RTP (Return to Player) is a frequently misunderstood casino concept. This guide clarifies what RTP means, why it's a game-level figure not a casino-level one, and how to use it practically when choosing what to play.
What RTP Actually Means
RTP is the theoretical percentage of all wagered money that a game returns to players over millions of rounds. A 96% RTP slot returns €96 for every €100 wagered on average — over the long run, across all players. In any single session, results vary enormously from this theoretical average.
RTP is Set by the Game, Not the Casino
The same slot title has the same published RTP whether you play it at Casino A or Casino B — the game's RTP is set by its developer and can't be altered by the casino. This means comparing casinos by "site RTP" is misleading. What matters is finding high-RTP individual games.
Some Casinos Offer Alternate RTP Versions
A minority of casinos negotiate with providers to run a different RTP variant of a game. For example, a slot might be available in 94%, 96%, and 97% configurations. If a casino publishes its game-specific RTP configuration, that's worth checking — but most casinos don't disclose this. The default configuration from the provider is what you'll encounter at most casinos.
Highest RTP Casino Games
- Video Poker (Jacks or Better, 9/6 pay table) — 99.54% with optimal strategy
- Blackjack (European, basic strategy) — ~99.5%
- Baccarat (Banker bet) — 98.94%
- French Roulette (La Partage) — 98.65%
- High-RTP slots — Specific titles like Ugga Bugga (99.07%) or Blood Suckers (98%)
RTP vs Volatility
High RTP doesn't mean frequent wins. High-volatility slots can have respectable RTPs but infrequent large pays. Low-volatility slots have smaller, more frequent wins. Choose volatility based on your session goals and bankroll, not just RTP.

What RTP Actually Means for Your Bankroll
RTP (Return to Player) is the theoretical percentage of all wagers returned to players over millions of spins. A 97% RTP slot returns €97 for every €100 wagered — in theory, over a very long run. In a single session, variance swamps the RTP: a low-volatility 97% game can still produce a £200 swing in either direction within 100 spins.
High-RTP slots help over long play periods, but the best use is to satisfy wagering requirements on casino bonuses — where the lower house edge reduces your average cost to clear the bonus. For bonus wagering, avoid games below 95% RTP and check whether the casino excludes high-RTP titles from bonus play (many do). 18+
96% or above is generally considered good for a slot. Some high-RTP slots exceed 98%. Note that RTP is a long-run theoretical figure — your individual session will vary significantly.
Most can't unilaterally change it, but some providers allow casinos to choose from multiple RTP configurations. If a casino offers a game at 94% when the default is 96%, that's a significant difference. Most casinos run the standard configuration.
Yes, in theoretical terms. At 96% RTP, the house edge is 4%. At 94%, it's 6%. Over 100 spins at €1/spin, the expected difference is €2. Over thousands of spins, it matters more.
No. GRAI issued only remote betting licences in 2026. Casino gaming licences are expected 2027–2028. Irish players use MGA, UKGC, or Gibraltar-licensed casinos.
