ALL THE CODES ARE GONE! Congrats to all the winners! That's right, I've got 25 TanZen promo codes for anyone who wants one! This code is good for the current full version of TanZen, which has nearly 400 puzzles, so use it before the next version hits several days from now. Remember, promo codes only work for the U.S. App Store, so please don't ask for one if you can't use it. Anyone who wants one, please send me a private message, and I'll send you the code. First come, first served! Enjoy!
