Popeye

Popeye is a free browser game you can start playing the moment the page loads — no download, no install, no account. It keeps its rules small and its challenge honest, which is a rarer combination than it should be.

It's played with keyboard and mouse, so there's no setup beyond your hands and the screen. Phone, tablet or desktop, it runs the same, so you can pick up where boredom finds you. Fullscreen mode is there when a browser tab starts feeling too small for the occasion. Give it three minutes. That's how these things start.
