Polar battleship Battleship, but in a polar grid. Instructions: Instead of a square grid like in the original Battleship, this version of Battleship uses a circular grid, with a point at the center and five circles around it. You'll be able to play against someone else locally. The instructions for the game are slightly modified from Battleship. Instead of placing the ship pieces in a line, you are allowed to make ships in various shapes as long as they are all connected. Click on the ship you want to place on the right and click on a hole to place it. Click on a ship to delete it. When both players have set up their ships, play begins. Click on a hole on the right, then press confirm to fire there. You will be told whether it was a hit, miss, or sink, and places you previously fired will be marked with a white or red pin. Your ships will turn red if they have been fired at by the opponent. Whoever sinks all of the others' ships first wins! Have fun! I took this game idea from my math teacher! ;)
