4. Threes!
Platforms: iOS and Android
Price: $2
Sudoku has paved the way for true mental challenges. This game is no different. Threes! is played on a 4×4 grid with the player sliding tiles around, to make addends and multiplications to the number three without letting the grid fill up entirely. With each game lasting only about seven minutes or so, the player is rushed to try and create more multiples and addends faster and faster until no more moves can be made. You’re then given a total score that can be posted online to have other people challenge it, as the points are distributed based on the rarity of the tiles (differing colors such as red and blue) rather than having larger number tiles. It’s addictive and colorful as well as educational to a certain degree, serving as an awesome option for parents and children alike.
