Love playing tic tac toe as a kid? Now you can love it as an adult with the 4Play 3D Tic Tac Toe Player. Unlike the traditional game, 4Play is a 4x4x4 tic-tac-toe board. Of course, the general goal is the same: get four in a row. It may sound complicated with four sides, but it’s actually easy to play; all you have to do is tap the buttons to have them light up. Although it may not be so easy to win. Combining the strategy of chess with the quick-thinking of Sudoku, 4Play is on a whole other level. Plus, there are also four different ways to play. You and a friend can play in person or you can use the app to play with friends from far away. Or, if you need a bit of competition, you can go against players all around the world through the 4Play app. If you’re looking for a real challenge, you can play against one of the seven 4Play algorithms, testing your abilities with each round.
