inside that prize picks the piece and the point the pointer stops at.
