tic-tac-toe tutorial is not fascinating

[yanjinbin]

i wonder it's popular in asia ?
i never heard of it,
so maybe this part maybe a bit boring for me
an small and easily understand game can be alternative to tic-tac-toe maybe attractive for me

@yanjinbin we are open to contributions, but tbh tic tac toe is small and easy to understand

I think it's originally from React docs.
