Tilt (1974)

Tilt is yet another marble race game. The object of the game is to be the first player to move all four of his marbles around the board and into the center "home" area. The twist is that the board see-saws up and down depending on the position of the marbles. At the start, the board is perfectly balanced, but as the players move the marbles, the board tilts back and forth depending on the weight distribution of the marbles.

There are 18 "slide" areas around the board, and should your marble end up in one of these slides, a tilt of the board may send your marble forward or backward, or possibly right into the "home" area." (Think "Chutes and Ladders" with actual chutes.)

Though essentially a children's roll-and-move game, young players will quickly learn how to make the laws of gravity work for them. There is also some low-level strategy as players may choose to move their marbles backward if it would allow them to enter a slide.
