50 Free Games Without WiFi | Play Offline Now

Most browser games need internet because they load from a server every time you visit. But there's a way to play browser games completely offline — and it works on iPhones, iPads, Android phones, and computers.

PlayBrain supports Progressive Web App (PWA) installation. After your first visit, the games are cached locally and load instantly even when you're offline — airplane mode, underground, wherever.
