Описание

Magic Fifteen is a Slider Game where the numbers can be shifted around starting from a magic square, a normal slider, or an impossible slider. Magic squares are called magic because all rows, columns and diagonals add up to the same number. In Magic Fifteen, with the blank as zero, they all add up to 30. The squares are randomly retrieved from an internal data base containing 880 unique magic squares. The program also displays the Dudeney group number (1-12) and the magic square index number (1-880). The squares can be rotated and flipped to make 7040 different magic squares, but half of them are impossible to achieve in a standard Fifteen Puzzle Slider. The program allows 10 different transformations of the magic square and displays impossible if the transformation results in an impossible Fifteen Slider configuration. Rotation by 90 degrees or flipping left/right or up/down changes an impossible puzzle into a possible one.
