ONI Games · Published
Idle action RPGs for fans of Legend of Slime and Idle Slayer: auto-fighting heroes, runners and monster armies, with installs, rating, ads and offline support for each.
Legend of Slime and Idle Slayer are two of the most popular idle action RPGs on Android. In Legend of Slime you grow a slime and its army through endless battles; in Idle Slayer your hero runs and slays automatically while you jump for coins. Both turn a simple action into hours of upgrades. These ten games share that feel.
