Unblocking Wrench Puzzle

You've got a wrench stuck behind a wall of metal blocks. Slide them out of the way without getting jammed—every move counts.

This is a sliding block puzzle where you free a wrench trapped among metal beams. You click or tap a block and it slides in its allowed direction until something stops it. The wrench itself doesn't move; you clear a path for it to exit to the right. Simple idea, but the layouts get tricky fast. I kept underestimating the early levels—level 4 had me shuffling the same two blocks back and forth while the wrench sat there laughing. The satisfying part is when you finally spot the one sequence that lets everything fall into place. No timers, no penalties, just you and the puzzle. Perfect for a quick brain break between classes. Visuals are clean industrial: grey blocks, a red wrench, subtle shadows. Works on phone or desktop; tapping is just as precise as a mouse. If you get stuck, the reset button is your friend, but try to count your moves—some levels have a par you can beat. It's the kind of puzzle that feels obvious after you solve it, but stumps you for five minutes first.

Mouse click or tap to play

Work backwards from the wrench: figure out which block must move last to open the exit. Long blocks are often the real puzzle; move them only when you've cleared their slide path. Tap a block to see its allowed direction, even if you don't move it yet. Don't chase perfection early—just get the wrench out, then replay for fewer moves. If you're stuck, reset and try the opposite order of your last three moves.
