Battleships: Classis

Battleships: find the fleet by its numbers

The rules

  1. Hide the whole fleet shown under the board: each ship a straight line of cells, across or down.
  2. The number beside a row or column says how many of its cells are ship.
  3. Ships never touch each other, not even at a corner. A revealed cell shows water or the part of a ship it is.

How to play here

Tap a cell for ship, again for water, again to clear it. Cells left open count as water. Drag to mark several cells in one stroke.
