What Is RTP (Return to Player)?

RTP stands for Return to Player. It is a percentage that represents how much of the total money wagered on a game is theoretically paid back to players over time. It is the single most important number for understanding how favourable a casino game is.

Here is a simple example: a pokie with 96% RTP is designed to return $96 for every $100 wagered, on average, over millions of spins. The remaining $4 (4%) is the casino’s profit margin, known as the house edge.

Key Points About RTP

  • It is a long-term average. RTP is calculated over millions or billions of simulated spins. It does not predict what will happen in your next session, your next hundred spins, or even your next thousand spins.
  • Higher is better for players. A 97% RTP game returns more to players than a 93% RTP game. The difference might seem small, but over thousands of spins it adds up significantly.
  • It includes all payouts. RTP factors in regular wins, bonus features, free spins, jackpots, and every other payout mechanism in the game.
  • It is set by the game provider. The RTP is programmed into the game’s mathematics by the developer (Pragmatic Play, Play’n GO, etc.) and cannot be altered by the casino mid-session.
For NZ players: RTP applies identically whether you play from Auckland, Wellington, or anywhere else. The game mathematics are the same regardless of your location. What can differ is which version of a game (with higher or lower RTP) your casino offers — more on that in the RTP versions section.

RTP and the House Edge

RTP and house edge are two sides of the same coin. Together they always equal 100%.

House Edge = 100% − RTP
A game with 96% RTP has a 4% house edge.
A game with 99% RTP has a 1% house edge.

The house edge is the casino’s mathematical advantage on every bet. It is how casinos make money. Every casino game has a house edge built in — there is no game where the odds are genuinely in the player’s favour over the long term (unless you are counting cards at blackjack, which is a different matter).

What This Means in Real Money

Let’s say you wager $10,000 in total bets during a session (not your deposit — your total bets, which recycle as you win and reinvest):

  • At 96% RTP (4% house edge): Expected loss = $400
  • At 97% RTP (3% house edge): Expected loss = $300
  • At 98% RTP (2% house edge): Expected loss = $200
  • At 99% RTP (1% house edge): Expected loss = $100

Each percentage point of RTP saves you $100 in expected losses per $10,000 wagered. For high-volume players, this adds up to thousands of dollars over time. Choosing high-RTP games is one of the few things you can do to mathematically improve your outcomes.

Variance & Volatility Explained

RTP tells you how much a game pays back. Variance (or volatility) tells you how it pays back. Two games can have identical RTPs but completely different playing experiences due to variance.

Low Variance / Low Volatility

  • Frequent small wins
  • Smoother, more predictable gameplay
  • Your balance fluctuates gently
  • Good for longer sessions on a set budget
  • Good for clearing wagering requirements
  • Examples: Starburst, Blood Suckers, Thunderstruck II

Medium Variance / Medium Volatility

  • Mix of small and medium wins
  • Balanced experience
  • Moderate balance fluctuation
  • Good all-round choice for most players
  • Examples: Gonzos Quest, Book of Dead, Fire Joker

High Variance / High Volatility

  • Rare but large wins
  • Long dry spells between payouts
  • Dramatic balance swings
  • Requires a larger bankroll to survive dry spells
  • Potential for massive multiplier wins
  • Examples: Wanted Dead or a Wild, Mental, Sweet Bonanza, Gates of Olympus

Choosing the right volatility: Match volatility to your bankroll and goals. If you have $50 to play with, a high-volatility pokie could eat through it in 20 spins with nothing to show. A low-volatility game with the same budget might give you an hour of entertainment. If you have a large bankroll and want the chance at a massive win, high volatility is the way to go.

RTP by Game Type

Different casino game categories have vastly different RTP ranges. Understanding these helps you make informed choices about where to spend your time and money at online casino sites in NZ.

Pokies (Online Slots)

RTP range: 88% to 99% (most fall between 94–97%)

Pokies have the widest RTP range of any casino game category. The best pokies approach table-game RTPs, while the worst have house edges of 10% or more. Always check the RTP before playing a pokie — the difference between a 94% and a 97% game is significant over any meaningful number of spins.

Blackjack

RTP: 99.0% to 99.7% (with basic strategy)

Blackjack offers the lowest house edge of any table game when played with basic strategy. The exact RTP depends on the specific rules (number of decks, dealer stands/hits on soft 17, etc.). Without basic strategy, the effective RTP drops to around 95–96%.

Roulette

RTP: 94.7% (American) to 97.3% (European)

Always play European roulette (single zero). American roulette (double zero) nearly doubles the house edge for no additional benefit. French roulette with La Partage rules offers an even better 98.65% RTP on even-money bets.

Baccarat

RTP: 98.76% (banker) to 98.94% (banker with no commission)

Baccarat is one of the best-value table games. The banker bet has the lowest house edge. Avoid the tie bet (RTP approximately 85.6%).

Live Dealer Games

Live dealer games have the same RTP as their standard counterparts. Live blackjack, live roulette, and live baccarat use the same rules and odds. Game show-style games (Crazy Time, Monopoly Live, etc.) have RTPs that vary by bet type, typically ranging from 92% to 96%.

Provably Fair Originals

Casino original games with provably fair mechanics often have very high RTPs because the casino profits from volume. Stake’s Dice game has 99% RTP, and their Crash game has approximately 99% RTP (varying slightly by auto-cashout settings). Learn more in our provably fair casinos guide.

How to Find RTP Information

Knowing a game’s RTP before you play is essential. Here are the best ways to find it.

1. In-Game Information

Most pokies display their RTP in the paytable or game info section. Look for a “?” or “i” icon, then navigate to the rules or paytable tab. The RTP is usually listed near the bottom. This is the most reliable source because it shows the actual RTP version your casino uses.

2. Game Provider Websites

Providers like Pragmatic Play, Play’n GO, and NetEnt publish RTP figures for all their games on their websites. Note: these may show the maximum RTP, which might differ from the version your casino offers.

3. Casino Game Lobby

Some casinos display RTP directly in their game lobby or search results. This is becoming more common as players demand transparency. Not all casinos do this yet.

4. Review Sites and Databases

Sites like CasinoGuru, SlotCatalog, and our own guides maintain databases of game RTPs. These are useful for comparing games before you play, but always cross-reference with the in-game figure.

Beware of reduced-RTP versions: Some casinos offer lower-RTP versions of popular pokies to increase their profits. A pokie listed as 96.5% on the provider’s website might be offered at 94.5% at certain casinos. Always check the in-game paytable to confirm the actual RTP at your specific casino.

Different RTP Versions — What Casinos Don’t Tell You

This is one of the most important and least-discussed topics in online casino gaming. Many players do not realise that the same pokie can have different RTPs at different casinos.

How It Works

Game providers like Pragmatic Play create multiple versions of each pokie with different RTPs. A game might be available in 96.50%, 95.50%, 94.50%, and even 87.00% versions. Casinos choose which version to offer based on how much they want to earn from that game.

Examples of Multi-Version RTPs

PokieMaximum RTPCommon Reduced RTPs
Sweet Bonanza96.51%95.45%, 94.50%, 91.37%
Gates of Olympus96.50%95.51%, 94.50%, 91.50%
The Dog House96.51%95.51%, 94.51%
Big Bass Bonanza96.71%95.67%, 94.68%

The difference between 96.50% and 91.37% is enormous. At 91.37% RTP, the house edge is 8.63% — more than triple the house edge at 96.50% (3.50%). For a player wagering $5,000, the expected loss increases from $175 to $432.

Which Casinos Offer the Best RTP Versions?

Reputable crypto casinos on our best online casino sites in New Zealand list generally offer the highest or near-highest RTP versions. Less reputable casinos — particularly those with extremely generous-sounding bonuses — often use reduced-RTP versions to compensate.

Always verify: Before playing any pokie, open the game, go to the paytable/info section, and check the stated RTP. If it is significantly lower than the figure on the provider’s website, the casino is using a reduced-RTP version. Consider playing at a different casino that offers the full-RTP version.

RTP Myths Debunked

There is a lot of misinformation about RTP in online gambling communities. Let’s set the record straight on the most common myths.

Myth 1: “A pokie is due to pay out because it hasn’t paid in a while”

False. This is the gambler’s fallacy. Every spin is independent. The random number generator (RNG) does not track previous results. A pokie that has not paid a bonus in 500 spins is no more likely to trigger one on the 501st spin than on any other spin. There is no “due” in mathematics.

Myth 2: “Casinos can change the RTP of a game while you’re playing”

False. Casinos cannot adjust the RTP mid-session. The RTP is baked into the game’s software by the provider. What casinos can do is choose which RTP version to offer when they first integrate the game. Once a version is selected, it stays constant for all players. If you open a game and it shows 96.50% RTP, it will remain 96.50% throughout your session.

Myth 3: “Playing at certain times of day gives better results”

False. RNG-based games produce truly random results regardless of the time, day, or how many other players are online. The game does not know or care what time it is in New Zealand.

Myth 4: “Higher bet sizes give better RTP”

Mostly false, with a few exceptions. For the vast majority of pokies, the RTP is identical at all bet sizes. However, a small number of classic pokies (like Mega Joker) have bonus features that are only accessible at maximum bet, meaning the maximum RTP requires max bet. These are exceptions, not the rule.

Myth 5: “New accounts get better RTP to lure you in”

False. RNG games treat all players identically. Your account age, deposit history, or VIP status does not affect game outcomes. The mathematics are the same for a brand-new player as for a veteran.

Myth 6: “RTP means I will get back 96% of my money”

Misleading. RTP is a long-term statistical average over millions of spins. In any individual session, you might win 300% of your deposit or lose it all. RTP tells you the theoretical expectation but guarantees nothing about your personal results.

Using RTP in Your Casino Strategy

Now that you understand RTP, here is how to use it practically as an NZ player.

For Casual Play

  • Choose pokies with 96%+ RTP as a baseline. Avoid anything below 95% unless you specifically enjoy the game and accept the higher cost.
  • Match volatility to your mood. Low volatility for relaxing sessions, high volatility when you want excitement.
  • Check the RTP in-game before playing, especially at casinos you have not used before.

For Bonus Wagering

  • Play the highest-RTP pokies that are not excluded from the bonus terms. Games like Blood Suckers (98.0%) and Book of 99 (99.0%) are ideal for wagering but are sometimes excluded precisely because of their high RTP.
  • Prefer low-to-medium volatility games for wagering. They drain your balance more slowly, giving you the best chance of completing the playthrough. See our wagering requirements guide for more strategies.

For High Rollers

  • Even a 1% RTP difference matters enormously at high stakes. If you wager $100,000 per month, the difference between 96% and 97% RTP is $1,000 in expected value.
  • Consider provably fair games with very high RTPs (Stake Dice at 99%) for volume play.
  • Table games (blackjack, baccarat) offer better RTPs than pokies for high rollers willing to learn basic strategy. See our high roller casino guide for table game limits.

For Everyone

  • Never choose a game based on RTP alone. A 99% RTP game you do not enjoy is a worse choice than a 96% RTP game you love. Gambling is entertainment, and enjoyment matters.
  • Use RTP as one factor alongside volatility, theme, bonus features, and your personal preferences.
  • Remember that no RTP guarantees a win. Always gamble responsibly and only with money you can afford to lose.

Frequently Asked Questions

  • RTP stands for Return to Player. It is a percentage showing how much a game theoretically returns to players over millions of spins. A 96% RTP means $96 is returned for every $100 wagered on average. The remaining 4% is the house edge. RTP does not guarantee short-term results.

  • 96% or higher is considered good. The industry average is 95–96%. RTPs above 97% are excellent. Some pokies like Blood Suckers (98.0%) and Book of 99 (99.0%) offer exceptionally high returns. Below 94% is considered below average.

  • They are two sides of the same coin. RTP + House Edge = 100%. If a game has 96% RTP, the house edge is 4%. Higher RTP means lower house edge, which is better for the player.

  • No. RTP is a long-term theoretical average. In any individual session, your results can deviate wildly. You might win big or lose everything regardless of the game’s RTP. It provides a statistical expectation, not a guarantee.

  • They mean the same thing in casino context. Low variance/volatility = frequent small wins. High variance/volatility = rare large wins. Both can have the same RTP but deliver very different playing experiences.

  • Check the in-game paytable or info section (most reliable), the game provider’s website, or casino review databases. Always verify the in-game figure, as casinos may use reduced-RTP versions of popular pokies.

  • Casinos cannot change RTP mid-session. However, providers often create multiple RTP versions (e.g., 96.5%, 95.5%, 94.5%) and casinos choose which to offer. Always check the in-game RTP to confirm which version you are playing.

  • Not necessarily, but they are transparent about their exact mathematics. Some provably fair originals like Stake Dice (99% RTP) do offer very high returns. The key advantage is that you can verify the fairness yourself rather than trusting an RNG audit certificate.

Responsible Gambling
Understanding RTP helps you make informed choices, but it does not eliminate risk. Every casino game has a house edge, and the house always wins in the long run. Set a budget, stick to it, and never gamble more than you can afford to lose.
