Chameleon Tic-Tac-Toe
Found this:
"It is well known that in classic Tic-Tac-Toe neither player has a guaranteed winning strategy.
However in Chameleon Tic-Tac-Toe each player may choose to place either a X or a O as their move,
and they may complete a row/column/diagonal of either three O's or three X's to win.
Which player, if any, has a winning strategy?"
Seems easy enough:
player who starts SURE to win if center spot picked;
if opponent picks a corner, then starter completes
diagonal, thus sure of winning;
if non-corner, starter completes row then column
(or column then row), thus sure of winning.
Ya'll agree?
