Sometimes unsolvable This game simply generates random arrangements of the tiles, which at first seems like a great idea. But in all 3 sizes, this renders the puzzle mathematically unsolvable about half of the time. Also would be nice if the best times were separate for each size. It's stupid to be compared to my best 3x3 time when working on a 6x6 puzzle that can't possibly be solved that fast.
I wrote a computer program to check if a solution exists, and often times it doesn't. Not nice to make people solve puzzles with no solution...
Sometimes unsolvable Random arrangements of 15 are not always solvable
Bad math Lots of insoluble combinations.
