An online pokie is a piece of software that shows you spinning reels, but the result of every spin is decided in a split second by a random number generator (RNG) – a program that produces unpredictable numbers continuously. When you press spin, the game takes the number the RNG has just produced, maps it to a set of symbol positions, and then animates the reels to land on that already-decided outcome. Nothing about the reels spinning actually changes the result; the maths behind it does. This guide walks through each part a Kiwi player sees – reels, symbols, paylines, the RNG, return to player (RTP), volatility and bonus features – and explains how New Zealand’s rules keep licensed pokies fair.
What is an online pokie?
“Pokie” is the New Zealand and Australian word for a slot machine or slot game. An online pokie is the digital version you play in a web browser or a casino app, usually built by a specialist game studio and hosted by the casino. You choose a stake, press spin, and the game pays out when certain symbols line up.
Unlike a card game such as how to play blackjack, where your decisions change the odds, a pokie needs no skill or strategy to play. Every outcome is down to chance. That is also what separates a pokie from a live casino game, where a real dealer and physical equipment produce the result in front of you on a video stream.
Reels, rows and symbols
The grid you see is made of reels (the vertical columns that appear to spin) and rows (the horizontal lines of symbols). A classic pokie has three reels; most modern video pokies use five reels and three rows, though six- and seven-reel layouts are common too.
Each reel is a strip of symbols. Beyond the ordinary paying symbols, you will meet a few special ones:
- Wild: substitutes for most other symbols to help complete a win, a bit like a joker in cards.
- Scatter: pays or triggers a feature no matter where it lands on the grid, rather than needing to sit on a particular line.
- Bonus symbol: launches a mini-game, free spins or a jackpot round when enough of them appear.
Paylines and ways to win
A payline is a path across the reels along which matching symbols must land to pay. A line can run straight across the middle, along the top or bottom, or zig-zag diagonally. A win is counted when a run of matching symbols sits on an active payline, usually starting from the leftmost reel.
Fixed and adjustable paylines
Some pokies have fixed paylines: every line is always active and your stake covers all of them. Others let you switch lines on or off, so your total bet is the line stake multiplied by the number of active lines. The key point for a beginner is that the number on screen labelled “bet” is usually your whole stake for the spin, not the amount on a single line.
Ways to win and Megaways
Many newer pokies drop fixed lines in favour of a “ways to win” model. On a five-reel, three-row game, any matching symbols on adjacent reels pay, regardless of the row they sit in; with three symbol positions on each of the five reels, that works out to 3x3x3x3x3 = 243 ways to win. The Megaways pokies engine takes this further by changing the number of symbols on each reel every spin, producing up to 117,649 ways to win. More ways does not mean better odds on its own – the payouts are balanced to match.
How the RNG decides every spin
The RNG is the heart of a pokie. It runs continuously in the background whether or not anyone is playing. The instant you press spin, the game reads the most recent number and converts it into symbol positions for each reel. Because the number was produced before the reels finished moving, the outcome is already set – the animation is just presentation.
This has two consequences that trip up a lot of players:
- Every spin is independent. The RNG has no memory. A result has exactly the same chance of appearing whether the last spin was a big win or a hundredth straight loss.
- A pokie is never “due”. There is no cycle that makes a machine owe you a win after a cold streak, and no pattern of five spins or any other number that forces a payout. The odds are identical on every single spin.
To make sure the RNG really is random and the published payout figures are honest, licensed games are examined by independent testing laboratories. Agencies such as eCOGRA review the game’s source code, run large statistical samples and certify that the RNG is unpredictable and unbiased before the game goes live, then monitor it over time. A reputable casino will only host games that have passed this kind of testing.
RTP: what “96% return to player” means
Return to player (RTP) is the share of all money wagered that a pokie is designed to pay back over the very long run – across millions of spins by everyone who plays it. A game with a 96% RTP returns about NZ$96 for every NZ$100 staked on average over that huge sample. The missing portion, here 4%, is the house edge: the built-in mathematical advantage that lets the casino profit over time.
The trap is reading RTP as a promise for your session. It is not. Over an afternoon you could lose your whole balance or hit a big win; RTP only describes the average once the numbers get astronomically large. Think of a pokie’s cost as the house edge slowly applied to everything you stake, not as a 96% refund on your deposit. For comparison, skill-based machine games such as video poker can advertise higher RTPs, but only if the player makes the mathematically correct decisions.
Volatility: why two 96% pokies feel different
Two pokies can share the same RTP yet play completely differently, because of volatility (also called variance). Volatility describes how the returns are distributed – whether a game pays small amounts often or large amounts rarely. RTP tells you the long-run average; volatility tells you how bumpy the ride is on the way there.
Pokie volatility compared
| Volatility | How often wins land | Typical win size | Balance swings | Might suit |
|---|---|---|---|---|
| Low | Often | Small (a few times your stake) | Gentle | Players who want longer sessions on a set budget |
| Medium | Moderate | Mixed | Moderate | Most mainstream pokies and casual players |
| High | Rarely | Large (up to hundreds or thousands of times the stake) | Sharp, with long dry spells | Players chasing big-win potential who accept a fast-draining balance |
Neither type is “better”; they simply suit different budgets and tastes. Low volatility stretches a set bankroll across more spins, while high volatility risks a fast-draining balance in exchange for the chance of an occasional large hit.
Bonus features, free spins and jackpots
Most of the excitement in modern pokies comes from extra features layered on top of the base game:
- Free spins: a set of spins you do not pay for, often triggered by scatters and sometimes carrying extra wilds or multipliers.
- Multipliers: increase the value of a win by a stated figure, such as 2x or 10x.
- Pick-and-click rounds: a mini-game where you choose from hidden objects to reveal prizes.
- Jackpots: a fixed jackpot pays a set top prize, while a progressive jackpot grows as a slice of every bet across many players is added to a shared pool until someone wins it.
Features are still governed by the RNG, so they cannot be forced or predicted. One thing to check in the game’s info screen: some jackpots or features only unlock at a minimum stake or require the maximum bet to qualify.
Are online pokies fair and legal in New Zealand?
Fairness comes from two things working together: the independent RNG and RTP testing described above, and regulation that forces licensed operators to use tested games. New Zealand’s framework for this changed in 2026.
The Online Casino Gambling Act 2026 came into force on 1 May 2026 and, for the first time, creates a domestic licensing system run by the Department of Internal Affairs (DIA). Up to 15 licences will be issued, each covering a single casino brand. Operators that were already serving New Zealanders may continue until 1 December 2026; from that date, only licensed operators (or those with an application under consideration) may lawfully offer online casino gambling to people in New Zealand. Licensed casinos must meet safety standards designed to keep games fair and secure, will appear on a public DIA register, and must display a unique registration icon.
The DIA’s own advice to players is blunt: if you decide to use an unlicensed platform, you won’t have the same player protections. The practical risk for a Kiwi who plays on an unlicensed, offshore site is a loss of those protections – there is no local recourse if a game is not independently tested or a withdrawal is refused. Checking a casino’s licence and its payout policies, such as the terms set out on pages about the RiverBelle casino and similar brands, is the simplest safeguard.
Responsible gambling
Online pokies are games of chance, not a way to make money. The house edge means the longer you play, the more likely you are to be behind, and no system, stake size or spin count can change the odds on the next spin. Treat any money you stake as the cost of entertainment, set a deposit and time limit before you start, and never chase losses. If gambling is causing harm to you or someone you know, free, confidential help is available from the Gambling Helpline on 0800 654 655 or by texting 8006, any time of day, and through the Government’s Safer Gambling Aotearoa service. You can also use the responsible gambling tools most licensed casinos provide, such as deposit limits and self-exclusion.

Frequently asked questions
Are online pokies programmed to pay out at certain times?
No. Every spin is produced independently by the random number generator, which has no memory of past results. A pokie is never “due” to pay after a losing run, and it cannot be set to hit at a particular time of day or after a set number of spins.
What are my chances of winning on a pokie?
They depend on the individual game’s design and are never published as a simple percentage per spin. What is published is the RTP, a long-run average that still leaves a house edge, and the volatility, which tells you how often wins tend to land. The outcome of any single spin is impossible to predict.
Does the five-spin rule work?
No. The idea that you should leave a machine if it has not paid within five spins is a myth. Because each spin is independent and the odds never change, moving on after five spins has no effect on your chances – it is simply a way to pace yourself.
Does it matter how much you bet?
Your stake does not change the RTP or the chance of a given symbol landing. It does change the size of your wins and losses, so higher stakes mean bigger swings. Check the game info, though: some progressive jackpots and features only qualify at a minimum or maximum bet.
