Play Connex Online

Connex is a puzzle game from the MS-DOS Classic Games collection, though its original developer and publisher details are not widely documented. It belongs to that era of straightforward, single-focus games designed to run on modest hardware, where the challenge came from mechanics, not graphics.

You control a cursor to select and swap nodes in a grid, rearranging tangled lines of different colors until each one connects cleanly from its start to its end point without crossing others. The main objective is to untangle every connection on the screen, which requires careful planning as puzzles grow more complex with added colors and restricted moves. Pacing is deliberate, almost meditative at first, but the difficulty ramps up steadily, demanding real spatial reasoning. It feels satisfying to finally straighten out a stubborn knot after staring at it for what seems like ages.

Each game uses different controls, most DOS games use the keyboard arrows. Some will use the mouse , "Alt" ,"Enter" and "Space bar".
