This idea is presumably based upon the notion that there is an even distribution of the relevant monopoly "tokens" across a given market.

Think about that a little - in terms of the potential prize liability for MacDs.

The normal way of controlling such (to all intents) lotteries is to have a few "golden tickets" capable of winning the more interesting prizes that are only dropped into the market in very small numbers - sufficient only to match the pool of prizes.

My experience of such marketing schemes (now rather historic I will admit) is that many prizes remain unclaimed - but giving them away was not the purpose of the exercise anyway.

Still the exercise was a worthy one - and it should be fun watching everyone looking for exactly the same missing tokens.

Hi everyone! A fellow classmate and I have exams approaching, so we thought that the best way to procrastinate will be to build something. That's why we hacked Monopoly Exchange quickly (in about 2 days) to allow people to exchange stickers in the McDonald's Monopoly game and we are interested in your opinion!

You might get a spike in traffic when the game is on, so consider making one for the US version. But otherwise it will only be useful in the niche case where someone with a rare winning token got in on the last days and couldn't buy more to find the common matching tokens.
