How Different Casino Games Rank in Terms of RTP

Let’s have a quick look at some examples to demonstrate how the RTP works in different casino games. For the sake of simplicity, we shall start with the wheel-based game of roulette where outcomes are fully based on chance and completely independent from each other.


A single-zero roulette game carries a house edge of 2.70%, which is to say the theoretical return to player equals 100% – 2.70% = 97.30%. After a sufficient number of trials, the probabilities even out so that players lose approximately 0.027 cents per every dollar wagered. Add an extra zero for 38 numbered pockets on the wheel, and the player return drops to 94.74%, with a twice as high house edge of 5.26%.


Similarly to roulette, craps is a chance-based game of independent trials. One major difference between the two is that here house edges and player return percentages vary across the board, depending on the type of bets one makes. A person who plays the pass line without odds faces a house edge of 1.41% and will win back approximately 98.59% of their total wagers over time. The contrast is enormous when you compare pass line wagers with Big Red (Any 7) bets, which carry a house edge of 16.70% and only return 83.30% of total wagers in the long turn.

3Video Poker

Return percentages in video poker depend on payouts which is why comparing the games’ paytables at your preferred casinos is of utmost importance for your long-term profitability. Let’s assume casino A offers a 9/6 paytable for Jacks or Better video poker – this is to say flushes pay at odds of 6 to 1, whereas a full house yields a 9 to 1 payout.

In one such “full-pay” variation, the overall return to player is rather high at 99.54%. In the meantime, casino B offers 8/5 Jacks or Better where the payout reduction for a flush and a full house causes the RTP to drop 97.30%. A sensible Jacks or Better player would choose to enjoy their favorite game in Casino A rather than Casino B any day.


As far as slots go, return percentages vary wildly across the board, and usually range anywhere between 80% and 99%. House edges and return to player are influenced by a variety of factors, including paytables, combinations, and in-game features. The good news is most properly regulated casinos publish the percentages of their entire slot catalogs so that players can check and compare the games’ RTP. Another way to figure out the player return of your chosen slot is by opening the help section where such information is normally available.

The above-listed games (bar video poker) rely on pure chance and require no strategy. Most also have a high hit frequency, especially even-odds bets in roulette and pass line wagers in craps. One key thing to note here is that the lower the win frequency of a given game is, the more rounds are required for it to arrive at its target return percentage.
