Like Skins, the winner of each hole earns a skin, but unlike a typical Skins game, skins are not carried to the next hole in the case of a tie. At any time during the hole, a player can Hammer (or press) the hole. If accepted, the hole is worth double, and if conceded, the player who hammered wins the skin regardless of the final scores. A player cannot hammer two times in a row on a given hole, but players can hammer back any number of times. Skins are accumulated throughout the round and wagers are made either per skin or to the player or team with the most skins at the end of the round.

Air Hammer is the most common variation of Hammer where you can only hammer the hole while your opposing players ball is in the air! This makes for some spirited hammer declarations!!
