You will need a large playing area for this. Divide the area into two grids of 10 by 10 cells, label one side A-J and the other 0-9. The players are then divided into two equal teams. From each team two players are chosen. One of these players will be the hider the other will be the shooter. The shooters are blindfolded and have to wait while the hiders take the other players from their team and place them in the grid to form the various boats of a battleship game. The players should be lined up in lines of 2,2,3 and 4 finally the hider chooses somewhere to hide in the grid, they take up a single cell. The shooters must then remain blindfolded and call out firing co-ordintes such as B0 if there is a player in that grid cell, the player there calls out "hit", if the ship has been sunk they call out "sunk" Shooters take it in turns, even if they have just got a hit. The other players cannot help. Once all a teams boats have been sunk they are out and the game is over.
