Rainbow King™ is a casino game for one player and falls into the category of slot machines. As soon as you enter a game you will start a so-called ‘session’ (or gaming session). Each session is a separate, completely independent game - earlier gaming sessions have no influence on your current gameplay. Each game basically starts when you place a bet and ends when you leave the application. Your current game session ends when you leave the application.

The following betting and payout rules are valid for the game:

  • RTP: 95.00%

  • Maximum bet per session: Your available credit on the player account. Making a deposit your player account is not possible during a session.

  • Minimum bet per round: 0.20 €

  • Maximum bet per round: 50 €

Here you can see the course of the win lines. You can display the win lines again after every round with the functions ‘Lines’ and ‘Bet/Line’.

Number of lines

1 to 20 win lines: You can decide before each round how many lines you want to play on.

Line wins

You can win when 2 identical symbols match.: Every line win starts on the first reel on the left and runs without interruption along the win line to the right.


‘Wild’ symbol: Substitutes represent other symbols and can complement line wins and help you to achieve a higher win. Each substitute can - when cutting through various win lines - act as a different symbol for each win line and therefore complement several line wins. Substitutes keep their appearance even when replacing other symbols.
