Game info


If you remember the Reel King by Novomatic, say hello to its sequel: free online Rainbow King slot machine. It comes with 3 exciting bonus features and still uses a theme of magic & medieval. This is a “tiny” casino game with lots of features packed and offers something for every kind of player out there. For newbies, we as usual repeat that all games including the Rainbow King slot machine are available for free and with no download, no registration required, just pick the game you like and start play for fun. This slot is similar to Roaring Forties.

How to Win?

The free Rainbow King slot machine is a classic one; it comes with 5 reels and 20 pay lines. Each reel contains 3 slots, and the number of pay lines can be adjusted. The game uses a mix of high-valued and low-valued symbols, and they are 11 in total. The highest valued ones are shown with theme related pictures, such as the king, the castle, and bags full of gold coins. The low-valued ones are shown with numbers and letters, as usual. You need to land 3 to 5 same symbols on a pay line to win prizes.

Bonus Features of the Game

Considering all the abilities of this slot machine, there are 3 bonus rounds in total:

  • Rainbow King Feature: You can activate this circle by getting 3 “King” symbols. The lap consists of a mini board entertainment, which you can move around by throwing a dice. Each square you land contains a different cash prize. If you manage to land on the “Rainbow King” square, a series of free spins get triggered. These free spins last until you get different signs than red 7’s on the reels. The maximum prize you can win during this round is 500 coins.
  • Cash Castle Feature: You can activate it by getting 3 “Castle” signs. This is also a mini-game, which asks you to pick between castle pictures. Each selection will reveal a different cash prize, and it is possible to win 500 x total bet during this round.
  • King Cash Feature:  Try to Stir up it by gaining 3 “Crown” characters. This is also a “pick me” mini-game, which you get to pick between crown features. You can gain 500 x total bet during this “performance”.

Bonus Features & symbols

There is no wild symbol in the game, but two different scatter symbols are available. “Castle” and “Crown” are used for scatter, and their purpose is to activate bonus rounds, as we explained above.

Minimal and Maximal Bets

The betting range is fairly small: it is possible to bet between 0.01 and 20 coins, per line. 250.000 coins are the maximum cash prize you can get. You can play it freely or for real money, the choice is up to you.

Where to Play?

The USA, UK, Canada, European Union, New Zealand, Australia and South Africa players can enjoy the game without restrictions. However, Turkish players are prohibited from playing the Rainbow King slot machine in online mode.

Chances to Win

The online Rainbow King slot comes with an RTP value of %95.00. This is not a particularly good number, but it is also not bad.  You will get most of your investments back in the long run, even if you can’t get anything.

Tips & Tricks

It is not necessary to play with maximum bet amounts; the highest prizes are only available during the bonus rounds. Since they get activated by scatter symbols, it is possible to play with minimum bet amounts and still get the “bigger” prizes.
