Idle and incremental game sites

Updated 14 November 2026 · 13 sites, each checked the same way

Idle games begin with a few clicks and slowly grow into something that runs by itself. They’re made for dipping in and out: check in, make a few decisions, and leave them to carry on.

Many are made by independent developers and play entirely in the browser.

How to choose

  • Check how the game saves. Most save in your browser, so clearing your browsing data can lose your progress.
  • Some idle games keep progressing while the tab is closed; others only while it's open.
  • Text-based idle games are often lighter and work well on older computers.

Questions

What is an idle game?
A game that starts with simple actions, like clicking, and gradually builds systems that run on their own, so progress continues while you do something else.
Will I lose my progress?
Most idle games save in your browser. Clearing cookies and site data, or switching device, usually starts you again unless the game offers an export or an account.
