A fierce battle awaits you in the seas of the game Sea Battle 505. You will take part in a naval battle with your armada of large and small ships. Place them on a small field of cells. Next, you will receive a nearby field of exactly the same size, with enemy ships hidden on it. It can be either a gaming bot or an online opponent of your choice. Click on any cell on the right side of the field and if a red cross appears, you have hit the enemy ship. The moves will be made in turn; whoever destroys all the opponent’s ships the fastest will win Sea Battle 505.
