When playing 3D tic-tac-toe
it is possible for the person going first to always win
, simply by choosing the centre square as their first move. This is a radical departure
from traditional two dimensional tic-tac-toe
, where the game can always be brought to a draw but can never be won.
This can be easily proved with a simple mathematical proof - something that is very easy to show with pen and paper
but rather more difficult to do with ASCII art
