Play Klass of 99 Online
Dodge grumpy teachers, pull off dumb pranks, and sneak through pixelated hallways—it’s like Skool Daze got a fresh coat of paint with new classrooms, students, and that same chaotic charm.

Klass of '99 came out in 1999 as part of the MS-DOS Classic Games collection, developed by 3D Realms. It was a time when many games still relied on pixel art and keyboard controls, fitting right into that era of straightforward, screen-by-screen adventures without a lot of hand-holding.
You control a student navigating a school, avoiding teachers, pulling pranks, and trying to complete objectives without getting caught. The main goal involves exploring the building room by room, interacting with other students and objects, and causing mischief while staying out of trouble. Signature mechanics include dodging authority figures, setting up gags, and managing your visibility to avoid detention. The pacing is quick, and the difficulty comes from timing your movements and anticipating patrol routes. It feels like a chaotic, lighthearted challenge where every successful prank brings a small rush of satisfaction.
Each game uses different controls, most DOS games use the keyboard arrows. Some will use the mouse , "Alt" ,"Enter" and "Space bar".
