How to play

Two private 10×10 seas with ships of 5, 4, 3, 3, and 2 squares, placed by the seed and hidden behind your own view.
Players alternate calling one square on the enemy sea; a repeat or an off-board call is rejected.
A hit does not grant another shot — the turn always passes.
A ship sinks when its final square is hit; sink all five to win, there is no draw.
