Pocket Battleship Book for Travelers

I have been travelling for long from home to office with colleagues. So thought to make a battleship booklet game which can be put in the pocket and played on the go. I made for myself the A6 format battleship. This easy to carry in the pocket and requires least accesories to play (just a pencil)

Ingredients required:
Pencil/pen
Paper to print on
Staples

Here is attached 3 variations of the same battleships game.

A4 sheet: This gives a full sheet of battleship game. This has been designed so that it can be printed on both sides of a single paper. Just select the count when printing and select the double side option.

A5 sheet:This gives a booklet format of battleship game. This has been designed so that it can be printed on both sides of a single paper. Just select the count when printing and select the double side option. Fold the sheets in the middle and staple them. You got yourself a booklet to play battleship. Make 2 of them.

A6 sheet:This gives a pocket size format of battleship game. This has been designed so that it can be printed on both sides of a single paper. Just select the count when printing and select the double side option. Cut the papers in half before folding the sheets in the middle and staple them. You got yourself a pocket sizes format of battleship to play along while you travel. Make 2 of them.

Make a cardboard cover for the booklets to keep if from tearing and getting damaged.
