Ultimate Tic Tac Toe

A larger grid changes the usual tic-tac-toe routine in Ultimate Tic Tac Toe. The board goes beyond the classic 3x3 layout, and four matching marks in a line decide the round. A second player fits right in for matches with friends or parents. Solo rounds bring in a computer opponent that rarely slips.

How to play?

Place Xs or Os on the expanded board and build a row of four before the rival does. Choose one of three computer difficulty settings for solo play. The easy setting offers the best shot at a win. Medium pushes back much harder. Hard mode gives the computer its toughest play, making each move on the grid more demanding.
