For anyone who has eagerly peeled back a McDonald’s Monopoly sticker in the hope of landing a life-changing prize, the code M721 might ring a bell.
It’s one of the most talked-about pieces in the popular McDonald’s Monopoly game in the UK, and for good reason. But what exactly is M721, and why is it such a big deal during the annual promotion?
Let’s explore everything you need to know about M721 McDonald’s, from what the code represents to how it could lead to a £100,000 prize.
What Exactly Does the M721 Code Represent in McDonald’s Monopoly?
The code M721 is not just a random combination of letters and numbers, it represents one of the most sought-after Monopoly game pieces in McDonald’s UK’s promotional campaign. Specifically, M721 is the code for the Mayfair property, which is part of the Dark Blue set in the Monopoly board.
Is M721 a Rare Piece or a Common One?
Yes, M721 is considered a rare piece in the game. McDonald’s Monopoly typically includes sets of properties where only one of the set is rare, making the rest fairly common to collect. For the Dark Blue set, M721 (Mayfair) is the rare one, while M720 (Park Lane) is the more commonly found companion.
What Property Does M721 Correspond To?
- M721 = Mayfair
- M720 = Park Lane
Together, they complete the Dark Blue set, unlocking the biggest cash prize on offer.
How Does M721 Fit Into the Monopoly Game at McDonald’s?
The McDonald’s Monopoly game is based on the traditional Monopoly board game but turned into a promotional competition. Customers receive game pieces attached to packaging (like fries, drinks, or burgers), and each piece represents a property from the Monopoly board.
The M721 piece (Mayfair) must be paired with M720 (Park Lane) to complete the Dark Blue set. Once both are collected, the player becomes eligible for one of the biggest prizes.
Only a limited number of Mayfair M721 pieces are printed or distributed, making it incredibly rare. Without M721, a complete Dark Blue set is impossible to achieve, no matter how many Park Lane pieces are collected.
