Key takeaways
- RTP (Return to Player) is a theoretical long-run average calculated over millions of simulated spins, not a promise about your next session.
- House edge is simply 100% minus RTP — a 96% RTP pokie has a 4% house edge.
- Two games can share the same RTP but feel completely different depending on volatility (how often and how large payouts land).
- Progressive jackpot games like Mega Moolah typically show a lower base RTP because a slice of every bet feeds the jackpot pool.
What RTP actually measures
Return to Player is calculated by the game developer (not the casino) by running millions of simulated spins through the game's math model and measuring how much of the total wagered amount was paid back out. A 96% RTP pokie is designed, over an enormous sample size, to pay back NZ$96 for every NZ$100 wagered across all players combined — not you individually, and not tonight. In any single session, or even a few thousand spins, your actual result can swing wildly above or below that number in either direction. RTP is a statement about the game's design, tested and certified by independent labs like eCOGRA or iTech Labs, not a guarantee about any individual outcome.
House edge is the same coin, flipped
House edge is just RTP expressed from the casino's side: 100% minus RTP. A 96% RTP game has a 4% house edge, meaning the casino expects to keep 4% of all money wagered over the long run. Table games typically publish clearer, lower house edges than pokies — European roulette sits at 2.7%, blackjack played with correct basic strategy can fall below 1%, while the average online pokie sits somewhere between 3% and 5% (a 95–97% RTP range). This is one reason table games with correct strategy are often described as "better value" in the strict mathematical sense, even though pokies remain far more popular for their pace and jackpot potential.
Why volatility changes the experience
RTP tells you nothing about how a game distributes its payouts. A low-volatility pokie pays out smaller wins more frequently, keeping your balance relatively stable. A high-volatility pokie — the kind built around a big jackpot, like the network Kiwi's Treasure and several other operators run — pays out rarely, but the wins can be far larger when they land. Two pokies can both carry a 96% RTP and feel completely different to play: one grinds out small wins steadily, the other burns through your balance in long dry spells punctuated by occasional large hits. If your goal is a longer session on a fixed budget, a lower-volatility game with the same RTP will generally get you there.
How to actually use RTP when choosing a game
| RTP range | What it generally means |
|---|---|
| 97%+ | Above-average for pokies; look for this on games you plan to play at length |
| 95–96.9% | Typical range for most modern video pokies |
| Below 94% | Common for progressive jackpot games, where a cut funds the jackpot pool |
When a game's paytable or info screen discloses RTP (not all do, but most reputable studios now include it), use it as a comparison tool between similar games rather than a prediction tool for your session. Pairing a decent RTP with a volatility level that matches your bankroll and how long you want to play is a far more useful frame than chasing the single highest advertised percentage.
Frequently asked questions
Responsible gambling
RTP and house edge describe long-run averages, not a plan for tonight's budget. Set a session limit before you start, regardless of a game's advertised percentage — the math guarantees the house edge plays out over time, not that any single session behaves predictably.
