Frequently Asked Questions
What are idle games?
Idle games (also called incremental or clicker games) are games where progress continues even when you're not actively playing. You start by clicking to earn resources, then invest in upgrades and automation so the game plays itself. Popular examples include Cookie Clicker, Pocket Farm, and Idle Clicker.
What are the best idle games for browser?
The best browser idle games on PlayBrain include Pocket Farm (farming sim with offline progress, avg 4+ hrs per session!), Cookie Clicker (the classic cookie empire), Idle Shape Factory (conveyor belt tycoon), Idle Realm (idle RPG), and Idle Clicker (pure incremental progression). All free, no downloads.
Do idle games work when the browser is closed?
It depends on the game. Some idle games save your progress locally and calculate offline earnings when you return. Others only progress while the tab is open. Either way, your progress is saved automatically so you can pick up where you left off.
