Play Relentless Logic Online

Relentless Logic is that rare MS-DOS puzzle game where you’ll stare at the screen for five minutes, convinced there’s no solution—then suddenly smack your forehead when it clicks. It’s all about sliding blocks and outmaneuvering the game’s cruel but clever rules, like some unholy hybrid of chess and a Rubik’s cube.

The first few puzzles trick you into thinking it’s easy. Then the difficulty spikes hard, and suddenly you’re scribbling notes on scrap paper. The graphics are barebones (we’re talking monochrome lines here), but that just means nothing distracts from the sheer agony of your third failed attempt at level 12.

Honestly, half the fun is the frustration. When you finally crack a puzzle that’s been wrecking you for an hour, it feels like solving a murder mystery. Not for the impatient, but if you miss the days when games didn’t care about your feelings, this one’s a brutal little masterpiece.

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