The first one to get five in a row wins. It's really a pretty straightforward game to play. Except for the fact that the game board is made up of rotating squares - one of which players turn 90° after each play they make. This, of course, changes the whole set-up of the game board - though players are still aiming to get five in a row. The travel game is made up of 4 squares (each with 9 depressions for the marbles), while the multiplayer version is made up of 9 of the same squares. Also, the playing pieces in the multiplayer version have a different color on each side, allowing 2 players to play one or two colors each; 3 players to play their own colors, or as a team against a single; and 4 players to play against each other or in teams of 2, utilizing each other's colors. A versatile game that takes a lot longer to master than it does to learn.
