The team scoring the most runs by the end of the game wins. The game consists of nine innings on a simplified baseball diamond.
Player 1 is always the visiting team and bats at the top of the innings, with Player 2 as the home team and batting at the bottom of the innings. The pitching player selects a pitch by pushing the controller in one of eight cardinal directions, each representing a different speed and direction. The batting player then attempts to hit the ball into play and reach base safely, so that subsequent batters can move to home plate and thus score a run. If the ball is hit into play, the pitching player uses the keypad to select the fielder catch the ball, then selects the player to receive the throw, to put the runner "out".
The batting player is able to advance the base-runners off base in an attempt to steal a base, but the pitching player can counter that with an attempt to pickoff the runners before the pitch is thrown.
If the score is tied at the end of the 9th inning, extra innings are played as necessary until a winner is determined.
