A review of the 3M Bookshelf Game Jumpin (1964). Jumpin is an abstract strategy game for two players. The object of the game is for a player to move all of their "pawns" from one end of the board to the other. Pawns can only move by "jumping" over other pawns. A pawn can jump over one or more pawns as long as they are all in a row with no intervening spaces.
