Triqui is the Android version of the classic game of Naught and Crosses. It is played by 2 players. Each player in turn puts their symbol, the 0 or the X, in the grid. The aim of the game is to get 3 X's or 3 0's in a row - vertically, horizontally or diagonally - whilst, at the same time, trying to stop your opponent from getting 3 in a row.
