Idle games, also known as incremental games, became popular on mobile due to their simple mechanics and addictive nature. In these games, players start with minimal resources and gradually accumulate more over time, often without needing to actively play. Auto Play is a key mechanic in idle games, allowing the game to progress even when the player is offline. This mechanic is often combined with the concept of prestige, where players can reset their progress in exchange for bonuses, allowing for faster progression in the next playthrough.

Idle games thrive on the sense of progression and reward, keeping players engaged by offering frequent upgrades and unlocks. Popular mobile idle games like Idle Miner Tycoon and Adventure Capitalist utilize this Auto Play feature, where players can let the game run in the background. The appeal of idle games lies in their low effort-to-reward ratio, making them accessible to casual players while still offering depth for those who want to optimize their progress. This genre continues to grow, with developers introducing new mechanics and hybrid models, combining idle elements with genres like RPGs and strategy games.
