No installs and no paywalls: Slide Blocks 3D is a puzzle game that starts the second you hit play. It is the kind of game where one clever move can untangle a board that looked hopeless. On mobile the game switches to touch controls, so your progress is never tied to a desk. And because it is hosted on LemonArcade, it stays unblocked on school networks and Chromebooks.
Work out the logic of each layout and solve it before you run out of options. On mobile, the on-screen touch controls take over — tap / drag — play. A couple of practice runs will teach you more than any instructions.
