Threes!

From Wikipedia:

Threes (stylized as Threes!) is a puzzle video game by Sirvo, an independent development team consisting of game designer Asher Vollmer, illustrator Greg Wohlwend, and composer Jimmy Hinson. The game was released on February 6, 2014, for iOS devices and later ported to Android, Xbox One, Windows Phone, and Windows. In Threes, the player slides numbered tiles on a grid to combine addends and multiples of three. The game ends when there are no moves left on the grid and the tiles are counted for a final score.
