Caps is a drinking game. It involves throwing bottle caps into 16oz-20oz beer mugs (North America, North Europe, and Argentina), or at another other bottle with a cap balanced on open beer bottles upside down. (France).
Four players split into two teams seated 8 to 16 feet apart(butts behind the cup), with a beer mug filled with beer placed between both players. Each side take turns throwing 1 cap each into their opponents' mug. Each time a team makes a shot, the other team gets a chance to "top it" or "match the shot" (rebuttal) by making a shot. If no cancel is made, the team that made the original shot or last top gets the points while the other team must drink a full beer between them. However, if a top is made, the team which originally made the shot tries to make a top as well. This exchange continues until a top shot is missed, at which point the team that missed drinks its beer and a point or points may be awarded to the team that made the last successful shot. The game then continues with both teams taking turns shooting.
The first team to reach five points wins, or the first team to be two points ahead after five. If there is an occasion where three out of the four players make a cap within four shots, the odd man out is the beer fetcher ("bitch"), and if all four players make back-to-back shots then a social is called and both teams drink their beers.
==Penn State Caps==
Penn State Caps is a version of the game played at Penn State University. The rules vary slightly.
The Penn State version of the game involves throwing bottle caps into pint glasses (16 oz.). Four players are split into two teams seated 6 feet apart on the floor with pint glasses between the players on each side. Knees must be behind the glasses. It is recommended to put cardboard under the glasses to prevent liquid spilling on the ground. Teams are seated diagonally, that is to say people from oposing teams sit next to each other. Each side takes turns throwing bottle caps at the opposite side's glass in a clockwise order, starting with the oldest person. Each time a cap is made, a point is recorded and the next person gets the chance to double the wager. If a double is made the next person gets the chance to triple, and if that is made the person after gets a chance to quadruple and so on and so forth. Whomever drinks is the next person to pour. After a point is scored, it is then the teammate of the last point's turn to shoot. If a player shoots out of turn, they must drink. Out of respect, their partner should, but does not have to drink with you. You are then skipped on your next turn. Complication: If a player makes a cap, and the next person is skipped, the next person in the order has a chance to double at the risk of the next player tripling and continuing play.
The first team to eleven points wins. However, you cannot win on a double, or triple, etc. You must win by two. If, at the end of the game, a player has not made a cap, they owe their partner a one page letter of apology.
Variations on this include line caps, and cross caps. Line caps is a variation in which three people sit on one side and the person in the middle is involved in two separate games at once. Cross caps is a variation in which two games are played in a cross pattern with eight people, perpendicular to each other. In cross caps, if caps hit in the air everyone drinks.
If at any point the game is tied and three of the four players call "dueces" the score is reset to 2-2 and any tie after that resets the score back to 2-2 again.
The game is considered a shutout at 7-0 and the losing team owes the person they are sitting next to a letter of apology.
