Rush Hour is a sliding block puzzle invented by Nob Yoshigahara in the late 1970s and first sold in the United States in 1996.
The goal of the game is to get a red car out of a six-by-six grid full of automobiles by moving the other vehicles out of its way.
The board is a 6x6 grid with grooves in the tiles to allow cars to slide. The game comes with 11 cars and 4 trucks, each colored differently. The cars take up 2 squares each; the trucks take up 3.
Each puzzle card shows how the game is set up. While it is shown exactly which cars/trucks of which colors go where, placing cars of different colors in different squares does not matter since they are equal in size. This still makes it difficult to solve the puzzle using the instructions on the back.
The cards are each numbered. Higher numbers represent more challenging puzzles.
Cars and trucks can only be moved within a straight line along the track. They cannot be rotated.
