Rainbow King Slot Machine
The Rainbow King slot machine is well established as a favourite in UK casinos and also in mainland Europe. Interestingly, in Las Vegas, you would be hard pushed to find it anywhere — which is a real shame, because it's such a good game.
Rainbow King is a 5-reel, 20-payline slot machine from Novomatic. The game comes as a sequel to the highly popular Reel King. The vibrant release draws inspiration from a number of legends where rainbows were associated with great abundance and wealth — in Ireland, for instance, it was believed that leprechauns hid their pots of gold at the bottom of the rainbow. In Rainbow King, the main hero is the king who possesses an immense treasure he is more than willing to share with the luckiest players.
The main symbols on the reels include the Rainbow King himself, golden crowns, castles, pots of gold, and gemstones that all make up the high-value symbols. The regular playing card icons from 10 to King constitute the lower value icons on the grid.
The lucrative release boasts several bonus features, including the Rainbow King feature, Reel King feature, and King Cash Bonus.
The Rainbow King feature is triggered by spinning three Rainbow King symbols anywhere in view. Once in, you will play a kind of board game. When you press Start, the dice will start rolling. Should your dice land on a square containing a king symbol, a mini-slot game will be played where you can win Reel King spins. Additionally, landing on gemstones will reveal various cash rewards that can go up to 500x the bet.
Once you click Take the Money, you will return to the main game, or alternatively play the Reel King Bonus. Players that won the Reel King spins will be transported to a slightly altered set of reels featuring mostly lucky 7s. The game provides multiple chances for sizeable wins — however, be cautious since landing on any symbol other than a lucky seven will end the round.
When played at the highest bet available, the potential top prize is 500 coins, granted for lining up 3 lucky sevens during the Reel King spins. The King Cash feature is also rewarding, offering up to 500x your bet if you manage to pick a crown revealing the top prize.
One of the things people really love about Rainbow King slots is the way you get a harp sound when the reels spin — it's magical. The bonus features (there are three of them) on Rainbow King are great fun.

Frequently Asked Questions
What is the RTP of Rainbow King?
Rainbow King has an RTP (Return to Player) of approximately 95.1%, which is slightly below the current industry average of 96%. As a Novomatic sequel to Reel King with three distinct bonus features — the Rainbow King board game, Reel King spins and King Cash — its enduring popularity across European casinos speaks to the entertainment value despite the lower return rate.
Can Rainbow King be played for real money?
Yes, Rainbow King is available as a real money slot at online casinos and land-based venues in the UK and across Europe that carry Novomatic titles. Players in the USA currently cannot access Rainbow King for real money either online or in land-based casinos, though the free version is available to play worldwide.
How many paylines does Rainbow King have?
Rainbow King features 20 paylines on a classic 5-reel, 3-row grid. The paylines cannot be changed, meaning all 20 are active on every spin. The game uses a traditional left-to-right payline structure, with the three bonus features providing the most significant win opportunities beyond regular payline wins.
What are the bonus features in Rainbow King?
Rainbow King offers three bonus features. The Rainbow King feature is triggered by landing three Rainbow King symbols anywhere in view, launching a dice-based board game with cash prizes and entry to the Reel King spins. The Reel King Bonus plays on a separate set of reels filled with lucky 7s — landing anything other than a 7 ends the round. The King Cash Bonus is a pick feature where players reveal cash prizes up to 500x their bet.
How does the Rainbow King feature work?
Once triggered by three Rainbow King symbols, the dice-based board game begins. Each dice roll moves you around the board — landing on a king symbol activates a mini slot with Reel King spins, while landing on gemstone squares reveals instant cash rewards up to 500x your bet. Players can choose to Take the Money at any point or continue rolling for potentially larger prizes.
Can Rainbow King be played on mobile?
Yes, Rainbow King is available on mobile devices through Novomatic's platform. The harp sounds during reel spins, the board game feature and the Reel King bonus all translate well to smartphones and tablets, making it a convenient choice for real money play on the go in markets where it is available online.
