SOS Game

It is a traditional paper and pencil game. It is played by two people. Before game begins, one of the
three played mode should be selected (easy, moderate and brutal). Players take turns to add either
an “S” or an “O” to any square, with no requirement to use the same letter each turn. However, “S”
and “O” limitation exists on game. For each usage of them, decrease the limit. The object of the
game is for each player to attempt to create the straight sequence S-O-S among connected
squares (either diagonally, horizontally, or vertically), and to create as many such sequences as
they can. If a player succeeds in creating an SOS, that player immediately takes another turn,
and continues to do so until no SOS can be created on their turn. Otherwise turns alternate
between players after each move.
