How to verify a round
Each spin is one pre-computed outcome (spin, cascades, respins and free spins together), selected by HMAC-SHA256 of the server seed with your client seed and the round number (nonce). The server seed hash is shown first; when you rotate the seed pair the old seed is revealed and you recompute the spin on the Fair play page.
Social game: everything is played with virtual chips, which cannot be withdrawn or exchanged for money or prizes. 18+.
