A 3 dimensional 4-in-a-row game. Players use cubes or cylindrical game pieces to be the first to get 4 in a row up, accross or diagonally on any level in any direction. That's it. The game board is a 4 x4 grid. On your turn, place your gamepiece on any space of the grid or stack it on top of any piece that has already been played. It starts out simple but quickly creates many opportunities to win... or lose. On the flip side of the board, play alternate versions. "The Wall" is a straight version that plays just like Connect Four. "Stonehenge" is a circular version. All have the same rule of 4 in a row in any direction. —description from the designer
