Run the game and enjoy.

From the original game's manual itself:

The goal of the game is, to put the 72 stones on the board. Each stone is
characterized by a combination of one out of six colors and one out of
six symbols. This gives 36 different stones, and there there are two of
every kind.
In the beginning there are six stones on the board, and at the top of the
right side, there is a stone shown, that you must place on the board. The
stone can only be placed on a field, on the following three conditions:

• The field must be adjacent to at least one stone.
• The stone must correspond with all adjacent stones in color and/or
  symbol.
• The number of neighbors of same colors, and the number of neigbors of
  same symbol must not differ more than 1.

The more neighbors a stone has, the higher is the score you get:

1 neighbor (1-Way) : 1 point
2 neighbors (2-Way) : 2 points
3 neighbors (3-Way) : 4 points
4 neighbors (4-Way) : 8 points

If you make a 4-way you'll get a bonus (25 points for the first 4-Way, 50
for the second, 100, 200, 400, 600, 800, 1000, 5000, 10000, 25000 and
finally 50000 (fifty thousand!)).
After each 4-Way the points for all following moves are doubled, i.e 2,4,8
and 16 points after the first 4-Way, 4,8,16,32 after the second, and so on.

Game can also be played by two players who play one after another, on the same computer/device. No internet game for now, maybe later. It will add some more spice if you haven't enough yet.
