Every Casino Game Has an Hourly Rate
Pick your game, bet size and pace, and see what a session, an hour and a year of this actually cost on average.
The formula is short enough to do on a napkin, which is presumably why no casino prints it: expected loss = average bet × bets per minute × minutes × house edge. Bet $2 on a 1% game at ten bets a minute and the maths says you are paying about $12 an hour — roughly cinema pricing, if the cinema occasionally paid you back and occasionally charged triple. The same $2 at the same pace on 4.5% slots costs $54 an hour, and on 7% keno, $84. Identical bet, identical minutes, wildly different bill: the edge and the speed are doing all of the work.
Speed is the underrated half. Crypto originals resolve in a second or two, so 10–20 bets a minute is a relaxed pace and 60 is possible on autobet. A "small" $1 bet at 30 rounds a minute is $1,800 an hour of turnover — $18/hour on a 1% game before variance even enters the room. Slot spins run 8–15 a minute with a far worse edge. This is why session cost, not bet size, is the number to watch: players comfortably lose more at $1 fast than at $5 slow and never feel the difference until the balance shows it.
The yearly line is deliberately uncomfortable. It takes this exact session, repeated daily, and multiplies by 365. An hour a day on that $2 dice pace is about $4,300 a year in expectation; the same hour on slots is over $19,000. Nobody plans a year of sessions, but bankrolls are spent one unplanned session at a time, and the annual figure is what the habit costs if it becomes one.
Two honest caveats. First, these are averages: any single session is dominated by variance, and roughly half will end better than the expected-loss line — that half is what keeps people coming back. Second, expected loss assumes flat betting; chasing losses raises the average bet and the bill with it. If you want to see how long a bankroll survives this arithmetic rather than what it costs per hour, the bankroll calculator runs the gambler's-ruin numbers. And if your real sessions keep beating your planned sessions in length, our responsible gambling page is the more important tool.
Frequently Asked Questions
Is expected loss what I will actually lose?
No — it is the long-run average. A single session can end anywhere from a big win to several times the expected loss. But average many sessions together and the total tracks the formula closely; the edge never misses over volume, only over single evenings.
Why does game choice change the cost so much?
Because the edge varies by a factor of 14 across this list. Blackjack played well costs ~0.5% of turnover; keno costs ~7%. At the same bet and pace, that is the difference between $6 and $84 an hour. Picking the game is the biggest financial decision a casino player makes.
Does betting bigger and slower cost the same as small and fast?
If turnover per hour matches, yes — $10 once a minute costs the same in expectation as $1 ten times a minute. Variance differs (bigger bets swing harder), but the hourly bill is set by turnover × edge, however you compose it.
Can rakeback or bonuses reduce the hourly cost?
Partly. Rakeback refunds a share of turnover × edge — at 20% it turns a $12/hour game into $9.60/hour. Run your numbers through the rakeback calculator to see the exact rebate; it softens the price but never turns it positive.
