High RTP slots return more of what is staked over the long run. The figure is a long-run average across millions of spins, not a promise for your session, but between two games you would enjoy equally it is the cleanest way to choose.
The catch is that a slot does not have one RTP. Many providers ship several versions, and the casino picks which one goes live. We read the published figures from the providers' own game pages and configuration data.

One game, four returns
Some studios publish all their versions. Two examples from the providers' own pages:
| Slot | Versions offered to casinos |
|---|---|
| Wanted Dead or a Wild (Hacksaw) | 96.38%, 94.55%, 92.33%, 88.42% |
| Le Bandit (Hacksaw) | 96.34%, 94.23%, 92.17%, 88.36% |
| Chaos Crew 2 (Hacksaw) | 96.27%, 94.22%, 92.41%, 88.28% |
| Wild Swarm (Push Gaming) | 97.03%, 94.67% |
| Jammin' Jars (Push Gaming) | 96.83%, 94.25% |
Our arithmetic for CA$1,000 of spins: about CA$36 expected cost at 96.38%, about CA$116 at 88.42%. Same game, same graphics, more than three times the price.
How to check your casino's version
- Open the slot, then the info, rules or paytable screen.
- Find the line that states the theoretical return. Providers print it there.
- Compare it with the top figure above. If it is lower, the casino runs a lower version; if you care about the difference, play the game somewhere else or play a different game.
We do not list which version each casino runs, because it can change and it can differ by country. The info screen is the only reliable source at the moment you play.
Open the casino and play with a balance you funded by Interac.
RTP and bonuses
A high-RTP slot is the natural choice for clearing a wagering requirement, and casinos know it. Some exclude high-return titles from bonus play; Hellspin's terms exclude jackpot games and a provider list of titles (2b). The excluded list sits in the bonus terms; read it before you play a bonus on a game from the table above. See wagering requirements.
Where to play
Pragmatic Play and Hacksaw Gaming are in the provider lists of Hellspin, Slotsgem and iWild Casino; Push Gaming is in iWild's. Check the version in the info screen and play the highest one you find.
