Whamageddon Rules: How to Play, What Counts, and How to Survive Until Christmas Eve

The short answer: the rules

Whamageddon is a survival game. You try to get from December 1 to the end of December 24 without hearing the original Wham! recording of "Last Christmas". The official rules at whamageddon.com fit in four lines:

1. Stay alive from December 1 through December 24.
2. Only the original Wham! recording counts. Covers, remixes and versions by other artists are safe.
3. The moment you recognise the song, you're out.
4. If you're out, say so on social media with #whamageddon.

There's one bonus rule: playing the song on purpose to knock out your friends is, in the site's words, "thoroughly un-Whamly". It's frowned on, not banned.

People who lose go to "Whamhalla" and stay there until the next year's game (Wikipedia: Whamageddon). That's the whole game. The hard part is that "Last Christmas" is everywhere in December. Last year it climbed to No. 2 on the Billboard Hot 100 (chart dated December 13, 2025), its highest US position ever, and it was the most-played song on North American adult contemporary stations that went all-Christmas in 2023 (Wikipedia: Last Christmas; Wikipedia: Whamageddon).

This guide is for the person whose group chat just said "Whamageddon starts December 1, who's in?" and who wants to know what actually counts before they agree.

What counts, and what doesn't

The official rule is short, so most arguments are about the edges. Here's how the rules read, and where your group should decide for itself.

Settle the grey areas in the group chat on November 30, not on December 12 when someone is trying to argue their way out of Whamhalla. The three that cause fights: remixes, the Pudding Mix, and whether hearing it deliberately played at you still counts. (By the official rules it does. Recognising it is all that matters.)

When does it end? At the end of December 24, so midnight going into Christmas Day, in your own time zone. On December 25, play it as loud as you like.

How to start a game with your group

Most groups run it on the honor system in one group chat. Here's a setup that takes five minutes:

1. Send the four rules to the chat on or before November 30, with your house decisions on remixes and the Pudding Mix.
2. Agree on how to report a loss. A message to the group is enough. Posting with #whamageddon is the official way, and it's half the fun.
3. Keep a list. Pin a message with everyone's name and edit it as people fall. Note the date and where they were. "Dec 3, Target, aisle 7" is how these stories get told for years.
4. Decide what the last one standing gets. Bragging rights are traditional. A group that does a gift exchange can let the winner pick first.

Two variations people play:

• Wham!Hunter. Instead of being knocked out, you score a point every time you hear the song. Highest score on December 24 wins (Wikipedia: Whamageddon).
• Early start. Some people start on November 1, when Christmas radio formats traditionally begin. That's not the official version, so say which one you're playing.

At work, keep it opt-in. Someone who didn't sign up hasn't lost anything when the song plays in the break room, and the person who plays it on the office speaker "by accident" will not be forgiven.

Where you're most likely to lose

Nobody survives Whamageddon by luck. These are the places that knock most people out, and what to do about each:

• Shops and malls. In-store playlists in December are heavy on the same few songs. Wear headphones with noise cancellation on and your own music playing while you shop. It's the single best defense.
• The car radio. Stations that go all-Christmas play "Last Christmas" constantly. Play your own music in the car through December, and ask rideshare drivers whether you can choose the music or turn it down.
• Gyms, coffee shops and restaurants. Same problem as shops, less control. Headphones again, or a quick exit when you hear a sleigh bell and a synth.
• Office and holiday parties. Ask whoever is doing the music to leave it off, or ask for a cover version instead. A party host who knows the game is on will usually play along.
• TV, streaming and social media. Holiday ads, specials and short videos use the song. Scroll with the sound off in December, and mute the ad breaks.
• Your own phone. Music apps fill gaps with whatever is popular, and in December that means "Last Christmas". Radio stations, autoplay, "similar songs", AI DJs and the charts are all risks. The next section shows how to lock down the one place you control.

Know the intro. The original opens with a drum machine and a bright synth line before George Michael starts singing. If something in a shop starts to sound like it, leave or put your headphones on right away. Waiting to be sure is how people lose.

A Christmas playlist that's safe to put on

You don't have to give up Christmas music for three weeks. You just have to choose it yourself. These are big, well-known Christmas songs, none of which is "Last Christmas":

• "All I Want for Christmas Is You", Mariah Carey
• "Rockin' Around the Christmas Tree", Brenda Lee
• "Jingle Bell Rock", Bobby Helms
• "It's the Most Wonderful Time of the Year", Andy Williams
• "Feliz Navidad", José Feliciano
• "Santa Tell Me", Ariana Grande
• "Underneath the Tree", Kelly Clarkson
• "Step Into Christmas", Elton John
• "Fairytale of New York", the Pogues featuring Kirsty MacColl
• "Wonderful Christmastime", Paul McCartney
• "Christmas (Baby Please Come Home)", Darlene Love
• "Run Rudolph Run", Chuck Berry

And yes, you can still hear "Last Christmas". Covers are safe, so a covers-only list keeps the song in your December without the risk:

• Taylor Swift (on The Taylor Swift Holiday Collection, 2007)
• Carly Rae Jepsen (2015)
• Ariana Grande (on Christmas Kisses, 2013)
• Hilary Duff (on Santa Claus Lane, 2002)
• Backstreet Boys (on A Very Backstreet Christmas, 2022)
• Jimmy Eat World

Years and albums are from Wikipedia's "Last Christmas" article. Check the artist name on screen before you press play: a search for the title alone will usually show the Wham! original too.

If you'd rather take a break from Christmas songs altogether, winter songs that aren't Christmas songs has a whole season of music without a single sleigh bell. For a bigger list of Christmas music, see the best Christmas songs.

Playing it safe in Trending Music

Trending Music is our app, so weigh this section accordingly. It's free, and it can play everything in the lists above. Here's how to set it up so your own phone isn't what knocks you out:

1. Build a playlist and play only that. Search for each song, tap ••• on its row (or press and hold it), choose Add to Playlist, then New Playlist, and name it "Wham-free". Add the rest the same way (playlist guide).
2. Search covers by artist, not by title. Type "Last Christmas Carly Rae Jepsen", not "Last Christmas". Check the artist name on the row before you tap it.
3. Turn off Autoplay in the app's Settings > Playback. It's on by default, and it keeps similar music playing when your playlist ends. In December, "similar music" to a Christmas playlist is exactly where the original turns up.
4. Skip the Christmas radio stations and the AI DJ until December 25. Both choose songs for you. The AI DJ has a thumbs-down that stops it playing a song again, but you only get to press it once you've already heard the song.
5. Steer clear of the charts. The original climbs the charts every December, so top-songs lists are risky until the 25th.

What it can't do: there's no way to block one song or artist across the whole app. The safe approach is to play only music you picked yourself.

About ads, honestly. The free version shows ads, including full-screen ones while the app is open on screen. Premium removes them.

Where Whamageddon came from

The game's roots are online forums. One of the earliest known references is on a German games-magazine forum in November 2009, and in 2010 the sim-racing forum GTPlanet ran a near-identical challenge that ended on December 31 instead of Christmas Eve (Wikipedia: Whamageddon). It's modeled on an older dare, the Little Drummer Boy Challenge, which works the same way with a different song.

Four friends from Denmark also say they came up with it. In December 2023, one of them, Thomas Mertz, told CBS News the idea dated back roughly 18 years, because "this song was being played constantly, over and over" (CBS News). The forum posts and the friends' story don't quite line up, and nobody has settled it. What's clear is that by the mid-2010s it had a name, a website and a hashtag.

The song itself is older than the game by 25 years. George Michael wrote and produced "Last Christmas", and Wham! released it in December 1984. It reached No. 2 in the UK that Christmas, held off the top by Band Aid's "Do They Know It's Christmas?", and finally got to No. 1 there on January 1, 2021, 36 years later (Wikipedia: Last Christmas).

Does it count if someone plays it at me on purpose?

Yes. The official rules say you're out the moment you recognise the song, and they only call deliberate playing "unsportsmanlike", not forbidden. In 2023, a DJ at a football stadium in Northampton, England, played it to a crowd of more than 7,000 and later apologised (Wikipedia: Whamageddon). If your group wants a "sabotage doesn't count" rule, agree on it before December 1.

I already lost. Now what?

Welcome to Whamhalla. Post your #whamageddon, tell the group where it got you, and enjoy the song for the rest of December, though maybe not with your friends in earshot. Then start planning for next year: headphones, your own playlist, and Autoplay off.

More for December

If you're also running music at a gift exchange this year, music for a white elephant gift exchange has a passing-game song list (leave "Last Christmas" off if half the room is playing). For a sing-along that doesn't need a speaker, Christmas caroling songs everyone knows has the words most people half-know. And if you want a station that's playing Christmas music right now, Christmas radio stations covers when they switch, just not during Whamageddon.
