Rainbow King Slot Review

Rainbow King is a 5 reel 20 payline slot powered by Novomatic. You can play for as little as 20p a spin and as much as £100 a spin – this slot game caters to all kinds of players. Rainbow King only comes with a 500 coin jackpot but it more than compensates with the 3 superb bonus features.

Firstly, there is the Rainbow King Feature – you can trigger this by getting 3 or more King symbols in view. You need to then press the Spin button which will move you around the feature board (by throwing a dice). Each square you land on will have different prizes. When you land on a Rainbow King square, you will see a small slot game which you can play when your character lands on a ‘Take the Money’ square.

When landing on this square, the free spins will play out. The Reel King spins ends though when a symbol other than a ‘7’ appears on the reels. Look out for the red 7s because if you get 3, you will win 500 coins.

The next bonus round is the Cash Castle Feature which you activate by getting 3 or more castle symbols. This is a classic ‘Pick Me’ feature where you choose a castle to reveal your prize – you will get between 2 times and 500 times your bet.

The final bonus round is the King Cash Feature which you trigger by getting 3 Crown symbols on reels 2, 3 and 4. As another ‘Pick Me’ feature, you need to select 1 of the 12 crowns to reveal your prize. The King Cash Feature can be very lucrative with between 50 and 500 times your bet.

Rainbow King is a great slot game where you can win up to £250,000. It has an expected return of 95% which is good. When playing Rainbow King, we found the features hard to trigger but once in, the rewards were worth the wait. This is a land based classic and one I recommend you try. If you like Novomatic slots, I also suggest you try Lord of the Ocean (an absolute must!).
