Wildly popular iOS and Android puzzle game “Threes!” has made its way to Windows Phone today after making its Xbox debut late in 2014. Best of all? It’s free.
If you’re unfamiliar with Threes, the object of the game is pretty simple. Players are tasked with sliding tiles to combine matching numbers while trying to get the highest score you can before the board is full. If it sounds simple, that’s because it is—and that simplicity is what makes the game so attractive.
