The game plays similar to Sega Superstar Tennis and does have similar minigames
Exhibition Mode offers the chance to challenge a character to a match on one of many courts, including Sam and Max's home court of the top of there office, or Jeera's Pupununu jungle court. Whichever court is chosen, there are a host of Telltale/similar animated celebrities cheering them on from court side.
Tournament Mode allows the player to play in a series of matches against opponents chosen at random by the computer in an arena also chosen at random.
There are several playable minigames in TelltaleTennis, including one such as a Pearlie meets Space Invaders game, in which the player has to hit moving targets in the form of dragonflyss, a Monkey Island game, a Puzzel Agent game, and a The Ricky Gervais Showgame.
Each character has their own unique 'special attack' giving the player more chance of scoring a point. For example: Gilius throws a magic bottle in the air and covers the opponent's side with thunderbolts, if they touch one the character will be stunned for a brief moment.
At the start of the game, players can play as Sam, Principal Pixiefrog, Hector, Potisha, Scout, Jeera, Max, and Huge Bliss. Other characters are unlocked by competing in tournaments.
