Threes! is an indie 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 and Xbox One by Hidden Variable Studios. 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.
Threes was conceived by game designer Asher Vollmer, who worked on the game with artist Greg Wohlwend and composer Jimmy Hinson. The three, as Sirvo LLC, had previously collaborated on the 2012 iOS word game Puzzlejuice. Wohlwend had worked on games including Ridiculous Fishing and Hundreds. Threes development began before Ridiculous Fishing '​s March 2013 release. Vollmer presented an idea similar to the final product in its simplicity: pair tiles as multiples of three. The first prototype was written in a single night. With Wohlwend, the two-man development team spent at least half a year of the game's 14-month development iterating on this main idea.
