Poker Cash Games vs Tournaments: Structure, Variance and Cost

Poker is the one floor game where you play against people, not the house — which changes what "cost" and "variance" mean entirely.

How the room makes money

• Cash games: the house takes rake — a capped percentage of each pot, posted at the table.
• Tournaments: a fee on top of the buy-in (the "+10" in "$100+10").

That is the entire house edge. Everything else is a transfer between players — your true cost depends on the gap between your skill and the table's.

Structural differences that matter

• Cash: blinds stay fixed; you buy in for real money, leave when you want, and every decision has direct dollar value. Variance is moderate; bankroll pressure is continuous.
• Tournaments: escalating blinds force action; you cannot leave with your stack — you finish in the money or with nothing. Variance is extreme: even excellent players cash a minority of events. The compensation is leverage — small buy-ins can return large multiples.

Choosing, honestly

• Want session control and steady play? Cash.
• Want a defined maximum loss and a shot at a big score? Tournaments — and treat the buy-in as fully spent when you register, the same discipline as Setting Casino Time and Money Limits Before You Play.
• Either way, the etiquette basics from Your First Visit to River Rock Casino apply; specifics of River Rock's current poker offering are pending verification in our poker room guide.

Bankroll reality

Common guidance among serious players: 20–40 buy-ins for cash stakes and 50–100+ for tournaments, precisely because of the variance shapes above. If those numbers feel unreachable, play lower — the game is identical, only the money is smaller.
