The "taquin" game (or game of fifteen) is a classic puzzle game in the form of a wooden square containing a split and mixed picture. The goal of the game is simple: rearrange the tiles to rearrange the entire picture.

     The difficulty of the game lies in the number of tiles to be repositioned, but also in the structure of the image and whether any tiles contain fractions of the image that are very similar. The combination of these two points can greatly increase the resolution time!
