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. Points are scored by throwing a disc into the goals behind a player or whenever the opponent is not able to catch the disc in time. There are two moves: a regular throw and a lob. By using quarter-circle movement, players can also add effect to the throw. To catch difficult discs, they can slide to reach them faster.
The game features six characters to choose from, each with their own abilities and court layout suited to their skills. A single game consists of short sets of 30 seconds or 45 seconds in different versions. The game is won after winning two sets or sudden death after two draws.
For a futuristic touch, signature moves have been added. To charge the meter used for special moves, players must block, toss, or lob the disc and then charge while it's in the air. These moves can be countered and sometimes knock an opponent into the goal.
The game includes two mini-games between levels: playing fetch with a dog and Flying Disc Bowling.
