Network is a game using the physical sizes of the stones.

Number of players: 2-5
Time: about 10 minutes
Materials: 1 domino game with dominoes0-6.
All dominoes are shuffled upside down. They are divided among the players, any dominoes left are put aside and remain unused.
Every player inspects his own tiles. The player with the highest double puts it in the middle.
Players take turns adding a stone to the network. A stone may be added to any open end of the network provided that:
one of the numbers on the stone matches the number on the open end of the network,
to which the player adds the stone. (It is, adjacent numbers must match).
the stone does not match the edges of any other stones while the numbers are different.
corners with different numbers may touch.
a double may be added to at 4 sides: both ends and the middle of the two long edges.
A player may play or pass. The game ends when all players have announced a consecutive "pass".
Players earn 1 point for every ring formed in the network.
Count how often each number appears at an open end of the network.
The player contributing the last stone to the number appearing most often wins an extra 3 points.
The player with the largest number of points wins the game.
