Has a patent date of 1904, no manufacturing date information available. The game looks at first like a typical slider puzzle: take out the remove piece, then move the ball to the end zone. That is indeed the object, but there's two twists: 1) the ball cannot move backwards. Once you've moved the ball towards one goal or the other, you're committed to that direction, and 2) To complete the puzzle, the ball has to be in the end zone and all other pieces need to be in their original positions. Alternatively, makes a great display piece.
