How the Game Plays

The King of Heroes is a medieval-themed slot developed by Booongo (distributed via 3 Oaks Gaming) that invites players into a realm of legends and warriors. Abandoning traditional paylines, the game uses a 6x4 grid with 4,096 ways to win, where matching symbols only need to land on adjacent reels starting from the leftmost side. The high-value symbols consist of four distinct heroes and a central King, while lower values are represented by standard card ranks.

Free Spins Explained

Landing three or more Castle Scatters triggers the Free Spins mode. This feature is more complex than a standard bonus round due to the introduction of a progress meter. During the spins, players aim to land Sun Artifact symbols, which are collected to fill the bar. Each time the meter reaches a milestone, the lowest-ranking hero symbol currently on the reels is permanently upgraded to a higher-paying character for the remainder of the session.

Hero Rise Feature Explained

The ultimate goal of the "Hero Rise" system is to transform every hero symbol into the top-tier King of Heroes. Every 10 Sun Artifacts collected results in a symbol upgrade and an additional free spin. If you successfully fill the entire meter, the reels become populated exclusively by the most valuable character and low-paying symbols, creating a high-potential environment for the maximum win of 5,000x.
