Noughts and crosses has been around for many years and is a very simple game to play just by each player using pen and paper. The rules are very basic and easy to learn but there are strategies that can be used and these often come along with experience of playing the game repeatedly. This game is also commonly called tic tac toe in many countries but they are both the same game.
As stated above a piece of paper and a pen is all that is required, to start the game a grid is drawn that is usually 3 squares x 3 squares. You can make the game more complicated by using more squares but this does take more time to play and is not used very often.
The object of the game is to complete a full line of noughts or crosses either horizontally, vertically or diagonally. Players take it in turns to be noughts and crosses, the main reason for this is that the player using the crosses always takes the first turn which can be a large advantage, sharing the crosses gives each player the same amount of chances to win the game.
Once the player has drawn their cross in the grid the opposing player then draws their nought and the players then take turns alternately until the grid has been completed or one of the players has completed a full line on the grid with either noughts or crosses.
If all of the grid has been completed and no full lines have been completed then the game is classed as a draw. It is usual for the players to decide how many games are to be played beforehand and the overall winner is the player who wins the most number of games. If it is decided that nine games are to be played and one player reaches a total of 5 wins early in the game then that player is the winner and no other games need to be played, obviously this figure changes dependant on the number of games that are to be played.
