Simulation games you can play in your browser

99 games right now, and the number moves most days because new games launch daily. Everything counted here is published and playable, not a store page or a wishlist entry.

Hot weighs recommendations and reviews against how long a game has been up, so a strong launch from this morning can outrank an old favourite. New is strictly by launch time, Top is lifetime recommendations, and Discussed is review count. One account, one vote per game.

Going by the tags makers picked themselves, the most common right now are free to play, ai built, instant play and simulation. Each of those is its own page, so you can narrow down from here rather than scrolling.

It depends how the maker stored time. Most compute offline progress from a timestamp when you come back, which works fine. A few only tick while the tab is open, and those say so, because it changes how you play them.

Wildly variable. A physics toy is five minutes. A well-built idle economy can eat a fortnight. The tagline on each card is usually honest about which one you are looking at.

Almost always, through your browser storage. Clearing site data wipes it. If a game supports an export string or a cloud save, it will be in the description rather than hidden in a menu.
