The rules are similar to the classic Battleship game rules:
1. Arrange your submarines on your 10×10 grid. You have 10 submarines at your disposal: one 4-cell long, two 3-cell long, three 2-cell long and four 1-cell long units.
2. Take turns with your opponent to fire at each other?s grid. If your attack hit an enemy?s submarine ? you can attack again. The turn goes to the enemy when you miss and vice-versa.
3. Nor you, nor your opponent can place submarines right next to each other. There needs to be at least one cell gap between each submarine. Remember this well so you can use this to your advantage!
4. Sink all of the enemy?s subs before he sinks yours. Use logic and strategy to predict where are his submarines located!
