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 style. A single game consists of short sets, either 30 seconds or 45 seconds in different versions. The game is won after winning two sets or sudden death after two draws.
Signature moves are added for a futuristic touch. Players can charge the meter for special moves by blocking, tossing, or lobbing the disc 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.
