SortIt for Phone & TV


SortIt and SortItPro is digital version of the classic combinatorial game 15-Puzzle, invented 1874 in USA.


Game is also called Gem Puzzle, Boss Puzzle, Game of Fifteen, Mystic Square, 16-puzzle.


The famous chess player Bobby Fischer “was an expert at solving the 15-Puzzle. He had been timed to be able to solve it within 25 seconds” [WikipediA].


Classic version of game was extended from size “4 x 4” to everything between “2 x 2” and:


·         “5 x 7” on iPhone 4,

·         “5 x 8” on iPhone 5, iPhone 5s, iPhone 5c,

·         “6 x 10” on iPhone 6,

·         “7 x 11” on iPhone 6 Plus,

·         “9 x 11” on iPad, iPad mini,

·         “12 x 15” on iPad Pro.


The goal of game is to sort the buttons from the upper left to lower right corner.

At the end of the game the bottom right corner should be empty and all buttons should be ordered in numerically: 1, 2, 3 ..., left to right, top to bottom.


Game result can be saved in score database.
