King Kong Cash slot review

King Kong Cash slot: the short version

King Kong Cash comes from Blueprint Gaming, a UK studio based in Newark that is owned by Merkur Group. It is one of the games Blueprint is best known for, alongside Fishin' Frenzy and Eye of Horus.

The format is a traditional 5×3 grid with 20 paylines. What keeps it lively is the stream of random extras: modifiers that can appear on any spin and a bonus wheel with five possible outcomes. That variety is the main reason to choose it.

The trade-off is price. At 95.79%, the RTP is below many of the slots in our mobile slot reviews, so each pound staked costs a little more on average. If value per spin matters most to you, there are cheaper options.

King Kong Cash RTP and game specifications

UK operators must give players the rules of a game and information about the likelihood of winning, under the Commission's RTS 3 standard on game rules (opens in a new tab). That is where to look for the RTP and top prize in your app's version.

How the features work in King Kong Cash

The wild

The wild substitutes for every symbol except the scatter, helping to complete line wins across the 20 paylines.

Random base-game features

On any base-game spin, the game can randomly trigger one of several features. Two examples are Banana Cannon Wilds, which turns random symbols wild, and Bonus Boost, which adds extra scatters to the reels. These are random events, so there is no way to make them happen more often.

The bonus wheel

Landing three or more Kong bonus symbols starts a wheel, and the wheel picks which of five bonuses you play. The five possible bonuses are:

• A barrel-picking game.
• Golden Kong Free Spins.
• Empire Free Spins.
• A cash trail.
• The Big Monkey Bonus.

The wheel's result is random, and each bonus pays differently. The precise rules for each one, including how many spins or picks it gives, are in the in-game help pages.

What a 95.79% RTP costs compared with other slots

A difference of a percentage point or so in RTP sounds tiny, but it adds up over time. The table compares the expected cost per £100 staked for King Kong Cash and three other games on our site, using each developer's published top RTP.

For a £20 budget the numbers are small: at 10p a spin you get 200 spins, and the expected loss on that £20 of stakes is about £0.84. Over an hour of 600 spins at 50p, though, £300 is staked and the expected cost rises to about £12.63. At £1 a spin over the same hour it would be £25.26.

These are averages over huge numbers of spins. Your session will not land on the average, but the edge always works against you in the long run. Our house edge glossary entry explains why.

Playing King Kong Cash on a phone or tablet

Blueprint's games run in the browser engine inside casino apps, so King Kong Cash plays on iPhone, iPad and Android without its own download. The game sits in the casino's lobby; you open it like any other title.

A 5×3 grid is easy on the eye, though the bonus wheel and picking game have more going on visually. The developer information does not say whether portrait mode is supported, so rotate your phone if the wheel looks squeezed. See landscape vs portrait in casino apps for what to expect.

1. Log in to a UK-licensed casino app that has finished checking your age and identity.
2. Type King Kong Cash into the game search.
3. Before spinning, open the paytable to see the RTP, the five bonuses and the top prize.
4. Choose a stake within your budget; UK rules cap it at £5, or £2 if you are 18 to 24.
5. Tap to spin each time and keep an eye on the net spend and time display.

A weak signal during a bonus round can be unsettling. Our guide on what happens to a bet if your app crashes explains what to check and who to contact if a game is interrupted.

UK rules that apply to King Kong Cash

King Kong Cash in a UK app is not quite the same experience as older versions. Since 31 October 2021 British slots have had no autoplay, at least 2.5 seconds per spin, no turbo or slam-stop and no fanfare for returns that do not beat your stake. Since 17 January 2025 your net spend and time played are shown in real time.

Stake caps of £5 per spin (25 and over) and £2 per spin (18 to 24) also apply; the Commission's stake limit guidance (opens in a new tab) explains how they work within one game cycle. Our page on slot stake limits on mobile puts it in plain terms, and the autoplay ban page covers the history.

Since a Gambling Commission warning in January 2020, feature buy-ins are not offered to British players, so the bonus wheel is reached only by landing three Kong symbols.

Blueprint Gaming: the UK studio behind King Kong Cash

Blueprint Gaming was founded in 2001 and is headquartered in Newark, England. Merkur Group, formerly the Gauselmann Group, took an equity stake in 2008 and full ownership in 2012. It holds a UK Gambling Commission licence.

Beyond its own titles, Blueprint licenses the Megaways mechanic for games such as Ted Megaways and runs the Jackpot King progressive jackpot used across many of its slots. Whether a particular King Kong game is linked to a jackpot is shown in its own rules.

Slots like King Kong Cash

If you like the mix of random modifiers and a variety of bonuses, these titles on our site are worth a look. Fishin' Frenzy is another Blueprint staple with a slightly higher RTP, and Buffalo King Megaways offers an animal theme with high volatility.

Setting a King Kong Cash budget you are comfortable with

Random features firing on any spin can make a game feel like something is always about to happen. That is part of the design, and it is a good reason to set your limits before you start rather than during play.

• Set a deposit limit in the app and treat it as the cost of the evening's entertainment.
• Use a time-out if you want a break of a day or more.
• If you want a longer break from all UK gambling sites, GAMSTOP (opens in a new tab) lets you self-exclude for 6 months, 1 year or 5 years.
• The National Gambling Helpline, 0808 8020 133, is free, confidential and open 24/7.
