In the late 19th century this puzzle drove the entire world crazy. When Sam Loyd introduced the game to the public in 1878 he used a trick to arouse interest for it - he offered a thousand dollars to the one who could solve it. The puzzle consisted of a little box with 15 numbered square pieces that could be slid around to be arranged in rows from 1 in the upper left corner to 15 last on the bottom row. But then only the last two tiles 14 and 15 were scrambled which made the puzzle mathematically unsolvable and made people rack their brains in vain.
This 15 Classic Slide Puzzle game is more humanistic. There is always a solution. The software implements a shuffling algorithm that performs scrambling by random moving, not by random placing. So you can enjoy the game having in mind that "there is always a light at the end of the tunnel".
Besides, you can use some simple effects for a change. The software offers the option of turning on simple sound effects and using different color schemes. You can choose colors for the play-field and tiles yourself or use predefined schemes. You can move tiles or you can use a right click of the mouse button to shift them. It makes the game fun to use even if it is quite simple.
Those who had the 15 slide puzzle in childhood will not fail to try the game in the digital format again. For the younger generation it will be an exciting discovery.
Some say that this game has a therapeutical effect and tile sliding calms down. Well, download and judge yourself.
The program is a freeware and runs on Windows platforms.
