Today I finally beat Red Stone, the craziest puzzle to be found on the Android Marketplace. I'm pretty sure it's one of my greatest achievements. The idea is to get a red block out of a small bottle, where there's very little room for sliding blocks around, and the shapes bedevil your efforts. It's a truly brilliant puzzle, and it surely dates back decades, if not much longer.

Somebody recorded himself finishing it from scratch on YouTube. There are even a couple of videos on YouTube just showing the Congratulations screen at the end to prove they won.

The achievement is especially valuable because I realized that I'd seen this puzzle before. Sure enough - I had but upside down. Right when I downloaded Red Stone it made me flash back to Lufia 2 (an SNES RPG with A-class puzzles), and I was pretty sure I'd seen it before. I could never beat it back then, and it riled me...but now, my 13-year old self has been avenged.
