Unblock Slide
Slide the blocks out of the way to free the KEY block and drive it out of the exit. Daily and practice boards in three difficulties.
How to play
- Tap a block to select it. Horizontal blocks slide left and right, and vertical blocks slide up and down.
- Use the arrow buttons under the board or the arrow keys on your keyboard to slide the selected block one square at a time.
- Blocks cannot overlap or leave the board. Make room by moving the blocks that stand in the way of the KEY block.
- Slide the KEY block all the way to the right edge, at the exit arrow, to complete the puzzle.
Tips and strategy
- Start by looking at what blocks the KEY block directly, and work out where each of those blockers can go.
- A long vertical block that crosses the KEY row often needs the most space to clear, so plan it first.
- Moves are counted one square at a time, so try to reach the exit in as few slides as possible.
- Stuck? Reset restores the starting layout without changing the puzzle.
