How to play
- Place your fleet. Fit the five shaped ships on your 10 × 10 grid. Rotate them as needed, keep every cell on the board, and avoid overlap.
- Begin the battle. Fleet placement has a separate five-minute countdown. Missing fleets are placed automatically when it expires.
- Fire a cannon. Choose a cell on the enemy grid. A hit lets you fire again; a miss ends your turn.
- Build your supply. Gain 2 energy at the start of each battle turn and 1 energy each time any weapon hits a new cell of your fleet. Normal cannon shots are free.
- Choose a special. Plant a mine, attack a 2 × 2 area with a bomb, scan with radar, or launch a torpedo from an edge. You may reuse specials while you have enough energy, and your normal cannon shot stays available unless your bomb triggers a mine. The mine fires three return shots and ends your turn.
- Sink the fleet. Hit all 22 opposing ship cells to win. Score is separate from spendable energy.
