Game Features
Moving several tiles at once
You can significantly reduce the number of moves by moving a tile that pushes others in turn.
Examples:- The tile "5" when moving down pushes the tiles "9-10", "7-11" and "12-16," meaning that four tiles are replaced in a single move.
- The tile "18" shifts the tile "13" if you move it to the right. Two tiles are replaced in one move.
Moving a square tile in two directions
Since there are two empty spaces in the box, sometimes you can move a square tile in two directions at once without lifting your finger from the tile.
Example:- "13" can first be moved to the left and then upward.
Tiles blocking each other
After certain moves, the tiles may happen to block each other. While you may seem stuck, there is always a solution.
The only unsolvable initial layout
When creating a new challenge, avoid the only unsolvable layout with the rectangular tiles blocking each other (see the screenshot).
This layout is only possible through rearranging the tiles and never occurs during gameplay.
Challenges
Set up the tiles and numbers according to the image. Then try and solve the puzzle as you slide the tiles to arrange the numbers in ascending order.
