===Text-based version===
Text-based game that works with both command-line and [http://miniscript.org/MiniMicro Mini Micro] versions of MiniScript. The Mini Micro has animation showing the changes in the board when the tiles are being shuffled or a move is made.

===Fully animated version===
This fully animated implementation is for use with [http://miniscript.org/MiniMicro Mini Micro]. It uses assets that come with the Mini Micro as well as a sound file of wood blocks scrapping and hitting each other that is separate from this code. This scrip will still run without it and will not simulate the sound of the tiles moving. You may find this file on [https://github.com/chinhouse/MiniScript/blob/main/Puzzle-15/small_wooden_bricks_movement.mp3 Github].
