Game Objective
Arrange the tiles into number order starting from the top-left corner. Unlike a normal sliding puzzle, you move a whole row or column at once, not a single tile.
Slide a row at a time to arrange the tiles into order.
How to Play
Click an arrow at the edge of the grid to slide that entire row or column in the arrow's direction. The tile pushed off one end wraps around and reappears at the other end.
These puzzles reward careful deduction more than speed. Start with the most constrained clues, eliminate impossible choices step by step, and avoid guessing unless the puzzle specifically calls for it.
Beginner Tips
- Think of each move as rotating a row or column by one step.
- First try to put nearby numbers into the right relative order, then move the group into place.
- Do not chase one tile with random moves; every move also changes the other tiles in that row or column.
