This game has the same principle as BLOXORZ, Rolling Block mazes or Block. You have a field made of squares. There's block 1 square wide and 2 squares long. You can roll this block in 4 direction using the arrow keys. Logically, in some positions the block will occupy 2 squares and in some positions only one. Your goal is to reach the finish and put the block on the exit square with the 1 square face. There'll be different squares with different features. Try them to see what each one does.
