Twelve starts off with sixteen dice, 1 1 1, 2 2 2,  3 3 3 3,  4 4 4, 5 5 5. These pieces are randomly divided between two players.

Players take turns putting one of their unused pieces on an empty position on the board. Each time a player makes a vertical or horizontal row of exactly twelve, the player scores a point.

3, 3, 4, 2 would get a point
5, 4, empty, 3 would get a point

Pennies are used to keep score. The player with the most points wins.
 
 

Previous version You can see the problems that were solved.

This is an empty frame. The construction is 90% done. The frame is fine . But now that the frame is done .. why not put a floor under it? A reason had been that the popsicle sticks will have gaps between them. Something to look into. It's nice to be able to move the board with pieces from one place to another.

Q: Is it just a coincidence that the dice fit in the holes perfectly?

A: Yes. These are dollar store dice, which I think are a little smaller.
