Rainbow King Review

Rainbow King is a 5 reels and 20 paylines slot game that comes from Novomatic’s catalogue. You will get to meet the king of the rainbow himself. The graphics are quite basic and the software providers tried to keep things as simple as possible so you won’t find any distracting animations. 

Underneath the apparent simplicity, Rainbow King offers quite a mix of lucrative features including two click and collect bonus rounds called The King Cash Feature and Cash Castle where spinners will get instant prizes and Rainbow King feature which involves a mini-game where various prizes await. 



  • Popular Theme
  • Great Features
  • Good Prizes



  • Better graphics would have been great
