Gigantosaurus Tic Tac Toe

Gigantosaurus Tic Tac Toe swaps the usual Xs and Os for a prehistoric board. In this dinosaur game, round stones mark one side while animal bones mark the other. The match plays out on a 3x3 grid with easy and hard settings. Build a line of three across a row, down a column, or on a diagonal before your rival does.

How to play?

Check the nine spaces before you click. Pick an open square and place your mark there. The stone side moves first. Watch the next open lane after every move. Block a row when your rival gets two matching marks. On hard mode, plan one move ahead and leave yourself two possible winning lines.
