Player A faces a line of players. The first player in the line fires a word at Player A, who immediately responds back with any word. Then the next player in line fires a word. Again, Player A responds with any word. This process continues down the line, with Player A responding as quickly as possible. After reaching the end of the line, Player A takes the first position in line and the last player in line (Player B) steps out to face the firing line. Player A fires the first word and Player B responds. The process continues down the line. The pattern repeats until each player has faced the firing line.
