This app is called OxO. You might call it Noughts and Crosses or even Tic Tac Toe but when I was growing up it was always OXO. I used to play it with my mother but this app lets you play against your tablet or phone or whatever device you are reading this on right now. You can also play against your mother or anybody else who happens to be near you right now.

It is April 2020 as I write this and I'm in Australia. We've all got lots of time on our hands so I used some of mine to write this app and now I'm going to spend some time playing it with my grandkids.
