A typical verification record distinguishes a server seed, client seed and nonce. The exact conversion from those inputs to a result is game-specific.
A pre-published server-seed hash is a commitment; the revealed seed is needed later to check that commitment and reproduce the calculation.
Keep the round identifier and inputs shown by the fairness panel. Screenshots of a multiplier alone cannot reconstruct a round.
Check the algorithm for the exact game. A procedure for Dice should not be applied unchanged to Plinko or a live wheel.
Verification checks consistency with the disclosed procedure. It does not make a negative-expected-value game profitable.
RTP is a long-run theoretical measure. It does not mean that one player gets the stated percentage back during a short session.
