King of the King Theme/Symbols

With a Muay Thai theme, King of the Ring tells the story on an intense combat between 2 Muay Thai fighters. With an Asian feel, symbols include A, K, Q, J, 10 and 9 royals as well as champion belts, mongkhon headbands, boxing gloves and the 2 Muay Thai fighters. The latter 2 pay 83.33 times your stake for 5 in combination.

There’s also another Muay Thai fighter symbol which is the wild and substitutes for all symbols bar the scatter – 2, 3, 4 or 5 on a payline will result in a 1.11, 22.22, 222.22 or 1,111.11 times stake win. You form winnings by getting matching symbols on adjacent reels starting from reel 1.

Free Spins feature

The King of the Ring slot comes with a solitary bonus feature – the Free Spins feature. This is played when you get 3 or more fighter scatters anywhere on the reels – you’ll get 2, 5, 20 or 500 times your stake for 2, 3, 4 or 5 on the reels. 3 or more will give you 15 free spins. With all wins subject to a trebling (3x) multiplier, you can retrigger the feature and win yourself another 15 free spins – taking your total to 30.

King of the Ring verdict

King of the Ring is rather basic in terms of gameplay as it just comes with 1 bonus feature found in countless other online slots. However, the Free Spins feature is a good one due to the high value symbols and the 3x multiplier. Filling the reels with Muay Thai fighter wilds will result in a 10,000 times stake payout – if you add in the 3x multiplier, you could potentially win 30,000 times your stake on every free spin! It is highly volatile though.

The King of the Ring mechanic may seem familiar – that’s because it uses the same game engine used in Microgaming’s iconic Thunderstruck slot. Not a bad slot to base yourself on! If you like the fighter theme though, Playtech’s Eliminators is recommended.
