This game is a sliding puzzle with variable table sizes.
There is always an unoccupied tile that can be moved by pressing the arrow keys on the keyboard. Tiles in the same row or column as the unoccupied tile can be moved by sliding them horizontally or vertically, respectively. The goal of the puzzle is to place the tiles in ascending numerical order. For more information check out: www.instructables.com/How-To-Solve-The-15-Puzzle
Player movements are simulated multiple times(based on the difficulty level) therefore there is no need to check if the table is solvable or not after the shuffling.
Tables bigger than 4 by 4 are printed as numbers rather than graphical objects.
Scores are calculated based on the table size, difficulty level, number of movements & the time taken.
