This is the well-known tic tac toe game, ordered by my son for wasting some of our free time… There is no other hardware nor soldering for external components. Only the well known DUE platform, a 4,3" touch TFT display and its adapter. The code is based on UTFT library. You can download it from its original blog place. or from my drive below. There is also here the UTouch library for the touch screen. This is the original name but it is discontinued. The new version, URTouch library is located at the last link below.
