How Pokies Work: RTP, Volatility, Hit Frequency, and RNG Explained for Australians
Modern pokies are software-driven games that use certified math to decide every symbol stop. Whether you’re spinning at a suburban club or inside an online lobby, the internal logic of these Electronic Gaming Machines (EGMs) is identical. This walkthrough translates the behind-the-scenes mechanics into plain language so you know exactly what influences each session.
Key Takeaways
- Outcomes Lock Instantly: The RNG finalises your result the moment you press spin; anything you see afterward is just presentation.
- RTP Reflects Long-Term Averages: Numbers like 96% RTP describe millions of spins, not a single night’s outcome.
- Volatility Sets the Ride: Low volatility = lots of smaller hits, high volatility = fewer but chunkier payouts.
- Stay in Control: Establish limits before you play. Need help? Gambling Help Online is available at 1800 858 858 or https://www.gamblinghelponline.org.au
Pressing “Spin” captures a snapshot of the RNG’s current values and maps them to reel positions. The animation you watch is simply revealing a decision that was made in fractions of a second, guaranteeing a fair and unpredictable result.
”Pokies” vs. “Slots”: Any Difference?
Australians tend to say “pokies,” while the rest of the world sticks with “slots.”
The nickname dates to “poker machines,” the earliest cabinets that mimicked card poker. Even though tech has evolved to video and digital titles, the shortened term stuck with Aussie players.
| Australia & New Zealand | International |
|---|---|
| Pokies | Slots |
| Gaming Machine | Slot Machine |
| Pokie Room | Slot Floor |
No matter the label, both land-based cabinets and online titles rely on a Random Number Generator (RNG) to drive results.

The Engine Room: Random Number Generators (RNG)
The RNG is the core program that keeps pokies unpredictable.
How it works:
- The RNG loops through thousands of number sets every second.
- When you tap “Spin,” it freezes the exact batch active at that instant.
- Those numbers correspond to reel positions.
- The reels animate to reveal the outcome that was already decided.
- The RNG immediately restarts the loop for the next bet.
Need-to-knows:
- Independent Spins: Previous results never influence the next one.
- Instant Resolution: Your win or loss is determined before the reels stop.
- No Secret Patterns: “Hot” or “cold” machines are gambler myths.
- Certified Fairness: Third-party labs audit licenced RNGs to ensure no tampering.
Regulators require ongoing testing, so properly licenced venues can’t alter outcomes on the fly.
Understanding RTP (Return to Player)
Return to Player (RTP) is the percentage of staked money a pokie is expected to redistribute over an extended sample. Subtracting RTP from 100% gives the house edge.
- 95% RTP: The venue keeps about $5 per $100 wagered in the long haul.
- 98% RTP: The venue keeps around $2 per $100 over time.
- Reality Check: High RTP improves the math on paper, but short bursts are still governed by variance.
Example: Betting $1 for 100,000 spins on a 96% RTP pokie suggests $96,000 returned and $4,000 retained by the house. Over 200 spins, though, the range of outcomes is wide—you could hit a feature or burn through your balance quickly.
Typical RTP Ranges:
| Venue Type | Typical RTP |
|---|---|
| Online Pokies | 94–99% |
| Clubs | 87–92% |
| Pubs | 85–90% |
Always check the in-game info or paytable to confirm the exact percentage.
Paylines, Ways to Win, and Bonuses
Paylines are predefined routes across the reels where matching symbols must land to trigger a win. Early machines stuck to a single line, but video pokies often serve up dozens.
Ways-to-Win titles remove fixed lines altogether and pay for symbols landing on consecutive reels (think 243 or 117,649 ways).
- Fixed Lines: All lines are active and must be covered.
- Selectable Lines: You decide how many lines to pay for.
- All-Ways Games: Align symbols on successive reels for payouts.
Common extras:
- Free Spins: Extra rounds without deducting from your balance.
- Multipliers: Boost win values (2x, 3x, or higher).
- Wilds & Scatters: Special symbols that substitute or unlock bonuses.
- Pick Features: Choose objects on screen to reveal prizes.

Volatility vs. Hit Frequency
Volatility and hit frequency dictate the personality of each pokie.
- Volatility (Variance): Measures risk vs. reward by tracking win size and spacing.
- Hit Frequency: Shows how often any payout occurs across spins.
Rule of thumb:
- Low Volatility: 40–50% hit rates, steady drips of wins; ideal for smaller bankrolls.
- Medium Volatility: 30–40% hit rates, balanced swings.
- High Volatility: 20–30% hit rates, long droughts with occasional huge spikes; requires deeper pockets.
In short sessions, volatility will influence your balance swings far more than RTP.
Bankroll Scenarios
Here’s a simplified look at how volatility might impact your bankroll (illustrative only):
- Low Volatility (50c spins, ~400 rounds)
- Session Feel: Bankroll bounces between roughly -$40 and +$20.
- Outcome: Lots of features, but most are modest.
- Medium Volatility ($1 spins, ~300 rounds)
- Session Feel: Swings in the -$150 to +$150 range.
- Outcome: Fewer wins, yet bonuses hit harder.
- High Volatility ($1 spins, ~200 rounds)
- Session Feel: Balance may sag to -$200 before surging if a feature lands (+$300 to +$1,000).
- Outcome: Roller-coaster experience suited to thrill seekers.

- Max Bet: The ceiling on how much you can wager each spin.
- Jackpot Eligibility: Progressives may require max bets to unlock the top prize, while fixed jackpots usually scale with stake size.

Busting Pokie Myths
- Myth: Machines run “hot” or “cold.”
- Reality: Spins are standalone events; history doesn’t shift the odds.
- Myth: Time of day changes payouts.
- Reality: RNGs are time-agnostic and keep running around the clock.
- Myth: Stopping the reels early helps.
- Reality: The outcome was locked in already; manual stops are cosmetic.
- Myth: Online pokies are rigged.
- Reality: Certified titles undergo independent testing. The house edge delivers the casino’s profit, but each spin is still fair.
