RTP, or Return to Player, is the single most important number every pokies player should understand. It represents the theoretical percentage of all money wagered on a pokie that will be paid back to players over the game's lifetime.
If a pokie has an RTP of 96%, it means that for every A$100 wagered by all players combined over millions of spins, the game will return approximately A$96 in winnings. The remaining A$4 is the casino's profit margin (house edge).
| RTP Range | Rating | House Edge | Player Impact | Examples |
|---|---|---|---|---|
| 98-99%+ | Exceptional | 1-2% | Smallest long-term losses | Book of 99, Mega Joker, Blood Suckers |
| 96-97.99% | Above Average | 2-4% | Good value for players | Starburst, Thunderstruck II, Gonzo's Quest |
| 94-95.99% | Average | 4-6% | Standard industry range | Many modern video pokies |
| 91-93.99% | Below Average | 6-9% | Higher cost to play | Some branded pokies, newer releases |
| 88-90.99% | Low | 9-12% | Expensive -- avoid unless jackpot | Progressive jackpots (e.g., Mega Moolah) |
Let's put RTP in real dollar terms. If you wager A$500 total in a session (not your deposit, but total amount bet across all spins), here's your expected theoretical loss:
96% RTP: A$20 expected loss | 94% RTP: A$30 expected loss | 90% RTP: A$50 expected loss
That's why choosing high-RTP pokies matters -- over time, the difference between 96% and 90% RTP adds up to hundreds of dollars in additional losses.
The house edge is simply the inverse of RTP. If a pokie has 96% RTP, the house edge is 4%. This is the mathematical advantage the casino holds over players and is how casinos generate their revenue.
| Game | Typical House Edge | RTP Equivalent | Player Value |
|---|---|---|---|
| Blackjack (basic strategy) | 0.5-1% | 99-99.5% | Best odds in casino |
| Baccarat (banker) | 1.06% | 98.94% | Excellent value |
| European Roulette | 2.7% | 97.3% | Good value |
| Online Pokies (high RTP) | 2-4% | 96-98% | Good value |
| Online Pokies (average) | 4-6% | 94-96% | Standard |
| Australian Land-based Pokies | 8-15% | 85-92% | Poor value |
| Keno | 20-40% | 60-80% | Worst odds |
Online pokies typically offer significantly better odds than land-based pokies in Australian pubs and clubs. While NSW pokies legally must return at least 85%, most hover around 87-90% RTP. Online pokies from the same providers frequently offer 95-97% RTP -- a massive difference that saves players thousands of dollars over time. This is one of the strongest arguments for playing online.
While RTP tells you how much a pokie pays back over time, volatility (also called variance) tells you how it pays. Two pokies can have identical 96% RTPs but feel completely different to play because of their volatility levels.
Win frequency: High (every 3-5 spins)
Win size: Small (1-10x bet)
Bankroll impact: Gradual, steady decline
Best for: Small bankrolls, long sessions, casual play
Examples: Starburst, Blood Suckers, Jack Hammer
Low volatility pokies produce frequent small wins that keep your balance relatively stable. You'll rarely see dramatic swings in either direction. These are ideal for low deposit players who want to maximise play time.
Win frequency: Moderate (every 5-10 spins)
Win size: Mixed (5-50x bet)
Bankroll impact: Moderate swings
Best for: Most players, balanced experience
Examples: Gonzo's Quest, Book of Dead, Thunderstruck II
Medium volatility offers the best of both worlds -- reasonably frequent wins with the potential for decent payouts during bonus features. This is the most popular category and suitable for most players.
Win frequency: Low (every 15-30+ spins)
Win size: Large (50-10,000x+ bet)
Bankroll impact: Dramatic swings
Best for: Large bankrolls, high rollers, thrill seekers
Examples: Dead or Alive 2, Lil Devil, Tombstone RIP
High volatility pokies can go dozens of spins without a win, then deliver massive payouts during bonus rounds. You need a large enough bankroll to survive the dry spells. These games provide the most exciting moments but require patience and budget.
To illustrate how volatility affects your experience, here's a simulated comparison of three pokies, all with 96% RTP but different volatilities, played at A$1 per spin for 100 spins:
| Metric | Low Volatility | Medium Volatility | High Volatility |
|---|---|---|---|
| Starting balance | A$100 | A$100 | A$100 |
| Winning spins | ~35 of 100 | ~22 of 100 | ~12 of 100 |
| Typical ending balance | A$85-$105 | A$50-$150 | A$0-$300+ |
| Chance of going bust | ~5% | ~20% | ~45% |
| Chance of doubling up | ~8% | ~18% | ~25% |
| Biggest single win | ~A$10-$20 | ~A$30-$80 | ~A$100-$500+ |
Hit frequency is the percentage of spins that result in any winning combination. This metric is closely related to volatility but provides a more precise measure of how often you'll see coins added to your balance.
A "winning spin" in hit frequency terms is any spin that returns something, even if it's less than your bet. On a A$1 spin, a return of A$0.20 counts as a "hit" even though you've net-lost A$0.80. The profitable hit frequency (spins that return more than your bet) is significantly lower than the overall hit frequency. For a typical 96% RTP pokie with 30% hit frequency, only about 10-15% of spins are actually profitable.
Every online pokie outcome is determined by a Random Number Generator (RNG). Understanding how RNGs work is fundamental to understanding pokies and debunking common myths.
The RNG constantly generates random numbers -- typically between 0 and several billion -- at a rate of hundreds per second. This happens 24/7, whether anyone is playing the game or not. The numbers are generated using complex mathematical algorithms that produce statistically random sequences.
When you tap the spin button, the game captures the exact number the RNG produced at that precise millisecond. This number (or set of numbers) determines the outcome. Because the RNG cycles through numbers so rapidly, the timing of your button press is the only variable -- and it's essentially random because human reaction times cannot be precise to the millisecond.
The captured random number is mapped through the game's mathematical model (called a "par sheet") to determine which symbols land on which reel positions. Each possible outcome -- from a total loss to a maximum jackpot -- has a specific probability assigned to it. The random number simply selects which outcome occurs.
The spinning reels, animations, and sounds are purely visual entertainment. The outcome was determined the instant you pressed spin. The reel animation is just a dramatic presentation of a result that was already decided. This is important: nothing you see on screen during the spin affects the outcome.
To ensure fairness, RNGs are tested and certified by independent laboratories. These tests verify:
Major testing labs include eCOGRA (Isle of Man), iTech Labs (Australia), GLI (Global Laboratories International), and BMM Testlabs. All games at our recommended casinos like SkyCrown, Ricky Casino, and MyStake use certified, audited RNGs from licensed game providers.
Understanding the maths behind pokies payouts helps demystify the game. Here's a simplified look at how a pokie's payout structure is designed:
Every pokie has a mathematical model (sometimes called a "par sheet") that defines:
Imagine a simple 3-reel pokie with 20 stops per reel and the following symbol distribution:
| Symbol | Stops per Reel | Probability per Reel | 3-of-a-Kind Probability | Payout |
|---|---|---|---|---|
| Wild / 7 | 1 | 1/20 = 5% | 1/8,000 = 0.0125% | 200x |
| Bar | 2 | 2/20 = 10% | 8/8,000 = 0.1% | 50x |
| Cherry | 4 | 4/20 = 20% | 64/8,000 = 0.8% | 10x |
| Bell | 5 | 5/20 = 25% | 125/8,000 = 1.56% | 5x |
| Blank | 8 | 8/20 = 40% | 512/8,000 = 6.4% | 0x (loss) |
Total possible outcomes: 20 x 20 x 20 = 8,000. The expected return from this simplified model: (1/8000 x 200) + (8/8000 x 50) + (64/8000 x 10) + (125/8000 x 5) = 0.025 + 0.05 + 0.08 + 0.078 = 0.233, or 23.3%. A real pokie achieves 96% RTP by including many more symbol combinations, paylines, wilds, and bonus features.
A pokie's maximum win potential is inversely related to its win frequency. A game advertising 50,000x max win has allocated a large portion of its RTP budget to that extremely rare outcome. This means less RTP is available for regular wins, resulting in higher volatility. Games with lower max wins (500-2,000x) tend to distribute RTP more evenly across regular wins, creating a smoother playing experience.
Gambling is surrounded by myths and superstitions. Here are the most common pokies myths and the mathematical reality behind each:
REALITY: Every spin is independent. The RNG has no memory of previous outcomes. A pokie that hasn't paid in 100 spins has exactly the same chance of paying on spin 101 as it did on spin 1. This is known as the Gambler's Fallacy -- the incorrect belief that past outcomes influence future probabilities in random events.
REALITY: What appears to be hot/cold streaks is normal statistical variance. If you flip a coin 100 times, you'll often see runs of 5-7 heads in a row, even though each flip is 50/50. Pokies work the same way -- clusters of wins and losses are mathematically expected and do not indicate a pattern.
REALITY: For licensed online pokies, the RTP is set by the game provider and certified by independent labs. The casino cannot alter the RTP on a per-player or per-session basis. Some providers do offer multiple RTP configurations (e.g., 94% and 96%), but these are set server-side and apply to all players equally.
REALITY: On most modern online pokies, the RTP is the same regardless of bet size. The exception is some older pokies and progressive jackpots where maximum bets unlock additional paylines or jackpot eligibility. Always check the game rules to confirm.
REALITY: The RNG operates identically 24/7. There's no time of day, day of week, or season that affects pokies odds. The number of other players online also has zero impact on your individual spin outcomes (except for progressive jackpots, where more players means faster jackpot growth).
REALITY: This is conspiracy thinking with no evidence. RNGs don't know or care whether you're a new or returning player. The games deliver the same statistical outcomes regardless of account age. New players may perceive better luck because they're playing with bonus funds and more enthusiasm, leading to confirmation bias.
The house always has an edge. Over sufficient time and spins, the casino will retain the house edge percentage. Short-term results are unpredictable. You can absolutely win in any given session. Choosing higher RTP pokies reduces your expected losses. This is the only strategic advantage available to pokies players. Bankroll management extends your play time. Proper bet sizing is the most practical skill you can develop.
Now that you understand the theory, here's how to apply this knowledge to improve your pokies experience:
This is the single most impactful decision you can make. Playing a 97% RTP pokie instead of a 93% one saves you A$4 per A$100 wagered. Over a month of play, that difference can amount to hundreds of dollars. Our Best Pokies page lists the highest-RTP games available at Australian casinos.
If you have a small bankroll (under A$50), stick to low volatility pokies to extend your playing time. With A$100-$500, medium volatility gives the best balance. Only play high volatility games if you have A$500+ and can stomach losing streaks of 30+ spins. See our Low Deposit Pokies guide for specific game recommendations.
Calculate your expected hourly cost: (Bet Size) x (Spins Per Hour) x (House Edge) = Expected Hourly Loss. At A$1 per spin, 600 spins per hour, and 4% house edge: A$1 x 600 x 0.04 = A$24 expected hourly loss. Adjust your bet size so this figure falls within your entertainment budget.
Before spending real money, play pokies in free demo mode to experience their volatility and features. This costs nothing and gives you valuable insight into how a game "feels." Most casinos at our recommended list, including MadCasino and Aphrodite, offer free play on most pokies. See our Free Online Pokies guide.
Before each session, decide: "I'll stop if I lose A$X or win A$Y." This removes emotional decision-making from the equation. Many experienced players use a 50% loss limit (stop at half bankroll) and a 100-200% win target (stop after doubling or tripling).
Knowing a pokie's RTP is only useful if you can actually find the information. Here's where to look:
Most pokies display their RTP in the game's information/help section. Look for a menu icon (three lines or a question mark) within the game interface. Navigate to "Game Rules," "Info," or "Paytable," and scroll to find the RTP percentage. This shows the actual RTP configured at the specific casino you're playing at.
Providers like Pragmatic Play, NetEnt, and Play'n GO publish default RTPs on their official game pages. Note: the actual RTP at your casino may differ if the operator selected a different configuration. Always check in-game first.
Some casinos publish RTP lists for their entire game library. Check the footer links for "Game RTP," "Payout Rates," or similar pages. Casinos like Wino Casino and Tucán Casino provide transparency on their RTP settings.
Casino review sites (including ours) list RTPs for popular pokies. However, always verify against the in-game information, as the casino you're playing at may use a different RTP setting than what's listed on review sites.
Many game providers (including Pragmatic Play, the most popular provider at Australian casinos) offer their games in multiple RTP configurations. For example, a game might be available at 96.5%, 95.5%, 94.5%, or 87%. The casino chooses which version to offer. Always check the in-game RTP, not just the provider's default listing. If a casino refuses to disclose RTP information, that's a red flag.
RTP settings can vary between casinos for the same game. Here's how our recommended casinos compare in terms of RTP transparency and typical game configurations:
| Casino | RTP Transparency | Typical RTP Range | RTP Published? | Notes |
|---|---|---|---|---|
| SkyCrown | High | 94-97% | In-game | Generally uses higher RTP configs |
| Ricky Casino | High | 94-97% | In-game | Transparent RTP in game info |
| MadCasino | High | 94-97% | In-game | Good RTP across providers |
| MyStake | High | 94-97% | In-game | Large library with good RTPs |
| Donbet | High | 94-97% | In-game | Similar configs to MyStake |
| Aphrodite | Medium | 93-96% | In-game | Check individual games |
| Tucán Casino | Medium | 93-96% | In-game | Varies by provider |
| Casinonic | High | 94-97% | In-game | Generally player-friendly RTPs |
| Queenspins | High | 94-97% | In-game | Good variety of high-RTP games |

RTP stands for Return to Player and represents the theoretical percentage of all wagered money that a pokie will pay back to players over its lifetime. For example, a pokie with 96% RTP theoretically returns $96 for every $100 wagered over millions of spins. This is a long-term statistical average, not a guarantee for any individual session. Always choose pokies with 96%+ RTP for the best value.
A good RTP for online pokies is 96% or above. RTPs between 96-97% are considered above average, while anything above 97% is excellent. Some pokies like Blood Suckers (98%) and Book of 99 (99%) offer exceptionally high RTPs. Pokies below 94% are generally considered low RTP and should be approached with caution unless they are progressive jackpots where the lower base RTP funds the jackpot pool.
Licensed online pokies from reputable providers are not rigged. They use certified Random Number Generators (RNGs) that are regularly tested by independent auditing firms like eCOGRA, iTech Labs, and GLI. These audits verify that game outcomes are genuinely random and that actual RTPs match advertised figures. Always play at licensed casinos with games from established providers like those we recommend at FastPayPokies.
Volatility (or variance) describes the risk profile of a pokie. Low volatility pokies pay small wins frequently, providing steady gameplay suitable for smaller bankrolls. High volatility pokies pay larger wins but less frequently, creating dramatic swings in your balance. Medium volatility offers a balance between the two. Choose volatility based on your bankroll size and risk tolerance.
No, the house edge means that pokies are mathematically designed to favour the casino over the long run. A 96% RTP means the casino retains 4% of all money wagered over time. However, short-term results can vary dramatically -- players can and do have winning sessions, big bonus round wins, and even jackpot wins. The key is treating pokies as entertainment with a cost, not as an investment. Set limits and play within your budget.
What appears to be hot and cold streaks is actually normal statistical variance. Each spin is completely independent, determined by an RNG that has no memory of previous results. Humans are naturally prone to pattern recognition, so we perceive clusters of wins as "hot" and clusters of losses as "cold," but these are random fluctuations, not predictable patterns. No pokie is ever "due" for a win or a loss.
Many game providers offer their pokies in multiple RTP configurations. Casinos can choose which version to deploy. A game might be available at 96.5%, 95%, or 94% RTP. Casinos that choose lower RTPs earn more per spin but risk losing players to competitors offering higher RTPs. This is why it's important to check the in-game RTP at the specific casino you're playing at, not just the provider's default listing.
No. The RNG operates identically regardless of time, day, or how many other players are online. Pokies odds are hardcoded into the game's mathematical model and cannot change based on external factors. Playing at 3 AM gives you exactly the same odds as playing at 3 PM.
Understanding pokies maths makes one thing clear: the house always wins over time. Play pokies as entertainment, not as a way to make money. Set firm budgets and time limits. If you're struggling with gambling, call 1800 858 858 for 24/7 free support or visit our Responsible Gambling page.
