Boomerang Sports Tênis is a game of doubles inspired by Wii Sports. It is the first title to exclusively use the Boomerang, Zeebo's accelerometer controller (different from the Zeebo Extreme series, which also supports the Z-Pad; however, the game was later re-released to support the Z-Pad). Players must swing the Boomerang like a racket to hit the ball while the characters move automatically around the court.
One or two players can choose doubles among 10 characters dressed in the most various ways (like a geisha, a cook, a nurse, a man in a cow costume, etc.). As the characters win matches, they grow on points which unlock new rackets (again in varied forms, such as a guitar, a rake, a pan, a broom, etc.). The game length and player's hand side can also be selected.
The game features also an online ranking on Zeebo-net in which players can compare their achievements. The ranking can be updated daily by players.
