Worked for me. I collected all 24 items, got a popup at around item 21 telling me that I would receive 500 miles and got an email immediately after I finished the game.
Your 500 AAdvantageŽ miles will be posted to your account within 7–10 business days. Once miles have been deposited, they can be viewed here.
You can redeem your bonus miles for flights to almost 950 destinations worldwide on American Airlines, American EagleŽ or the American ConnectionŽ carrier, oneworldŽ member airlines and other AAdvantage participant airlines. You can also redeem miles for flight upgrades, vacation packages, car rentals, hotel stays and other retail products. Visit aa.com/redeem for all the different redemption possibilities.
Thank you, and we look forward to seeing you onboard soon.
