So if you are looking to win some money, you are better off playing the lottery than playing at McDonalds. Odds of winning $5k in McDonalds monopoly game is 1 in 578 million. Odds of winning multi-state powerball jackpot. 1 in 175 million.
What I found interesting though was that to win the million in Mcdonalds game is that the odds are 1 in 306 million. So it seems you have a better chance to win a million in their game than win $5k.
