You slide a block left, clear a path, and that satisfying moment when the red piece finally shoots free — that's Unblock That in a nutshell. It's a sliding block puzzle game where you move pieces horizontally or vertically to create a clear lane for the target block to escape the grid. Every level starts simple enough, but the board fills up fast and suddenly you're three moves in, completely boxed out, rethinking everything. Can you find the clean exit before the puzzle ties your brain in knots?
How to Play & Controls
- Click and drag a block horizontally or vertically to slide it along its track
- Release to lock the block in place and assess your next move
- Move the red target block to the open edge of the grid to complete the level
- Undo a move by clicking theundo button if you slide something the wrong way
Tips & Tricks
- Scan the exit lane first and work backwards to identify which blocks are actually in your way.
- Horizontal blocks can only block horizontal paths, so trace vertical escape routes to find faster solutions.
- When you're totally stuck, count how many moves each blocking piece needs — the one requiring the fewest moves is usually your first play.
