4 Reel Kings by Greentube is a four-reel slot with 20 paylines, a low volatility profile, and an RTP of 94%. The game uses a 4x3 layout with a mix of fruit icons, card symbols, and crown-themed graphics. Bet settings range from 0.2 to 100, with autoplay, paytable, and gamble controls shown in the interface.

The main special feature is the Reel King bonus, where up to five Reel King characters can appear and award a series of prizes worth between 5x and 500x the total bet.
