SortIt and SortItPro is digital version of the classic combinatorial game 15-Puzzle, invented 1874.
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” (http://en.wikipedia.org/wiki/15_puzzle).
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.

Ratings and Reviews
I tried several other 15 games, and I kept getting puzzles that are unable to be solved - the 15 and 14 are switched. This one has no real problems. Every puzzle has an actual solution. You can vary the size from 3 x 3 to 9 x 13. I got it to go up to 9 x 17 one time, but it won't let me go past 13 anymore. I don't know if this is a programming error or whatever, but that's really my only qualm with this. Great app that deserves all 5 stars.
With Family Sharing set up, up to six family members can use this app.
