Tri-Trick is a puzzle made by Hidden One Design. It contains nine square tiles numbered 1 to 9, and one blank 1 by 3 rectangular tile. The puzzle has a horizontal slider that is 1 by 9, and a vertical plunger that is 2 by 3. They have a 1 by 3 area in common. Initially the horizontal slider has the tiles 1 to 9 in order. By moving the slider any three adjacent tiles can be brought into the plunger. The plunger is initially down, and contains the 1 by 3 rectangular tile. By moving the plunger up, any three adjacent number tiles can be swapped out for the rectangular piece.
