What Is Mega Joker by Novomatic?

Mega Joker by Novomatic is a classic fruit machine developed by Greentube — the online division of the Novomatic Group — and released on 2 December 2013. The game translates the look and feel of a traditional European land-based cabinet into an HTML5 online slot: five reels, a 5×4 layout, 40 fixed paylines, and a symbol set built entirely around the joker/fruit machine aesthetic that Novomatic built its land-based reputation on. It is available both as a physical cabinet and as an online slot across Greentube-powered casinos.

One critical point before going further: this is not the NetEnt Mega Joker. The NetEnt title of the same name is a 3-reel, 5-payline game with a 99% RTP in its Supermeter mode — a structurally and mathematically different product. The Novomatic/Greentube version reviewed here runs at 95.05% RTP with low-to-medium volatility across 40 paylines. Searches for “Mega Joker slot” frequently surface both products simultaneously; this review covers the Novomatic/Greentube version exclusively. If the casino you are playing at lists the game as produced by Greentube, you are on the correct version.

The game’s theme is rooted in the classic joker / fruit machine aesthetic: cherries, lemons, oranges, plums, grapes, watermelons, strawberries, and the 77 symbol all sit on the reels alongside the Joker wild and the Star scatter. There is no elaborate narrative or animated bonus room — the design prioritises the mechanical clarity of a fruit machine with the accessibility of a modern HTML5 build, functional across desktop and mobile.

Game Facts at a Glance

Mega Joker Symbols and Paytable

The Mega Joker paytable is structured around a classic fruit machine hierarchy: a scatter at the top, a wild just below it, a premium non-fruit symbol, and then a descending tier of fruit symbols. All payouts below are expressed as multipliers of the total bet for the maximum five-of-a-kind combination, unless stated otherwise.

Fruit Symbols

The fruit symbol tier covers six distinct symbols across two payout bands. Strawberry and Pear both pay 6× the total bet for five on a payline — the highest-value fruit symbols on the reels. Grapes and Watermelon sit in the second band, each paying 4× for five on a payline. At the base of the paytable, landing five of any mixed fruit combination — an across-symbol line of different fruits — still awards 2.5×. This mixed-fruit payout is relatively unusual in fruit machine design and is a primary driver of the game’s 20% hit frequency, sustaining session momentum during sequences where premium symbol alignment doesn’t occur.

Joker Icon

The Joker is the wild symbol in Mega Joker. It substitutes for all standard pay symbols on the reels to complete winning combinations, and it is also the second-highest individual payer in the game: five Jokers on a payline pay 50× the total bet. The 77 symbol — a pair of lucky sevens — sits directly below the Joker in the hierarchy at 10× for five, providing a mid-range anchor between the Joker’s ceiling and the fruit symbol band. The Joker does not substitute for the Star scatter.

Reading the Paytable

Mega Joker uses 40 fixed paylines across its 5×4 grid — paylines cannot be adjusted, which means every spin costs the full 40-line stake. Wins are paid for matching symbols landing from left to right on a payline, with the exception of the Star scatter, which pays anywhere on the reels regardless of payline position. Because paylines are fixed, bet size is the only variable the player controls: the minimum spin costs €0.02 and the maximum costs €120, with all payout multipliers scaling proportionally. The 2.5× mixed fruit payout is the primary engine behind the 20% hit frequency — it fires on a much wider range of outcomes than any single-symbol combination.

Bonus Features and Special Mechanics

Mega Joker by Novomatic is a classic-format game, and its feature set reflects that philosophy: no free spins rounds, no expanding wilds, no pick-me screens. The mechanics it does offer — the Gamble feature, the Joker wild, and the Star scatter — are executed cleanly. One common point of confusion: the “Supermeter mode” associated with the Mega Joker name belongs exclusively to the NetEnt version of the game. In the Novomatic/Greentube build, there is no separate Supermeter reel set — the game plays on a single 5×4 grid throughout, with the Gamble feature as the primary post-win decision mechanic.

Gamble Feature

Mega Joker includes a Risk/Gamble (Double) feature that activates after any winning spin. The mechanic is a double-or-nothing proposition: the player is presented with a choice — typically a card suit or colour guess — and a correct answer doubles the win, while an incorrect answer forfeits it entirely. The gamble can be played multiple times in succession on an accumulated win, and the decision is entirely optional; players can collect their win at any point. For classic slot players accustomed to this mechanic from land-based play, the feature preserves the familiar tension of the cabinet experience in the online version. For sessions focused on bankroll management, the practical rule is to skip the gamble on any win above 10× the base spin cost — the compounding loss risk outweighs the upside on larger amounts.

Jackpot

The base version of Mega Joker by Novomatic does not include a progressive jackpot. The maximum win is a fixed ×2,000 multiplier relative to the total bet — delivered by five Star scatters anywhere on the reels at maximum bet, that translates to a top nominal win of €240,000 at the €120 ceiling stake. The IMPERA LINK and GOLDEN LINK variants of the game (covered below) incorporate linked progressive jackpot systems on top of the base game mechanics, but in the standard Mega Joker online slot the jackpot exposure is fixed and fully transparent.

RTP and Volatility Explained

The published 95.05% RTP is Greentube’s baseline figure for Mega Joker. This places it competitively within the classic slot category — the genre routinely runs between 94% and 96%, and 95.05% is a solid return for a low-to-medium volatility game. One practical caveat: Greentube lists an RTP range for this title, meaning individual casino operators may configure a reduced variant. Before playing for real money, open the in-game information panel — the RTP shown there is the one governing your actual session.

A direct comparison worth making explicit: the NetEnt Mega Joker advertises a 99% RTP in its Supermeter elevated-play state. That figure applies to a different product in a specific mode and is not a fair comparison with the Novomatic version’s 95.05% baseline. Players specifically pursuing maximum theoretical return should be clear on which developer’s game they are loading.

The low-to-medium volatility rating and 20% hit frequency define Mega Joker as a session-sustaining game rather than a jackpot hunt. Roughly one in every five spins returns something — primarily the 2.5× mixed-fruit payout — which keeps bankrolls moving at a controlled pace. Players should expect frequent modest returns interspersed with occasional Joker or Star activations, rather than prolonged cold runs followed by a single outsized event. A bankroll of 100–200× the base spin cost provides comfortable session exposure without material variance risk at the lower stake levels.

How to Play Mega Joker by Novomatic

Step-by-Step Guide

Mega Joker is deliberately straightforward to operate. The control layout follows standard Novomatic/Greentube conventions, with bet adjustment and spin controls clearly positioned below the reel grid.

1. Set the bet size. Use the bet controls to select your per-spin stake. The minimum is €0.02 and the maximum is €120. All 40 paylines are always active — there is no option to reduce the number of lines, so the selected bet covers the full grid on every spin.

2. Spin the reels. Press the spin button or activate autoplay for a predetermined number of spins. The reels resolve across the 5×4 grid, with wins credited for matching combinations on the active paylines from left to right, and for five Stars appearing anywhere.

3. Evaluate the win. If a winning combination lands, the win amount is displayed and the Gamble feature becomes available.

4. Decide on the Gamble feature. Choose to collect the win directly, or activate the Risk/Double mechanic to attempt to double it. The gamble option can be used repeatedly on accumulated wins, but each round carries the same binary outcome: double or forfeit.

5. Continue or cash out. After collecting, the next spin begins at the same stake level. There is no escalating play mode to opt into in this version — the session continues uniformly until the player stops.

Bet Sizes and Stakes

The €0.02–€120 bet range covers an unusually wide spread for a classic slot released in 2013. At the lower end, the €0.02 minimum is genuinely accessible for demo-transitioning players or those running extended sessions on limited budgets. At the upper end, the €120 maximum makes the ×2,000 max win worth €240,000 in nominal terms — though reaching that outcome requires a five-Star scatter event, which is a low-probability occurrence at any stake level.

Because all 40 paylines are fixed, increasing the bet proportionally increases both potential payouts and the monetary impact of the 20% hit frequency. A player at €0.20 per spin with a 20% hit rate expects a return event roughly every 5 spins; the size of that return scales directly with the stake. This linearity makes Mega Joker straightforward to bankroll — there are no bet-level thresholds that unlock different mechanics or change the game’s mathematical behaviour.

Play Mega Joker for Free – Demo Version

[DEMO EMBED WIDGET — insert Greentube Mega Joker demo iframe or platform plugin here]

The demo version of Mega Joker by Novomatic is the most practical first step before any real-money session — particularly for players new to classic fruit machine formats, where the absence of a free spins round means the base game mechanics carry the entire session experience. In demo mode, the Gamble feature, scatter payouts, and Joker wild substitution all function identically to the real-money version. No real-money winnings can be awarded in free play.

The primary value of demo play in Mega Joker is calibrating expectations around the hit frequency distribution. The 20% hit rate is frequent in absolute terms, but the size distribution of those hits — predominantly 2.5× mixed-fruit returns at the base — means the session experience is one of gradual credit movement rather than spike wins. Running twenty to thirty demo spins gives a realistic sense of how bankroll moves before any Joker or Star activation arrives. Ready to play for real money?

IMPERA LINK™ Mega Joker and Other Variants

Novomatic has extended the Mega Joker brand into two additional products listed separately in the Greentube catalogue: IMPERA LINK Mega Joker and GOLDEN LINK Mega Bonus Joker. Both retain the core fruit machine aesthetic of the original but layer a linked progressive jackpot system on top of the base game — the primary differentiator from the standard online slot reviewed here.

The IMPERA LINK system is Novomatic’s proprietary multi-level progressive network, where a portion of every bet across all connected machines contributes to shared jackpot pools. Machines are physically or digitally linked, and the jackpot can be triggered during regular play rather than through a dedicated bonus round — this is what distinguishes link-jackpot formats from standard progressives. The GOLDEN LINK system follows a similar architecture, with the Mega Bonus Joker variant applying it specifically to the Mega Joker symbol set and paytable structure.

The trade-off with both progressive variants is standard: a portion of each bet funds the jackpot contribution, which typically reduces the effective base-game RTP below the 95.05% figure of the standard version. Players who prioritise session sustainability and known return rates are better served by the base Mega Joker slot. Those willing to accept a lower expected return in exchange for jackpot exposure should look to the IMPERA LINK or GOLDEN LINK versions specifically — both are available at land-based Novomatic cabinets and at select Greentube online casino partners.
