Poly Plug Battleships

Submitted by:

Aim

To sink your opponent's battleships.

Number of Players
2

Equipment

1 Poly Plug set per player

Optional
A template marked A - E, 1 - 5 as axes, or one which can be read through the holes in a Poly Plug board and shows the co-ordinates of each hole.

Rules

  1. Remove all the plugs from the red board and store them in the bag.
  2. Place the red board behind a screen (eg: an exercise book standing up on the table) and place 5 yellow plugs anywhere in the frame as battleships.
  3. Take turns to guess the positions of your opponent's battleships by saying grid positions.
  4. If there is a hit, turn the plug over so it is blue side up, and tell your opponent.
  5. It is the caller's responsibility to find a way of using their remaining yellow/blue board and plugs to keep track of co-ordinates they have already called. Repeated co-ordinates waste a turn.
  6. First to 'sink' all the opponent's battleships is the winner.

Extensions

  1. If you call a hit you get another turn.
  2. Use 1 aircraft carrier (4 plugs horizontal or vertical), 2 battleships (2 plugs horizontal, vertical or diagonal) and 2 submarines (1 plug).
  3. Internet Battleships.
    Connect two players by email. They agree on a grid reference system and send the calls and results back and forth by email.
