Here's a Christmas game that you probably haven't played, but should, it's called "Whamageddon."
If you're thinking the game in some way involves the song "Last Christmas" you're absolutely correct.
The goal of the game is to go as deep into Christmas as possible without hearing the song, and if you want to know the other rules they've been circulating on Twitter pretty heavy lately.
The game lasts until midnight on Christmas Eve and if you make it to Christmas Day, you can put Wham! on repeat as much as you wish!
