How to play
Find every ship hidden in the sea.
- 1
The fleet above the board is hidden in the grid. Ships lie straight, horizontally or vertically.
- 2
The numbers tell you how many ship segments are in each row and column.
- 3
Ships never touch each other, not even at the corners.
- 4
Some pieces are given. A rounded end means the ship continues the other way; a square piece is a middle part.
- 5
Tap a cell to cycle water → ship → empty. Drag to paint many cells. Tap a finished number to fill the rest of its line with water.
