Cartesian Battleships
The Rules
You are the Admiral in charge of the following
ships:
3 Torpedo Boats – 1 Square in size, worth 1
point.
2 Cruisers – 3 Squares in size, worth 3 points
1 Aircraft Carrier – 5 Squares in size, worth 5
points.
You need to place these 6 ships vertically or
horizontally on the Cartesian grid below.
Each ship should be centred where the lines
cross.
In the example below, one of the
Cruisers sits on the points (2,4), (3,4) and (4,4)
Each ship must not overlap.
Do not show your partner.
Take it in turns to guess where you partner’s
ships are.
You must use the following method:
• Call out the position that you think your
partner’s ships are by saying the number
across the page first (x value), then down
the page second (y value).
• If you pick a square with some of your
partner’s ship on it, they must call out
“Hit”.
• If it is a whole ship (eg.
a torpedo boat), or
the last square that the ship is on they must
call out “Sunk” and you get t
