The term signifies a mobile gaming application, specifically designed for the Android operating system, that allows players to progress and accumulate resources even when not actively playing. These games often feature mechanics that automate gameplay, generating rewards passively, and require minimal player interaction beyond initial setup and periodic upgrades.
The appeal lies in their accessibility and convenience. They provide entertainment during periods of limited availability and cater to players who prefer a more relaxed gaming experience. The genre has evolved from simple clicker games to more complex simulations with strategic elements and intricate progression systems, gaining significant popularity within the mobile gaming market.
