RTP and volatility are the two most important numbers behind every online pokie. Here is what they actually mean for your bankroll.
RTP stands for Return to Player, and it is the single most important number associated with any online pokie. Expressed as a percentage, RTP represents the theoretical amount of money a pokie returns to players over an extremely large number of spins. If a pokie has an RTP of 96%, it means that for every $100 wagered, the game returns $96 on average and keeps $4 as the house edge.
Here is the critical thing to understand: RTP is a long-term statistical average calculated over millions of spins. It does not tell you what will happen in your next 100 spins, your next 1,000 spins, or even your next 10,000 spins. In any individual session, your actual return can be wildly different from the stated RTP — you might double your money, or you might lose it all. RTP only converges to its stated value over an enormous sample size.
For NZ players choosing where to play online pokies for real money, RTP should be a key factor in your game selection. A difference of even 1–2% in RTP has a meaningful impact on your expected returns over any extended period of play.
Let me walk you through a practical example that illustrates why RTP matters but does not predict individual sessions.
Imagine two pokies, both available at sites like Neospin:
If you wager $10,000 on each over the course of several months, your expected outcomes are:
That is a $500 difference in expected losses simply from choosing the higher-RTP game. Over a year of regular play, this adds up significantly.
Here is where it gets tricky. In a single session of 200 spins at $1 each ($200 wagered), your actual return could be anywhere from $0 to several thousand dollars depending on whether you hit bonus features or big wins. The 97% RTP does not mean you will get $194 back from that $200 session — that is not how variance works in practice.
RTP is useful as a tool for choosing which pokies to play, especially over repeated sessions. It is not a predictor of what will happen in any given session. This is where volatility comes in, and understanding both metrics together is essential.
Here are the RTPs of some of the most popular online pokies available to New Zealand players:
| Pokie | Provider | RTP | Volatility |
|---|---|---|---|
| Big Bass Bonanza | Pragmatic Play | 96.71% | High |
| Gates of Olympus | Pragmatic Play | 96.50% | High |
| Book of Dead | Play’n GO | 96.21% | High |
| Starburst | NetEnt | 96.09% | Low |
| Mega Moolah | Microgaming | 88.12% | Medium |
Volatility (also called variance) describes the pattern of how a pokie pays out. While RTP tells you how much a game returns over time, volatility tells you how it returns that money — in frequent small wins, or in rare large payouts.
Think of it this way: two pokies can both have a 96% RTP but feel completely different to play because of their volatility.
Both games return 96% over millions of spins, but the experience of playing them is dramatically different. Your choice between low and high volatility should depend on your bankroll, your risk tolerance, and what you find enjoyable.
Here is a detailed comparison of how the three main volatility levels differ in practice for NZ pokies players.
| Feature | Low Volatility | Medium Volatility | High Volatility |
|---|---|---|---|
| Win Frequency | High (every 3–5 spins) | Moderate (every 5–10 spins) | Low (every 10–20+ spins) |
| Win Size | Small (1–5x bet) | Mixed (2–50x bet) | Large (10–5,000x+ bet) |
| Bankroll Needed | Smaller ($50–$100) | Moderate ($100–$300) | Larger ($200–$500+) |
| Session Length | Long and steady | Moderate | Unpredictable |
| Best For | Casual players, bonus clearing | Balanced players | Thrill seekers, bigger bankrolls |
| Example Games | Starburst, Blood Suckers | Gonzo’s Quest, Wolf Gold | Book of Dead, Gates of Olympus |
Low volatility pokies are the steady performers. You will land winning combinations frequently, though the payouts tend to be modest — usually between 1x and 5x your bet. These games are excellent for players who want extended playing time on a smaller budget, or for anyone working through bonus wagering requirements where maintaining your balance is more important than hitting a huge win.
The downside is that the big-win potential is limited. You are unlikely to turn a $1 spin into a $5,000 payout on a low volatility pokie.
Medium volatility pokies strike a balance between frequency and size of wins. You will experience some dry spells, but they are shorter than with high volatility games, and the wins that do land can be meaningful without being life-changing. Most players find medium volatility pokies the most enjoyable all-around experience.
High volatility pokies are where the real drama happens. Long stretches of nothing, followed by a single spin that pays 200x, 500x, or even 5,000x+ your bet. Games like Gates of Olympus and Book of Dead fall into this category. They require a larger bankroll and stronger nerves, but they offer the highest ceiling for big wins.
RTP and volatility are independent metrics, and understanding how they interact is the key to making informed pokies choices. Here are the four possible combinations and what they mean for your play.
The safest combination. You lose less over time (high RTP) and experience stable, frequent wins (low volatility). These pokies are ideal for bonus clearing and extended casual play. Examples include Blood Suckers (98.00% RTP, low volatility) and Starmania (97.87%, low volatility).
You lose less over time, but individual sessions are unpredictable. When you win, you win big, but dry spells can be long and expensive. Big Bass Bonanza (96.71%, high volatility) fits this profile. These are excellent games for players with adequate bankrolls who want both good long-term value and big-win potential.
A slow bleed. You get frequent small wins, but the low RTP means you are losing more per dollar wagered over time. These games keep you playing for a long time but gradually drain your bankroll. Avoid these when better alternatives exist.
The worst combination for players. Infrequent wins and a higher house edge. Mega Moolah (88.12%, medium-high volatility) falls close to this category, though the progressive jackpot offsets the low base RTP for players specifically chasing the jackpot. For regular play without jackpot aspirations, avoid low-RTP, high-volatility games.
Now that you understand what RTP and volatility mean individually and together, here is how to apply that knowledge to choose pokies that match your specific playing situation.
Stick to low or medium volatility pokies with RTPs above 96%. Bet at the minimum level ($0.20–$0.50 per spin) to maximise your playing time. Games like Starburst and Thunderstruck II are solid choices. Your goal should be entertainment value per dollar rather than chasing big wins.
Choose low volatility, high RTP pokies to maintain your balance while working through wagering requirements. Blood Suckers (98.00% RTP) is a classic bonus-clearing choice. Always check that the game contributes 100% to wagering before you start. Read our pokies bonuses guide for bonus-specific strategies.
High volatility pokies are your domain, but bring an appropriate bankroll (200–300x your bet size minimum). Focus on titles with high RTP to offset the volatility. Gates of Olympus, Book of Dead, and Big Bass Bonanza are all proven performers in the high-volatility category.
Medium volatility pokies with 96%+ RTP offer the best of both worlds: reasonable win frequency with the occasional bigger hit. Games like Gonzo’s Quest, Wolf Gold, and Legacy of Dead fit this profile well.
Finding accurate RTP data for online pokies is not always straightforward. Here are the most reliable sources.
Most online pokies display their RTP in the game rules or paytable section. Look for a settings icon, an “i” (information) button, or a paytable link within the game interface. This is the most reliable source because it shows the RTP for that specific game instance.
Game providers like Pragmatic Play, NetEnt, and Play’n GO publish official RTP figures for their titles. Note that some providers offer multiple RTP configurations, and casinos can choose which version to offer. The in-game RTP always takes precedence over the provider’s default listing.
Some pokies sites display RTP information in their game descriptions. Neospin is notably good about this, offering RTP filtering tools that let you sort games by return percentage — a feature I wish more sites would adopt.
At DairyNZ Schools, we include RTP data in our game recommendations and reviews. Our high RTP pokies guide features a comprehensive list of the best-returning pokies available at NZ-friendly sites, with verified RTP data for each title.
There is a lot of misinformation about RTP and volatility circulating in pokies forums and social media. Let me set the record straight on the most common myths.
Reality: Every spin on an online pokie is determined by an independent random number generator. The game has no memory of previous spins. A pokie that has not paid out in 500 spins is no more likely to pay out on spin 501 than it was on spin 1. This is known as the gambler’s fallacy, and it is the most dangerous misconception in gambling.
Reality: Higher RTP means you will lose less on average over a very long period. In any individual session, anything can happen. A 96% RTP pokie can eat your entire bankroll in 20 minutes, and an 88% RTP pokie can pay you a massive jackpot. RTP is a long-term metric, not a session predictor.
Reality: RNG-based pokies produce random results regardless of the time of day, the number of players, or any other external factor. There is no “best time” to play pokies. The RTP and volatility are fixed properties of the game software.
Reality: Licensed and regulated casinos cannot alter a game’s RTP on the fly. RTP configurations are set when the game is installed and can only be changed through a regulated process that requires approval from the game provider and the licensing authority. Any mid-session manipulation would be illegal and grounds for licence revocation.
Reality: RTP applies to the total amount wagered, not deposited. If you deposit $100 and play through it multiple times, you might wager $500 or more in total. The RTP applies to that total wagered amount. This is why understanding bankroll management is just as important as understanding RTP — learn more in our how to play pokies guide.
