I had noticed that the computer A.I. is remarkably lucky in setting up chains, and I see that the internet rumors that the computer cheats are flying fast and furious. Which is why DS Fanboy's report that the cheating could be deactivated certainly raised my interest. It wasn't until I looked closely at the picture, and noticed the bit about the nude characters and secret cow level, that I remembered today was April 1st. And I should note, what I first took for DS Fanboy's April Fools prank actually originated with the game developers themselves.
Oh, and as for the cheating allegation, I think it just appears that way because the gems tend to clump together, and aren't particularly random.
UPDATE: I thought the odd method of entering the "cheat code" was to make it more difficult to tell it was a joke when the code didn't work, but it has been pointed out that the code is actually morse code for "I am a NOOB."
