Idle games that earn for you while you're doing something else. Open one in a browser tab, click a few times to get started, buy upgrades, and come back later to progress. No download, no account, no in-app purchases.
Idle games (also called incremental games or clicker games) are a genre where you accumulate a resource — capybaras, coffee, coins — by clicking and buying upgrades. The key mechanic is that the game continues progressing even when you're not actively playing. You open the tab, click a few times, buy an upgrade that automates production, and come back later to find you've earned thousands more.
The appeal is low-pressure progression. There's no way to lose, no reaction time needed, no skill ceiling. You're just watching a number go up, occasionally making decisions about which upgrade to buy next.
Most idle games on app stores require 100–500 MB downloads and include in-app purchases or ads. Capybara Clicker and Coffee Clicker load in under 3 seconds in any browser and are completely free — no purchases, no account required. They work on phone, tablet, and desktop.
