The player takes turns against the computer's AI in a race to destroy the opponent's Sats (or Satellites). Gameplay is very similar to the classic Battleship - There are three grids on the screen: The left grid shows your opponent's playfield and tells you if you've hit one of his Sats, or if you missed. The middle grid allows you to choose what area you will attack during your turn. The right grid displays your own Sats, their status, and the places where the opponent has already attacked. This continues until one side loses all their Sats.
The main difference between the Battleship board game and this Windows-based implementation is that there are five Sat pieces in play, all different sizes. While the board game has two pieces that are two blocks in size, this version contains one piece that's two blocks in size, and one piece that's one block in size.
