Using the game is super easy. First, assemble the battleships by snapping the two pieces together. Then, place the battleships in the water, either in a pool or a kiddie pool if you're on land. Next, load your water blasters by dipping them in water and pulling back. Stand back and aim at your opponent's battleship, trying to sink it before they sink yours. Each time you sink a ship, you score a point, and the first to 5 points wins. As you play more, your aiming skills will improve, allowing you to shoot from farther away. When it comes to maintenance, after each use, dry the battleships and water blasters thoroughly to prevent rust. Store them in a cool, dry place. Be careful not to over - pull the water blasters as it may damage them. Also, when playing, make sure there's enough space around the pool or kiddie pool to avoid accidental falls or collisions.
