A Chromebook is not a slow computer, it is a computer with no graphics card and often with four gigabytes of memory, sharing a school or office line with three hundred other people. Games fail on it for two reasons: they want an install it cannot do, or they want a GPU it does not have.
Everything on this page is an ordinary web page. There is no installer, no launcher, no plugin, no app store and no account — the address loads and the game is already running, which is also why it survives a managed network.
The second half is weight, and this is the part most games lists skip. Every game here was opened in a real browser and the bytes it actually pulls down were recorded rather than estimated. The median is 0.4 MB. Most are under a megabyte, and the heaviest thing in the whole catalogue is 7.7 MB — smaller than one photograph off a phone. They are that small because they share: nearly all of them are built on the same 3D engine served from one address, so the first game you open pays for it and every game after is a few hundred kilobytes of its own.
If a game does run badly on yours, close the other tabs first. Every open tab with a 3D scene in it is competing for the same integrated graphics, and on a Chromebook that is a real and immediate cost.
