About Justin Client

Justin Client runs entirely in your browser: click play and you're in, with nothing to install and nothing to sign up for. It keeps its rules small and its challenge honest, which is a rarer combination than it should be.

It asks for keyboard and mouse and a little patience, in that order. There's a fullscreen mode when you want the tab to disappear and the game to take over. It's the kind of game you open to test and close an hour later.

Hit Play above. No download will start — the game runs in the tab.

Tips for Justin Client

Play your first run as a scout: learn what kills you before trying to win.
