This head to head game is additive!
 
Rules of the game:
 
A shot glass is placed in the center spot.
 
Two players at the same time try to get their ring on their hook. When they hook the ring they move the shot glass towards their opponent.
This goes back and forth until the shot glass is moved off the board.
The loser is the one who ends up with the shot glass.
The loser can be made to drink a shot.
 
This can also be a team event by dividing up players for each side and moving in line until one team is done and declared the winner!
What the losers have to do is up to you.
