Description of the slot machine

The original design and unusual opportunities will make you like the game. You can rarely meet the game in which there are four playing fields, with a very non-standard bonus round. In a further round, you can win up to 50 000 coins. Naturally, the winning combinations fall frequently, although the game has winnings of a large size. Finally, the developers at the Novomatic decided to change their principles and created a unique 4 Reel Kings slot machine.

The slot has an unusual bonus game. It's called the "Game of Kings." The bonus game is activated at random or when highlighting all the letters on the top of the screen. You will see one to five mini-slots. Each of them has three reels, and a winning combination creates coloured sevens. Three identical images bring up to 500 of the current rates. But the loss of character Rhombus is finishing the game in this mini-slot.
