Rainbow King is a colourful fantasy-themed video slot by Novomatic, built on a 5x3 grid with 20 adjustable paylines and a cast of regal symbols including castles, crowns, gems and the Humpty Dumpty-esque king himself. The game is a sequel to the classic Reel King slot and packs three distinct bonus features — Cash Castle, King Cash, and the Rainbow King board game — each triggered by landing 3+ of their respective scatter symbols. With low volatility and a wide betting range, it appeals to casual players seeking frequent bonus triggers and steady entertainment.
Rainbow King has an RTP of 95%, which is 1.10% below the industry average of 96.1%.
With low volatility, wins come frequently but tend to be smaller — ideal for players who prefer steady gameplay with lower bankroll variance.
* RTP is a theoretical long-term return percentage. Individual session results vary significantly.
