RTP Explained: What Return to Player Really Means
Updated on July 6, 2026 by the editorial team
Return to Player, or RTP, is the number that tells you how much a game pays back to players over the long run. A slot with 96% RTP returns C$96 for every C$100 wagered across millions of spins, keeping about C$4 as the house edge. That figure sits behind every title in the Irwin Casino lobby, and once you know how to read it, you pick games with sharper eyes.

What return to player actually buys you
RTP is a percentage. It describes the share of all money bet on a game that flows back to players as winnings, measured over an enormous sample of rounds.
Say a game lists 96.5%. For every C$1,000 fed into it by everyone playing, roughly C$965 comes back out as prizes and C$35 stays with the house. The number is theoretical and long-term, calculated by the game studio and confirmed by independent testing labs before the title ever reaches a lobby.
Here is the practical payoff: a higher RTP means the built-in cost of playing is lower. Pick a slot at 97% over one stuck at 94%, and the math tips a little further in your favour every session. That 3% difference sounds small on paper. Across a night of a few hundred spins at C$1 a go, it changes how long your balance survives before the average catches up. It never guarantees a win. It shifts the odds by a measurable amount, and over hundreds of spins that gap adds up.
Reading the percentage so it works in your favour
The flip side of RTP is the house edge. Subtract the RTP from 100% and you get exactly what the casino keeps. A 96% game carries a 4% edge; a 98% game carries 2%. Lower edge, better value for you.
Most online slots land between 94% and 97%. Anything at 97% or above counts as generous. Drop below 92% and the game is eating your bankroll faster than average, so it pays to check before you commit real money.
One point trips people up. RTP is an average across a massive number of rounds, not a promise for your next hour. You can play a 97% slot and walk away down. You can hit a bonus round on a 94% game and cash out ahead. The percentage describes the machine's behaviour over time, not the size of any single result. Keep that distinction and the number stops feeling like a broken promise and starts working as a filter.
Finding the figure before you spin
You rarely have to guess. Reputable studios publish RTP right inside the game, and Irwin Casino runs titles from Pragmatic Play, Play'n GO, Hacksaw Gaming and Yggdrasil, all of which disclose it.
A few reliable places to look:
- The game's info or rules screen. Open the paytable, usually behind an "i" or menu icon, and scroll to the fine print. The RTP is stated there, often alongside volatility.
- The provider's own site. Studios list RTP for every release. If a slot shows a range like 94.0% to 96.5%, the casino has chosen a specific version, so the in-game screen is the number that counts.
- Independent databases and review pages. Testing bodies such as eCOGRA and iTech Labs audit these figures, and slot databases collect them for quick comparison.
If a game hides its RTP entirely, treat that as a reason to move on. The studios worth your time make the number easy to find, and every title in the lobby here comes from a lab-tested provider that states it up front.
Why the number won't call your session
This is where RTP gets misread most. A published 96% does not mean you get C$96 back from your C$100 tonight. Short sessions swing wildly around the average, and that swing has a name: variance, or volatility.
Two slots can share the same 96% RTP and feel nothing alike. A low-volatility game hands out small wins often, so your balance drifts up and down gently. A high-volatility game stays quiet for long stretches, then pays a large hit that pulls the average back to 96% over thousands of spins you personally will never see in one sitting.
So RTP tells you the long-run cost. Volatility tells you the ride. Read both together. If you want your deposit to last for a relaxed evening, a high-RTP, low-volatility slot stretches your play the furthest. If you are chasing one big result and accept dry spells, high volatility suits you better. The same principle applies to the wagering on any welcome offer you claim, since a slower-burning slot clears playthrough more predictably.

How much games hand back by category
RTP is not uniform across the lobby. Table games with skill or strategy tend to return more than slots, while the payout ceiling on jackpots comes lower because a slice funds the prize pool. The table below shows typical ranges you'll meet across the Irwin Casino floor.
| Game type | Typical RTP range | House edge | What drives it |
|---|---|---|---|
| Blackjack (basic strategy) | 99.0% – 99.6% | 0.4% – 1.0% | Player decisions cut the edge sharply |
| Video poker (optimal play) | 98.0% – 99.5% | 0.5% – 2.0% | Correct holds move the odds close to even |
| Baccarat (banker bet) | 98.5% – 98.9% | 1.1% – 1.5% | Fixed rules, low built-in cost |
| Roulette (European, single zero) | 97.3% | 2.7% | One zero instead of two halves the edge |
| Standard video slots | 94.0% – 97.0% | 3.0% – 6.0% | Set by the studio, varies by title |
| Progressive jackpot slots | 88.0% – 94.0% | 6.0% – 12.0% | Part of each bet feeds the jackpot pool |
The pattern is clear. If you play for value and want your bankroll to stretch, blackjack and video poker sit at the top, and you can compare hands on our video poker guide. Slots deliver the entertainment and the big-win potential, and progressives trade a lower base RTP for a shot at a life-changing prize. None of it changes how fast you get paid, of course, which comes down to your method and our withdrawal times.
RTP questions players ask most
Does a higher RTP mean I will win more often?
Not necessarily. RTP measures how much a game returns over the long run, not how frequently it pays. A high-RTP slot with high volatility can go cold for a long stretch before a big hit. For steadier, smaller wins, pair a strong RTP with lower volatility.
Can a casino change a game's RTP?
The casino cannot rewrite the number on a whim. Studios sometimes release a title in several RTP versions, and the operator selects one. The figure shown on the game's info screen is the version actually running, so that screen is your source of truth.
What is a good RTP for online slots?
Anything at or above 96% is solid, and 97% and up is generous for a slot. Below 94%, the house keeps more than average. Table games like blackjack and video poker return far more, often above 98% with correct play.
Is RTP the same as my odds of winning a spin?
No. RTP is a long-term payback average across millions of rounds. Your chance on any single spin depends on the game's random number generator and its hit frequency, which the RTP figure does not directly reveal.
Where do I check the RTP of an Irwin Casino game?
Open the game, tap the info or menu icon, and read the paytable, where the RTP sits in the fine print. You can also confirm it on the studio's own site. Titles from Pragmatic Play, Play'n GO and the other studios in the lobby all publish the figure. To see how the platform verifies its games, read how online casinos work.
