🎮 Welcome to Only Sz Games — Play Without Limits

What are Unblocked Games?

Unblocked Games are the online browser-based games that are not blocked on restricted networks, such as schools, offices, or public Wi-Fi, where gaming sites are often blocked. They run directly in your web browser, usually using HTML5 technology, so you don’t need to download or install anything. Because they’re hosted on open, secure servers, unblocked games can bypass filters that normally prevent access to entertainment or gaming sites.

At OnlySZgames, we specialize in providing a safe, high-speed library of games that are not blocked and work perfectly on Chromebooks, PCs, and mobile devices.
