I have made a fairly advanced variation off tic tac toe the rules are here:
• The board is made up of 9 square each containing one smaller tic tac toe board
• The objective is to line up three in a row on the big board
• To win a square on the large board you have to get three in a row in the square inside of it
• Once a square has been won it may not be played in
Advanced Rules(may be turned on or off)
• The large square in which you must play is controlled by your opponent’s previous move
• The large square that you must play in is the one which corresponds to the small square in which your opponent just played.
• For example, if your opponent plays in the top right square of a smaller board than your next move must be in small board in the top right square
I apologize if the instruction are a bit poorly worded but hopefully you can figure it out relatively quickly
