RTP vs house edge
RTP and house edge are the same number written two ways: a 96% RTP slot has a 4% house edge, because edge equals 100% minus RTP. Payout speed measures something else entirely, namely how fast the casino processes your withdrawal.Casino marketing blends all three into phrases like "best payout casino", and untangling them is worth five minutes, because two of them describe the price of the game and one describes the cashier's queue.
One price, two notations
Slots quote their price as RTP, the share of stakes returned to players over the long run. Table games historically quote the complement, house edge, the share kept. The conversion is trivial in both directions: a 96.5% RTP slot keeps 3.5%, and single-zero roulette's 2.7% edge (one losing number in 37) is a 97.3% RTP. Blackjack played with sound basic strategy runs around a 0.5% edge under reasonable rules, or roughly 99.5% RTP. Written side by side, the notation stops mattering and the comparison becomes obvious: on price per dollar wagered, good blackjack is cheaper than roulette, which is cheaper than almost every slot.
Why price per bet still misleads
The number that actually hits your wallet is cost per hour, which is edge × stake × bets per hour. Speed of play is the hidden variable. A $1 slot spun 500 times an hour at a 4% edge costs an expected $20 per hour; $10 blackjack hands at 0.5% and 80 hands an hour cost an expected $4, despite the tenfold bigger stake. Reasonable people can prefer either. The mistake is comparing games on RTP alone while ignoring how many bets an hour the format extracts from you. Our session-cost calculator does this arithmetic for any combination of stake, pace and RTP, and volatility then determines how far a single session can wander from that expected line.
The same lens sharpens slot-to-slot comparisons. Moving from a 94% version of a game to a 97% one cuts the edge from 6% to 3%, which halves the expected cost of every hour at the same stake and pace. Presented as "94 vs 97", the difference looks like rounding; presented as house edge, it is a factor of two. Whenever two numbers sit close to 100%, subtract them from 100 before comparing. Edges differ far more than RTPs appear to.
Payout speed is logistics, not math
Payout speed has no connection to the odds. It is operational: how long the casino takes to approve a withdrawal and how long the payment rail takes to settle it. Crypto casinos hold a genuine advantage here, with approved withdrawals commonly clearing within the hour and often within minutes on fast chains, versus days for bank-routed cashouts. However, a casino that pays quickly is not "looser", and a slow one is not "tighter"; the games' math is identical either way. When a ranking praises "payout %" and "fast payouts" in the same breath, note that the first is game RTP and the second is cashier performance. They are set by different parties: the provider ships the RTP (often in several versions the casino chooses between), while the operator controls approval times, KYC friction and withdrawal limits. Per-casino processing behavior is exactly the kind of thing we track in our casino reviews.
Three questions, three numbers
"How expensive is this game?" is answered by RTP or house edge, plus your pace of play. "How rough will the ride be?" is answered by volatility and hit frequency, not by any of the numbers above. "Will I actually get my money, and when?" is answered by the operator's withdrawal record, license reality and KYC policy. No single metric answers more than one of the three, and any site claiming otherwise is compressing for marketing effect.
Keeping them straight
- House edge = 100% − RTP. Same fact, opposite sign. Neither predicts a session.
- Compare formats on cost per hour: edge × stake × bets per hour.
- Treat payout speed as a trust and logistics signal about the operator, never as information about the games.
- Check the RTP in your casino's own paytable; the same slot ships in multiple versions.
