Battleship Extreme online

How to play

1. Both players have five ships (5, 4, 3, 3 and 2) placed randomly on a 10×10 grid. Ships never touch side by side; corners may touch.
2. Question marks pop up at random on the grid you fire at, at most three at a time. Hitting one gives you a random weapon. You can carry up to three.
3. Instead of a normal shot you can use a weapon. Using a weapon always ends your turn.
4. A nuke hits a 3×3 square; a mini nuke hits a plus of five cells.
5. A scatter shot fires at your target plus five random cells.
6. A torpedo launches from the nearer edge of the row and runs until it hits a ship.
7. Radar destroys nothing but tells you how many unhit ship cells are in a 3×3 square. Your opponent sees where you sent it.
8. A normal hit gives you another shot until you miss or sink the ship. Sink the whole enemy fleet first to win.

Strategy

• Collect question marks early. A weapon in reserve is a threat for the rest of the game.
• Save the nuke for right after a hit. Around a damaged ship it lands far more hits than a blind shot.
• Send radar into large untouched areas. Even a zero tells you a lot: nine cells you can cross off.
• Fire a torpedo down a row you haven’t touched. It stops at the first ship, showing you exactly where it lies.
