From the back of the box: Luck as well as strategy are important in this game. It starts out with the board filled with 36 coloured marbles in random distribution. Move by move players pick up marbles, trying to collect colours. Colour sets score higher! 1. Each players has an arrow at the edge of the board, which he moves. 2. The players take the marble which is at the intersection of the two arrows. 3. This is the table of points: the higher the number of marbles in one colour, the higher the score! 4. The board is easily prepared for each new round. Intersection, the original version, was played with 25 discs on a 5x5 grid.
