Best Idle Games

What Are Idle Games?

Idle games (also known as incremental games or AFK games) are a genre where the game continues to progress and generate resources even when you're not actively playing. You set up systems, buy upgrades, and then let the game work for you — earning rewards while you sleep, work, or do anything else.

The genre gained massive popularity with games like Cookie Clicker and Adventure Capitalist, which showed that the simple act of watching numbers grow could be incredibly satisfying. Players start with a single resource generator and gradually build complex systems of automation, multipliers, and prestige mechanics.

Unlike clicker games that require constant active input, idle games are designed for busy people who want to make progress without constant attention. And while incremental games focus on strategic upgrade planning, idle games emphasize the satisfaction of passive growth and long-term accumulation.
