Fruit King Slot Review: 95.00% Return, No Published Cap

Fruit King Strengths and Weaknesses

Our 93-spin Demo Session, Counted

Read on 3 Nov 2026; the maker can change a screen without saying so.

What Fruit King Actually Is

Fruit King is a Greentube video slot with five reels, three rows and ten fixed win lines. The studio published it on its own site on 13 July 2021.

Its rules screen names two companies: Greentube Netherlands BV as manufacturer, Greentube GmbH as supplier. The client still carries the eurocoin INTERACTIVE mark, the earlier name of the Dutch studio. Above the reels, the logo reads "FRUIT KING! Cash Respin".

The name causes real confusion. Three games share it. Novomatic sells a land-based Fruit King for its CoolFire II-s cabinets, with free games and a volatility of 4 on its own scale. Greentube added a separate Fruit King Super Cash on 21 January 2025. Some catalogues mix them up, which is how this game picks up free spins, an expanding symbol and a line count it simply doesn't have in at least one listing.

Four bonus meters over the reels plus a coin that starts Cash Spins: that's the right game.

Cash Spins Carry the Game

Cash Spins carry Fruit King: the coin respin round is the game's only feature and the only route to its four fixed bonuses, topped by the 2,500x Grand. It is a respin round, not free spins on the reels.

Six coins start it. The coins lock in place, three Cash Spins are awarded, and any new coin that lands also locks and resets the count to three. The round ends when the spins run out or all fifteen positions hold a coin. Then the coins pay. Coins show 1x, 2x, 3x, 4x, 5x, 10x, 15x, 20x or 25x the bet. Some carry a Mini, Minor or Major label instead, worth 35x, 100x or 300x. Fill all fifteen positions and the 2,500x Grand Bonus lands on top.

We triggered it on the fourth spin. Six coins opened the round worth 70.00 between them on a 1.00 stake, with a full stack of jokers on reel three for company. Ten of the fifteen positions filled before the respins ran dry. The round paid 105.00, half as much again as the opening coins showed. Not bad for a first trigger.

The four bonuses are fixed amounts, not progressive pots: the meters read 2,500.00, 300.00, 100.00 and 35.00 on every frame of our session.

A 95.00% Return, Printed in the Game

Fruit King returns 95.00% (return to player) according to its own rules screen, while Greentube rates its volatility 5 on a scale it never defines.

Among Greentube's own surfaces, that figure lives in one place. Greentube's public game page sends readers to a client login for more data instead of printing a return. A reader who never loads the game never meets the number.

The game server is more candid than the web page. During the handshake it calls the build "Fruit King 95%", a name taken from its return figure. We saw only this one build, and whether casinos run other settings, the studio does not say. Any copy's rules screen prints the figure of the build it runs, so check it there.

Every Return Figure and Its Source

At 95.00%, the house keeps 5.00% of stakes over a very long run. On our 93.00 of stakes that comes to 4.65 in theory, a figure our session cheerfully ignored.

Volatility 5 Across 93 Spins

Ninety-three paid spins at 1.00 turned a 500.00 demo balance into 789.00, and two rounds did nearly all the work.

Only 14 of the 93 spins paid anything. Cash Spins brought 105.00, a single base-game spin paid 254.00, so those two made 359.00 of the 382.00 returned. The other twelve wins came to 23.00. Small change. In other words, the remaining 91 spins handed back 23.00 of the 91.00 they cost.

Twenty spins in, the balance read 587.00, almost all of it thanks to the coin round.

Honestly, a winning session proves little about a 95.00% game. Ninety-three spins is far too short a sample to say anything about the return. It is, however, a fair picture of volatility 5 in practice. Long runs of small wins, or of no wins at all, come first, and then one or two rounds turn up that decide the whole day, for better or worse. Run the same 93 spins again and the balance could just as easily finish under 500.00.

No Cap, Only Arithmetic

Fruit King has no published maximum win: the rules screen names no cap on a round, and Greentube's page is silent too.

The client's rules template can print a line that caps a round's winnings. In this build the server never sends that line.

Catalogues fill the gap. Freely. We found figures running from 1,000x to far beyond the 2,500x Grand, each one without a source.

Here is what the screens do support. Five sevens pay 125x the bet on one line, so sevens on all ten lines at once would come to 1,250x. In Cash Spins, fifteen coins at the top 25x make 375x. Add the 2,500x Grand and the total reaches 2,875x. Major labels on some of those coins would push it higher still, and the rules give odds for none of it. A ceiling can't be worked out from published data. That's the honest answer, and it's an unsatisfying one for anybody who came here hoping for a single tidy multiple to quote.

We do not recommend trusting any Fruit King max-win figure that hides where it came from.

Who Makes the Slot, on Paper

Greentube's British companies appear in the Gambling Commission register. Greentube GmbH holds account 41020 for gambling software, dated 16 March 2015. Greentube Alderney Limited holds account 39050 for remote casino, dated 1 November 2014.

Greentube Netherlands BV, the company the rules screen names as manufacturer, has no record of its own in the register files we downloaded on 28 October 2026. In Gibraltar, Greentube (Gibraltar) Ltd holds licence RGL No. 080. The Swedish register lists Greentube GmbH and Greentube Malta Limited among its holders.

Greentube Alderney paid the Commission £685,000 in December 2021 and £1,000,000 in January 2025 over social responsibility and anti-money-laundering failures. Neither case concerns this game, but a careful reader should know that record exists.

Before Fruit King Is Played for Money

Two checks come before any real-money spin on Fruit King. The first is whether online slots are legal where the reader lives; the second, whether the site sits on the local regulator's list of licensed operators. The answer differs from one country to the next, so check your local law first.

A licence number in a casino footer proves little until it matches the regulator's own register, company name included. Greentube's records above describe the supplier of the game. They say nothing about the website that loads it.

We do not recommend any website that offers Fruit King for real money without a licence number you can match in a public register. The free demo, which takes no money and pays none, shows the same paytable, all eighteen stakes and the Cash Spins round with nothing at risk.

If gambling stops being fun, Gambling Therapy gives free support to anyone, anywhere. Gamblers Anonymous holds meetings in person, online and by telephone, and BetBlocker blocks gambling sites on your own devices at no cost.
