Unblock Blocks

Sliding blocks out of the way sounds simple enough — until you're three moves deep and realize you've trapped yourself completely. Unblock Blocks is a parking-grid puzzle where one stubborn green car needs a clear exit, and every other vehicle in the lot seems personally determined to stay in the way.

What makes it genuinely interesting is how quickly the board goes from readable to overwhelming. A layout that looks solvable at a glance might require a dozen deliberate shuffles in exactly the right order. There's a quiet satisfaction when the solution clicks — not because it was handed to you, but because you worked it out.

Horizontal vehicles only slide sideways. Vertical ones only go up or down. That constraint is everything. The whole puzzle lives in learning to think within those boundaries, planning four or five moves ahead while resisting the urge to just drag things randomly and hope for the best.
