Number Slide 15 Puzzle Instructions on Stage. When the Flag is clicked the puzzle is drawn in solved form, then "Scrambles" random moves are made (the Target moves to solve it). Like the physical puzzle multiple tiles may be slid in 1 move. The tile clicked & all tiles between it and the empty cell are moved. See "Number Slide 15 Puzzle 2" for a 2nd spiral solution and 2 challenges to convert it from one to the other.
Created by @gregatku for use in Coding Classes for Kids Unlimited, for whom I work as a Coding teacher. Uses numbered clones (each clone/tile has its own "for this sprite only" id variable, identifying which costume it wears) to represent the tiles. The main sprite (id=0) represents the empty cell.
