Notes on Puzzle
A sliding blocks puzzle. The clue is all setup - the puzzle teller claims he once helped a UFO which had crashed by restarting their engine. You need to do restart the engine too, by moving the yellow energy ball from the left side to the right side. There are two 2x2 square blocks and 4 “L” shaped blocks along with your energy ball (also fills a 2x2 square). The shortest solution involves about 30 moves.
