In one respect the casino is simpler than the sports board, because there is no opponent to read, and harder in another: every game rests on a house edge that stays the same however the session runs.
A game's theme says little; its volatility says far more. Low-volatility games pay small amounts often and without big swings, while high-volatility ones need a much deeper budget before the features they are known for come round.
The detail matters less than two simple habits. The amount for one session is set before the first stake, and the game is chosen so that its volatility fits it. A win, then, is a good moment to stop — not proof that the run continues.
