Snakesaurus, Pongosaurus, and Minesweeptor appear the moment your internet actually drops, and clear out when it comes back. The moment your internet actually drops, 404 B.C. opens one tab with a small arcade in it. When the connection comes back the game freezes and closes itself — unless you'd rather keep playing. Install it once and forget it. No account, no setup, no settings you have to understand first. The next time the wifi dies, it's already there.
