Three reels and a 3x3 window, the fruit-machine shape behind Mega Joker, Jackpot 6000 and Fire Joker. Five classics compared on return, top win and how the Supermeter works.
Three Reels, Nine Symbols, Five Lines
A 3-reel slot is the shape of the original fruit machine: three spinning columns, usually with three symbols showing on each. All five games below use that 3×3 window with five fixed lines, the three rows plus two diagonals, so each spin shows nine symbols and five ways to line them up.
The small window keeps the action simple, and the studios add their twists around it: a second game tier on NetEnt’s classics, respins and multiplier wheels on Play’n GO’s Jokers. Games that pay on the rows alone are on our 3 payline slots page, and the wider grids on our 5 reel slots page.
Five Three-Reel Games and Their Numbers
Highest return first. For the two NetEnt games, the top figure applies only in Supermeter play, and the base game returns much less.
| Game | Studio | RTP | Max win | Volatility | Hit frequency |
|---|---|---|---|---|---|
| Mega Joker | NetEnt | Up to 99% | 200x + jackpot | – | 17% |
| Jackpot 6000 | NetEnt | Up to 98.9% | – | High | – |
| Fire Joker Freeze | Play’n GO | 96.18% | 1,000x | Medium | – |
| Fire Joker | Play’n GO | 96.15% | 800x | Medium | – |
| Break da Bank Retro Roller | Games Global | 95.75% | – | High | – |
Where a max win or volatility cell has a dash, listings disagree: Mega Joker is rated anywhere from medium to high, Jackpot 6000’s 6,000-coin top prize is quoted as 600x or 6,000x the stake, and Break da Bank Retro Roller’s ceiling appears as 500x or 480x. In the hit-frequency column, a dash means no figure is published.
Mega Joker
NetEnt’s most famous classic runs two games in one. Wins in the base game move into a Supermeter credit, where you play on at a higher stake, and a Joker on the middle reel there pays a mystery prize. NetEnt lists a 99% return, a 17% hit rate and a 200x top payout, with a progressive jackpot on top that can drop on any spin. The catch is that 99% needs the maximum stake and steady Supermeter play; a one-coin base game returns about 76.9%. Our Mega Joker guide covers the Supermeter in depth.
Jackpot 6000
Based on a Norwegian fruit machine called Jackpot 2000, this one follows the same Supermeter pattern. Supermeter play returns up to 98.9% against about 95% in the base game, and two jokers there award a random prize of up to 6,000 coins. There is no progressive jackpot. One listing puts the hit rate under one spin in ten, and most rate it high volatility.
Fire Joker Freeze
The 2021 follow-up adds ice to the fire. An Ice Joker brings its own respin alongside the Re-Spin of Fire, and the Wheel of Fire and Ice has four tiers, with a x20 multiplier at the top that lifts the ceiling to 1,000x. It returns 96.18% at its top setting, and casinos can choose versions as low as 84.18%.
Fire Joker
Play’n GO’s 2016 favourite keeps things tight. When the first two reels show matching stacked symbols without a win, the third reel respins for a second chance, and a grid full of one symbol spins the Wheel of Multipliers for x2 to x10. Nine Jokers with the x10 multiplier pay the 800x maximum. There are no free spins and no bonus buy. Our Fire Joker guide walks through the respin in detail.
Break da Bank Retro Roller
Games Global’s 2023 throwback strips everything back: five lines and no bonus round. The top return is 95.75%, with versions at 93.79% and 92%, and most listings call it high volatility. One listing puts its hit rate at about 24%. More pared-back reel sets are on our classic and retro slots page.
How a Supermeter Lifts the Return
The Supermeter is why two simple-looking NetEnt games carry some of the highest returns of any slot. A base-game win can be collected or carried up into the Supermeter, where the stake is higher and the paytable more generous. The more of your play happens up there at full stake, the closer the return gets to the headline figure.
The reverse also holds. Playing Mega Joker on one coin and collecting every win keeps you near the 76.9% base return, which costs far more over an hour than any of the Play’n GO games.
Why Nine Squares Pay Less Often
With only nine symbols on screen, a winning spin is rarer than on a 5×3 grid. Mega Joker’s 17% means about one win in six spins, and Jackpot 6000 can go ten spins or more between wins. The respins on the Fire Joker games exist partly to soften those gaps.
None of these games has anything to buy into. GB versions of slots carry no bonus buy in any case, and every wheel, respin and Supermeter run here comes from normal spins.
Fire Joker’s Five Versions
Fire Joker comes in five versions: 96.15%, 94.23%, 91.51%, 87.25% and 84.26%. At the £5 limit for players aged 25 and over, 600 spins an hour average about £116 on the top version and £472 on the lowest. At the £2 limit for players aged 18 to 24, that is roughly £46 against £189.
The game looks and plays the same in every version, so the only way to know which one a casino runs is the RTP line in the game’s help screen. Real sessions can land well above or below these averages.
