Do higher RTP slots hit more often or just return more overall?

A higher RTP widens the long-run payback but doesn’t change how often a slot lands a win. Hit frequency controls how many spins pay anything, while volatility influences the size and swinginess of those wins.

What’s the difference between volatility and hit frequency?

Hit frequency is the share of spins that result in any payout. Volatility explains how uneven those wins are — low variance means regular small hits, high variance means rare but chunky payouts.

Can casinos change the RTP offered to NZ players?

Some slots ship with multiple RTP settings. Licensed NZ-facing operators must select from the approved profiles, and the chosen percentage should appear in the paytable or help modal.

Do I need to bet max to win a jackpot?

Progressive jackpots often require the maximum stake to trigger the top prize, while fixed jackpots usually scale with your chosen bet size. Always skim the rules before spinning.

How big should my bankroll be for high-volatility games?

Plan on 100–200× your average stake for high-volatility pokies (e.g., NZ$2 spins → NZ$200–NZ$400). Lower-volatility titles can sometimes be played with 50–100× your stake.

Are online slots genuinely random?

Yes. Licensed slots are tested against certified RNG standards, so every spin is independent, unpredictable, and immune to player influence.

How many spins count as the “long run” for RTP?

RTP is calculated over millions of spins. Short sessions of a few hundred spins can swing wildly away from the advertised percentage.

How Slots Work: RTP, Volatility, Hit Rate, and RNG Explained

Pokies, or slots, use microchips and software to decide every spin before the reels even finish whirling. This guide breaks down the core mechanics so Kiwi players know exactly what drives the swings, the payouts, and the risks.

TL;DR

Every press of the spin button is settled instantly by an RNG; history never matters.

RTP advertises long-term maths (think millions of spins), not the results of a single night.

Volatility and hit frequency dictate whether you see lots of small wins or rare chunky ones.

As soon as you tap spin, the Random Number Generator picks symbol positions and stores the outcome. The reel animation simply reveals what was already decided, so you can’t time, influence, or predict the result.

Slots vs “Pokies” in New Zealand

New Zealanders usually say “pokies,” while international casino sites lean on “slots.” They describe the same machines. Both online and land-based pokies rely on audited RNGs, so the gameplay fundamentals and fairness checks align no matter where you play.

How Slots Work: Random Number Generators (RNG)

An RNG is a constantly running script that cycles through numbers thousands of times per second and maps those numbers to reel positions.

How it plays out:

The RNG keeps churning through numbers, even when the game sits idle.
Pressing spin captures a snapshot of numbers that correspond to each reel stop.
The reels animate purely for show — the outcome is already locked in.
The RNG resumes whirring away immediately for the next spin.

Remember:

Spins do not form streaks; each one is statistically independent.
The result is final at the instant you start the spin.
“Patterns” and timing tricks don’t work because odds refresh every spin.
Independent labs certify casino RNGs so neither operators nor players can alter the math.

RTP (Return to Player): What the Percentage Really Means

Return to Player measures how much of the total wagered money a slot gives back over a gigantic sample. Whatever isn’t returned becomes the operator’s edge.

95% RTP → around NZ$95 returned out of every NZ$100 staked long term.
98% RTP → roughly NZ$98 back and NZ$2 kept by the house.
A higher RTP improves expectations over time but cannot guarantee profit per session.

Example: Take a 96% RTP slot. Playing NZ$1 spins for 100,000 spins equals NZ$100,000 wagered, with the model expecting ~NZ$96,000 in payouts on that scale. Across only a few hundred spins you can easily outperform or undershoot that percentage because variance dominates.

Common ranges:

Venue type	Typical RTP window
Online slots	94–99%
Land-based pubs/clubs/casinos	often a little lower

Always open the paytable/help screen to confirm the version you’re playing, as some titles ship with multiple RTP profiles.

Paylines, Ways to Win, and Bonus Features

Paylines are pre-set pathways across the reels where matching symbols must land to create a win. Early pokies gave you a single straight line; modern releases stack dozens or even hundreds of crisscrossing lines.

Ways-to-win engines pay whenever qualifying symbols land on adjacent reels (e.g., 243 ways), regardless of the row they occupy.

Fixed paylines: every line is staked automatically each spin.
Selectable paylines: you choose how many lines to activate, affecting stake size.
All-ways pays: any matching combo from left to right counts.

Frequent bonus extras:

Free spins rounds
Multipliers that boost wins
Wilds, scatters, and expanding symbols
Pick’em/pick-and-win mini games
Feature buys (where allowed by the operator)

Volatility and Hit Frequency: Risk and Session Feel

Volatility (variance) gauges how uneven the payouts are.
Hit frequency shows how many spins result in any return at all.

Loose guidelines:

Low volatility: hit rate around 40–50%; short-lived bankroll dips and many small wins.
Medium volatility: hit rate near 30–40%; noticeable swings but still regular features.
High volatility: hit rate roughly 20–30%; win droughts punctuated by chunky payouts.

Volatility shapes how a session feels far more than RTP, so pick games that suit your appetite for swings.

Bankroll Variance: Simple Scenarios for Low vs High Volatility

Illustrations (not predictions):

Low volatility (NZ$0.50/spin, 400 spins)
- Likely outcome band: −NZ$40 to +NZ$20
- Bonuses arrive frequently but seldom blow up
Medium volatility (NZ$1/spin, 300 spins)
- Likely outcome band: −NZ$150 to +NZ$150
- Base-game hits slow down; features matter
High volatility (NZ$1/spin, 200 spins)
- Likely outcome band: often −NZ$200 with occasional +NZ$300–NZ$1,000 spikes

Denomination, Max Bet, and Jackpot Eligibility

Denomination sets the value of one credit (10c, NZ$1, etc.).
Max bet is the ceiling stake per spin.
Progressive jackpots sometimes insist on max bet for the top prize, while fixed jackpots scale directly with your stake.

Read the info screen for each slot so you know whether max bet is mandatory to unlock certain jackpots or bonus upgrades.

Common Myths vs Reality

“Hot” or “cold” machines
- Reality: RNG outcomes never reference previous results.
Time-of-day theories
- Reality: the RNG doesn’t care what the clock says.
Button-tap timing tricks
- Reality: the winning combination is locked in before the reels spin up.
“Slots are rigged”
- Reality: the house edge exists, but audited RNGs prevent tampering and individual-spin predictions.
