A train track with the players' trains and balloons is shown. Both players point at a train with their cursors, reversing its direction. The game then starts.
The players have to tap their trains to reverse the direction they go so that they do not pop their colored balloons. Each player has three trains and five balloons to watch. If a train gets near a balloon, its siren will go off. A train will stop moving once it pops a balloon. A player cannot pop their opponent's balloons, as the player must pop their own first. Burst balloons will come back, and trains will start moving again a little after making contact. The first player to pop three of their balloons loses.
The winner does a victory pose while the loser sulks. The screen then cuts to the winner's train, which is traveling around the track.
