Windjammers is based on a real-life sport known as Saucer Tennis or Frisbee Tennis. Two players face off in an arena with a low net in the middle. The goal is to throw a disc into the goals behind a player, or catch the opponent's discs before they hit the ground.
The game features six playable characters, each with their own strengths and weaknesses. Games are divided into short sets, with the first player to win two sets or score in sudden death winning the match.
A unique feature of Windjammers is its use of special moves, which can be activated by charging a meter while throwing the disc. These moves can be countered and sometimes result in the opponent being knocked into the goal.
Between levels, players can enjoy two mini-games: playing fetch with a dog and participating in Flying Disc Bowling.
