Types of Online Slots
Not all slots are created equal. Just Casino’s library spans every major slot format — from simple 3-reel classics to complex Megaways engines with hundreds of thousands of paylines. Here’s your complete guide to every type available.
Classic 3-Reel Slots
The original slot format — three reels, simple paylines, and iconic fruit symbols (cherries, lemons, bells, sevens). Straightforward gameplay with fast rounds, low volatility, and nostalgic appeal. Perfect for beginners or players who prefer simplicity.
Video Slots (5-Reel)
Five reels, multiple paylines (from 10 to 1,024+), cinematic themes, animated bonus rounds, scatter symbols, wilds, and free spins. This is the dominant slot format — the vast majority of Just Casino’s library. Themes range from ancient mythology to sci-fi, horror, sport, and Kiwi culture.
Megaways Slots
Developed by Big Time Gaming, Megaways uses a dynamic reel modifier where the number of symbols per reel changes on every spin — creating up to 117,649 ways to win. Known for enormous win potential and high volatility. Hugely popular with NZ players who chase big multipliers.
Cluster Pays Slots
Forget paylines — cluster pays slots reward you for landing groups of identical symbols that touch horizontally or vertically. Often feature cascading/tumbling reels where winning symbols disappear and are replaced, creating chain reactions. Medium to high volatility with satisfying combo potential.
Progressive Jackpot Slots
A portion of every bet contributes to a growing jackpot pool — sometimes reaching millions of NZD. Can be triggered randomly or via special bonus rounds. Progressive jackpots include local (one casino), networked (multiple casinos), and daily must-drop jackpots with guaranteed daily payouts.
Live Game Shows
Evolution Gaming’s hybrid format — not traditional slots, but spinning wheel games broadcast live with real hosts. Features giant multipliers, bonus rounds, and interactive elements. Titles like Crazy Time, Dream Catcher, and Monopoly Live blend slot mechanics with live entertainment.
Cascading / Tumbling Reels
After a winning combination, the winning symbols disappear and are replaced by new ones falling from above — potentially triggering another win, then another, creating chain reactions. Often combined with increasing multipliers on consecutive wins. Found in both cluster pays and payline formats.
Buy Bonus Slots
A feature found in many modern Pragmatic Play and Nolimit City slots — for a set cost (usually 50–100x your bet), you can purchase the free spins round directly without waiting to trigger it naturally. Controversial but beloved by high-volatility players who want instant access to the big-win potential.
Infinity Reels™
ReelPlay’s patented mechanic — the grid starts at 3 reels and expands by one reel with each consecutive win. In theory, the grid could keep growing infinitely, with a growing multiplier attached. Delivers the highest potential max wins in slots format, often reaching 100,000x or more.

RTP & Volatility Explained
Two numbers that define your slot experience. Understanding RTP and volatility helps you choose the right game for your budget, goals, and risk appetite.
RTP is the percentage of all wagered money a slot pays back to players over millions of spins. A slot with 96% RTP returns NZ$96 for every NZ$100 wagered — theoretically. It’s calculated over millions of spins and does not predict individual session outcomes.
Always look for slots with 96% RTP or higher — the industry average is 95-96%. Slots below 94% significantly disadvantage the player over time.
Under 94% — Avoid
94–95.9% — Acceptable
96–96.9% — Good
97%+ — Excellent
Volatility describes how a slot distributes its wins — not how much it pays out overall, but the pattern and size of payouts. It’s the single biggest factor in your gaming experience.
Frequent small wins. Bankroll stays relatively stable. Good for beginners and players with small budgets. Examples: Starburst, Blood Suckers.
Balanced mix of small and big wins. Good for most players. Examples: Wolf Gold, Immortal Romance, Twin Spin.
Long dry spells but massive potential wins. Requires a bigger bankroll and patience. Examples: Bonanza, Gates of Olympus, San Quentin.
Jackpot Slots at Just Casino
The biggest wins in online gambling come from jackpot slots. Just Casino offers three categories of jackpot games — each with a different prize structure and win mechanic.
Must-Drop Jackpots
Must-drop jackpots are guaranteed to pay out by a specific time or amount. Hourly jackpots, daily jackpots, and “must-go” jackpots ensure prize pools can’t grow indefinitely. More frequent wins but smaller amounts. Perfect for players who find standard progressives too slow.
Fixed Jackpots
Fixed (or local) jackpots have a predetermined prize that doesn’t change. Typically triggered by landing a specific combination during a bonus round. Smaller than progressive jackpots but hit far more frequently. Mini, minor, major, and grand tiers are common in games like Wolf Gold and Mustang Gold.
Progressive jackpot slots often display a base RTP (e.g., 88%) that excludes the jackpot contribution. The “full” RTP including jackpot probability is higher — but the jackpot portion is extremely rare. Always check whether the displayed RTP includes the jackpot contribution before playing.
How to Play Online Slots
From complete beginner to understanding every mechanic — everything you need to know about playing pokies at Just Casino NZ.
The Basics
Browse by category (new releases, top rated, jackpots, Megaways) or use the search bar. Check the RTP and volatility in the game info panel before loading.
Use the + / – buttons to adjust coin size and number of active lines. Most modern slots use a single “total bet” slider. Set a bet that allows at least 100–200 spins within your budget.
Every slot has a paytable (usually accessed via ℹ or ≡). It shows symbol values, payline patterns, bonus trigger requirements, and special feature rules. 2 minutes reading it saves confusion later.
Press Spin for manual play, or set Autoplay for a chosen number of spins. Autoplay often has stop conditions — set a loss limit or stop on any win to maintain control.
Wins are credited automatically after each spin. When you’re ready to cash out, head to the Cashier, request a withdrawal, and funds arrive within 24 hours.

Slots Tips & Strategy
Online slots use certified RNGs — every spin is independent. There’s no “system” that beats the house edge. But smart decisions about game selection, bet sizing, and bankroll management can significantly improve your session experience.
Choose High-RTP Games
Always check RTP before playing. A 97% RTP game returns significantly more over time than a 94% game. The difference compounds fast — over 1,000 spins, a 3% RTP gap means NZ$30 per NZ$1,000 wagered.
Manage Your Bankroll
Never bet more than 1–2% of your session budget per spin. On a NZ$100 session, keep bets at NZ$0.50–2.00. This gives enough spins for natural variance to play out and bonus features to trigger.
Use Free Spins Wisely
Just Casino’s welcome bonus includes 300 free spins. Use them on high-volatility games during the bonus — a single big win can cover the entire wagering requirement. Check which games are eligible for free spin use.
Match Volatility to Budget
Small budget? Play low-medium volatility for more frequent wins and longer sessions. Large budget? High-volatility Megaways and extreme volatility games offer the biggest jackpot potential — but require patience through long dry spells.
Set Win & Loss Limits
Decide before you play: “I’ll stop if I lose NZ$50 or if I win NZ$150.” Slots are volatile — big wins can disappear in minutes if you keep playing. Locking in a profit by stopping protects your winnings.
Understand Random Number Generators
Every spin result is determined by a certified RNG — completely random, independent of previous spins. Slots have no “hot” or “cold” streaks. A slot that hasn’t paid out in 1,000 spins is no more likely to pay on spin 1,001. This is called the Gambler’s Fallacy — avoid it.
Responsible Gambling Reminder: Slots are games of chance. No strategy guarantees a win. Only gamble with money you can afford to lose, and always set limits before you play. If gambling stops feeling fun, use Just Casino’s responsible gambling tools or call the Problem Gambling Foundation NZ on 0800 664 262.
