Every pokie has two numbers that tell you far more than its theme or its bonus features: its return to player (RTP) and its volatility. RTP tells you what the game costs on average; volatility tells you how bumpy the ride will be along the way. Most players have heard of RTP, fewer understand volatility, and very few know that the same game can run at different RTP settings on different sites. This guide explains all three in plain New Zealand dollars.
What RTP means
Return to player is the share of all money wagered on a game that it is designed to pay back over a very large number of plays. A pokie with a 96% RTP is designed to return NZ$96 for every NZ$100 wagered, in the long run, across all players.
The other side of RTP is the house edge: 100% minus the RTP. A 96% RTP game has a 4% house edge. That 4% is the price of playing, paid gradually on every bet.
Two things RTP does not mean:
- It does not describe your session. Over a few hundred spins, results swing widely above and below the average. RTP only shows itself over enormous numbers of spins.
- It does not mean you get 96% of your money back. It applies to every dollar wagered, including winnings you bet again. If you keep re-betting a balance, the edge applies to it again and again.
The number that actually matters: cost per hour
A more useful way to use RTP is to estimate what an hour of play is expected to cost:
Expected cost = stake per spin × spins per hour × house edge
For example, at NZ$1 a spin, 500 spins an hour and a 4% house edge, the expected cost is about NZ$20 an hour. At NZ$2 a spin it is about NZ$40. Double the speed of play and you double the cost again.
This is why fast games and features like turbo spin or autoplay matter: they do not change the edge, but they increase the number of bets per hour. The same arithmetic sits behind bonus wagering; our guide to what wagering requirements really cost applies it to bonus turnover.
What volatility means
Volatility (sometimes called variance) describes how a game’s payouts are spread out:
- Low-volatility games pay small wins often. Your balance moves in small steps, and sessions tend to last longer for the same budget.
- High-volatility games pay less often but include rare, much larger wins. Long losing runs are normal, and a budget can disappear quickly before a big win arrives — or without one arriving at all.
Two games can have exactly the same RTP and completely different volatility. Neither is better value; they are different experiences. Low volatility suits players who want longer sessions on a fixed budget. High volatility suits players who accept long dry spells for the chance of a larger hit.
Many game information panels show volatility on a scale, and some sites let you filter by it. If you are playing on a small budget, a lower-volatility game gives you more play for the same money.
Hit frequency is not the same thing
Some games also publish a hit frequency: how often a spin returns something. A high hit frequency can feel generous, but many of those “wins” return less than the stake. A spin that costs NZ$1 and pays NZ$0.40 counts as a hit while still losing you money. Judge a game by its RTP and volatility, not by how often it lights up.
The same game can have different RTP settings
This surprises many players. Game studios often release a pokie with several RTP settings, for example 96%, 94% and 92%, and each operator chooses which version to offer. The game looks identical; only the maths differs.
The difference is not small. Using the cost-per-hour formula, NZ$1 spins at 500 spins an hour cost about NZ$20 an hour at 96%, but about NZ$40 an hour at 92%. That is twice the cost for the same game.
The only reliable place to check is the game’s own information or help panel on the site where you are playing, not a studio’s marketing page or a review. If the panel does not show the RTP at all, treat that as a reason for caution. Our review methodology samples games on every profile to check that RTP is displayed and whether the standard setting is used.
Features that change the maths
- Bonus buy. Some games let you pay to enter the bonus round directly. Bonus buys often have their own RTP, and because each purchase is a large single bet, they increase the amount wagered quickly.
- Progressive jackpots. Part of each bet funds the jackpot, so the base game usually returns less. Our guide to how progressive jackpots work explains the trade-off.
- Ante bets and extra-chance modes. Paying more per spin for better bonus odds changes both the cost and, sometimes, the RTP.
Table games for comparison
Table games publish their rules, so their house edge can be calculated. Basic-strategy blackjack with standard rules has a much lower edge than most pokies, and single-zero roulette has roughly half the edge of double-zero roulette. Rules matter: small changes, such as a reduced blackjack payout, raise the cost noticeably.
Practical habits
- Check the RTP in the game’s own panel before you play, and prefer standard settings.
- Choose volatility for your budget: lower for longer sessions, higher only if you accept long losing runs.
- Estimate your cost per hour with the formula above, and set your budget from that.
- Slow down. Fewer spins per hour means lower expected cost, whatever the game.
- Set a deposit limit before you start; our player protection toolkit shows how.
The short version
RTP is the long-run price of a game; volatility is how uneven the ride is. A 96% game costs about 4% of everything you wager, and the number of bets you make per hour decides what that means in dollars. The same pokie can run at different RTP settings on different sites, so check the game’s own panel. Pick volatility to suit your budget, and never mistake frequent small “wins” for value.
Q: What does 96% RTP mean?
A: The game is designed to return NZ$96 of every NZ$100 wagered over a very large number of plays, across all players. The remaining 4% is the house edge, the average cost of playing. Individual sessions vary widely.
Q: Is a high-volatility pokie better value?
A: Not by itself. Volatility changes how wins are spread, not the long-run cost. A high-volatility and a low-volatility game with the same RTP cost the same on average, but the high-volatility one has longer losing runs and rarer, bigger wins.
Q: Why does the same pokie show different RTP on different sites?
A: Many studios release several RTP settings of the same game, and each operator chooses one. The version looks identical but costs more to play at a lower setting. Check the game’s own information panel on the site you use.
Q: How do I estimate what a pokies session will cost?
A: Multiply stake per spin by spins per hour by the house edge. At NZ$1 a spin, 500 spins an hour and a 4% edge, the expected cost is about NZ$20 an hour.

Highest payout casino games in New Zealand
If you want to minimise the house’s advantage across casino game types, not just pokies, here are the highest payout options ranked by house edge — from best to worst for the player:
| Game | House edge | Condition |
|---|---|---|
| Video poker — full-pay Jacks or Better | 0.46% | Optimal hold strategy required |
| Blackjack — basic strategy | 0.50% | Basic strategy card required |
| French roulette — La Partage rule | 1.35% | Even-money bets only |
| Baccarat — banker bet | 1.06% | Always bet banker; avoid tie |
| European roulette | 2.70% | Single zero only |
| Standard pokies (top providers) | 3–5% | Depends on RTP setting chosen by operator |
| American roulette | 5.26% | Double zero adds to house edge — avoid |
| Keno | 20–35% | Worst odds in the casino |
What “highest payout” actually means: a game with a lower house edge returns more to players over time. Jacks or Better video poker at 0.46% house edge returns 99.54 cents per dollar wagered in the long run — making it the highest-payout standard casino game available when played with correct strategy.
The catch with low house edge games: they require skill or strategy. Blackjack at basic strategy is different from blackjack played by guessing. Video poker at 0.46% house edge requires memorising the optimal hold decision for every hand. Players who deviate from optimal strategy give back much of the edge advantage.
For NZ pokies players: among pokie games, the highest paying options are typically those from major studios with published RTPs above 96%. NetEnt, Play’n GO and Pragmatic Play regularly publish certified RTPs; games from unknown developers often do not. Always check the game’s own information panel — a padlock icon or “i” button — for the RTP figure before playing.
Q: Which casino games have the highest payout percentage in New Zealand?
A: Video poker (full-pay Jacks or Better at 99.54% RTP) and blackjack with basic strategy (around 99.5% RTP) have the highest payout percentages of any standard casino game. Among pokies, games from major certified studios typically run 95–97% RTP. Keno and scratch cards have the lowest return to player.
Q: What is the highest RTP pokie available at NZ casinos?
A: RTP varies by operator because studios often offer multiple settings. Book of Dead (Play’n GO) and Legacy of Dead are commonly found at 96%+ settings. Ugga Bugga (Playtech) reaches over 99% RTP but is rarely available at NZ-facing casinos. Stick to games from certified studios that publish their RTP in the game information panel.
