Once you have clicked on start, it will ask you to be circle or cross. After this, just click one of the boxes to start. Some people might refer to this as Noughts and Crosses.
This project was quite arduous. I thought it would have been easier! Please add some ideas that I will try to add as this is the developing version. Update Log V1.0 - 08/11/2018 - This project was released. V1.0.1 - 08/11/2018 - Added a sensor for telling you to go or not. V1.1 - 06/01/2019 - First update in 2019, so welcome to the new year. Fixed some of the long running scripts in the computer to be slightly faster. V1.2 -23/06/2019 - Finally I got this done. Given the game a completely new design, as the other one took too long to load. Only 2 player mode currently available as the computer (1 player mode) is why it took so long. If nothing happens and the 3x3 grid is full, it means it is a draw and you have to start again.
