About ujem
ujem is a free mobile-first mini-game portal. Open the site in your phone browser, tap a game, and play instantly — no install, no sign-up, no email required.
The games
We currently host 50 short, snackable games covering puzzles, reflex, memory, arcade, and classics. Each game runs entirely in your browser and works offline once loaded, so you can play on the subway or anywhere with spotty connection.
Mobile first
Every game is designed for one-handed portrait phone play. Tap targets are large, layouts are vertical, and load times are kept short. There is no app to install.
Languages
ujem currently supports English, 한국어, 日本語, Español, Português, and 中文 (Simplified). The language follows your browser preference and you can change it at any time from the selector at the top right.
Anonymous by design
You can play without creating an account. Hall-of-Fame entries use only a nickname and a country flag you choose; we never ask for your real name or email. See the Privacy Policy for details.
