Reason for invalid move in tic-tac-toe not clear to user

[yuki-zmstr]

Here I try to place my O at an occupied box. The user could appreciate some guidance why the move is invalid, perhaps like a one-liner "there is already a mark there!"

Team's Response

Thank you for your suggestions! The board will displayed each time player and AI place the mark successfully. Player would notice the cell is occupied when prompted "move is invalid". This would make the UI clean and improve user experience. Adding another prompt like "there is already a mark there!" would make the interface more complex.
