Brix

If Tetris and a Rubik’s Cube had a weird love child, it’d be Brix. This 1992 brain-snapper is a tile-sliding puzzle game where every move counts and logic is your only weapon. You'll feel brilliant one moment, and hopelessly trapped the next. The graphics are sleek, the puzzles are cruel, and the sense of accomplishment when you finally solve one is worth more than your GPA.
