Rainbow King Slot Review

With a castle in the distance and a rainbow shining brightly above it, Novomatic’s Rainbow King mixes royalty with lots of colour – a combination which makes for a very exciting and fun filled slot machine that boasts a maximum win of £250,000!

This is actually a sequel to the Reel King slot machine from Novomatic and it is a substantial improvement on its predecessor which sees us enjoy fun symbols that are full of vibrant colours along with several different bonus features. While following a rainbow to the end wouldn’t result in a big pot of gold as the fiction goes, these bonus features never fail to line your pockets enabling you to live like a King – well for a little while at least!

We all like to win playing online slots, and the 95% return to player percentage on offer here gives us every chance. With 5 reels and 20 paylines, Rainbow King offers stake per line options from £0.01 up to £5 which will keep your bankroll management intact and enable you to play all paylines from £0.20 up to £100 every spin!

Rainbow Symbols and Sounds

The symbols in Rainbow King are quite simply awesome – they are so bright and colourful and really bring a fun factor to the reels. As with how most slots work, the Wild is the main symbol to watch out for as it substitutes for all others apart from the three bonus symbols (the King – who seems to have been designed in the style of Humpty Dumpty, Castle, and Crown) and pays out 25x should you land five on a payline. There is also a bag full of gold alongside playing card symbols Ace to 10 which each represent a colour from the rainbow.

The sounds help bring the slot to life with a magical tune playing as you spin the reels, and the sound of the castle door being knocked on as each one finishes spinning – a pleasant change from the standard Novomatic sounds they use in so many of their slots!

Cash Castle Feature

Landing three of more Castle symbols will see you enjoy a pick ‘em game which guarantees a win – that’s what we like to hear! You then select a castle of your choice at random and it will reveal the prize you have won, it really is that simple. The cash prizes on offer range from as little as 2x your total bet up to a maximum of 500x your total bet.

Rainbow King Feature

The Rainbow King feature is triggered by landing three or more King symbols anywhere on the reels and it is guaranteed to remind you of Monopoly Big Event from Barcrest. This is a board-game style feature that requires you to spin dice in order to navigate around the board, with each position offering various prizes. Your aim will be to keep landing on the Rainbow King position as this grants you access to the Reel King feature which plays out once you eventually land on the ‘take the money’ position of the board.

The Reel King feature sees you presented with a one reel slot machine which allows you to keep spinning until a symbol other than a 7 lands on the reel. The top prize here is 500 coins should you land three red 7’s.

King Cash Feature

King Cash is yet another pick ‘em game but hey that just means you are guaranteed a win, although I did find it to be the toughest to activate. This bonus feature kicks into action when you land a Crown symbol on reel 2, 3 and 4 during the same spin. You are then presented with a grid 12 different Crown’s to select from and the twelve prize values on the left. A minimum prize of 50x your total bet is up for grabs while the maximum is a king-size 500x!
