Originally played using pen and paper, and now available as either a board game or in an electronic version, the battleship game originated from the early twentieth century, being the idea of Clifford Von Wickler, the game is ideally for two players, playing against each other. Although the battleship game can be adapted when played on paper the typical set up, and the one we refer to here, is where the game is played on one hundred squares in a grid of ten squares high by ten squares wide, where on the vertical axis the squares are labelled with a letter and on the horizontal axis, the squares are labelled by a number, this gives each square in the grid a unique reference, for example, A1, C7 or H8 and so on.
For each battleship game, both players need two of these grids. On one of the grids, to which we will refer to as the first grid, the players set out their battleships, which are identical in size for each player, this means that both player's grids have the same amount of squares occupied by part of a battleship and the same amount unoccupied. The sizes and class of each battleship can, and does vary dependant on the set of rules in use and battleships can only be placed straight, be that horizontally or vertically and never diagonal, neither are they able to overlap, where as parts of two battleships occupy the same square. The second grid for each player is to keep record of their own shots taken during the battleship game.
When the battleship game commences the player who is to play first, now named player one, announces a square they wish to fire at, let's say D4 for example, the players opponent, now named player two, at this point announces what damage, if any, that shot has done to any of his battleships.
Just as the above points to player one keeping their record of shots on their second grid, player two would keep exactly the same record on their first grid, the grid where they have placed their battleships and perhaps the same style of keeping record would be adopted, this is simply for player two to keep their own record of player one's actions. The battleship game then continues with the roles reversed, player two announces a square they wish to fire at, and the above is repeated in terms of keeping record. This sequence continues until one player has sunk all their opponent's battleships, thus winning the battleship game.
