(iirc... it can be done in 3 moves)
If you like coin-moving puzzles, you may also like puzzles I called "tile-moving puzzles". I created a Java applet to construct and solve
them around 25 years ago (about the same time as my "coin-moving"
applet). The puzzles are like coin-moving puzzles, except square tiles
are used (e.g., Scrabble tiles). Java applets no longer work in most
browsers, but the instructions contain one example. The applet and instructions appear on my website at:
file:///C:/Users/cginnow/Documents/Websites/Microprizes/public/tilemove.htm
The goal of the tile-moving puzzles is to change one pattern into
another by moving the square tiles around on a grid. When a tile is
moved, at least two of its edges must touch the edges of other tiles.
The example puzzle on my website is contained on a 4x4 grid and involves transforming the pattern:
|X| | | |
| |X|X| |
| |X|X| |
| | | |X|
into:
| | | |X|
| |X|X| |
| |X|X| |
|X| | | |
(The diagrams are best viewed using a fixed-width font)
Solutions can be posted by giving the before and after coordinates (row, column) for each tile move.
