Chapter 45: Boats
You are given a grid and a fleet that must be placed inside it. Boats may be rotated, but no two boats may touch horizontally, vertically, or diagonally.
Numbers outside the grid tell you how many cells in each row or column are occupied by boat segments. Some boat pieces may already be given, including their orientation. A fleet list at the bottom shows every boat that still needs to be found.
Boats is the unreleased collection’s take on the well-known Battleships puzzle family.
