For two players. Here’s another popular game you can play without the official version. All you need is graph paper. Each player needs two grids. Label each grid by writing numbers across the top and letters down the side, so that the squares are easily identified as A8 or F5. One grid will be for locating your own ships, the other for recording shots against your opponent’s ships. Each player places three or four “ships” on his grid, then let the guessing begin. The first person to sink all the other person’s ships wins.
