Twelve
There are sixteen pieces: three each of numbers one to five, plus an extra three. The pieces are randomly divided between the two players. The board is a 4 x 4 grid.
The players take turns placing their pieces on the board. When an orthogonal row equalling twelve is formed, the player gets a point. The player who gets the most points wins.
The pieces can be made from wood disks and the board can be made from sixteen pennies.
It's a good game that gets to be a brain burner halfway in as players must forecast
possible moves.
There is one problem with the game: the last player to play has an advantage.
