Explain xkcd: It's 'cause you're dumb.
2048 is a popular browser-based game in which players must move tiles in a 4 by 4 grid with numbers on them. When two tiles of the same number touch they can be merged into one tile with a value of the two tiles combined. So when two 4-tiles touch and are merged they form one 8-tile. The player can move the tiles by pressing an arrow key (or swiping in a direction on the mobile version), which will move all the tiles in that direction. Every time the player makes such a move another tile will appear on a random cell. The goal of the game is to get a tile with the number 2048.
In the comic the room number can be seen as 4 tiles with the values 8, 2, 2 and 4. If these occur in the game the player can merge the two 2-tiles into one 4-tile. This will then cause two 4-tiles to lie next to each other, so these can be merged into one 8-tile. Finally, the two 8-tiles can be merged into one 16-tile.
This can be done in the opposite direction as well.
The title text refers to Tetris effect, which takes its name from the game Tetris. People who play Tetris for extended periods tend to imagine real-life objects (like skylines) as tetris landscapes and pieces. Randall, as many others, apparently got hooked on Tetris so much when it came out that, for 20 years, he would look at city skylines and see Tetris-like patterns in it. Similarly, he has now been hooked onto 2048 and notices number patterns that would be desirable to obtain during the game.
Comics 724: Hell and 888: Heaven also refer to Tetris.

- Guy: The talk is in room 8224.
- Cueball: Ooh, nice.
- Guy: What?
- Cueball: ...Sorry. Nothing.
- Great, now I'll spend the rest of my life noticing numbers that would make good 2048 combos.

If you want a multiplayer version of the game, go to 2048.mx. (No one ever shows up and it's lonely here.)

Interestingly, the comic number is 1344, and the 2 4-tiles can be combined to give an 8-tile 184.108.40.206 (talk) (please sign your comments with ~~~~)
The title text... I guess that's just seeing how regular Tetris would play out on a cityscape? And not a special version of Tetris that used building looking pieces (I guess regular Tetris doesn't look very city-ish to me)

- I thought it was about looking at real life objects and mentally fitting them together. Then I visited the Wikipedia link provided here and I was right! I won't change the explanation because I'm the first one to expose this in the comments. 18.104.22.168 02:55, 4 March 2015 (UTC)
8224 is also (16*16*32)+32 and was a common number to see as a programming error on PDP11's in the 1980's when a (16 bit) integer of zero was stored as two spaces (ascii=32) rather than two nulls (ascii=0) 22.214.171.124 (talk) (please sign your comments with ~~~~)
Dammit, thanks to this comic, I found out this game exists. Now I can't stop playing it! Thanks a lot, Randall! 126.96.36.199 12:08, 21 March 2014 (UTC)
Whatever that site http://gabrielecirulli.github.io/2048/ is supposed to do, it doesn't do it on my Linux/Firefox setup. The multiplayer one at http://2048.mx/ does, thank you. PS the plurals of PDP11 and 1980 are PDP11s and 1980s. 188.8.131.52 10:48, 22 March 2014 (UTC)
- Shouldn't the plural of PDP-11 be PDPs-11? 184.108.40.206 17:58, 24 March 2014 (UTC)
- No...that's not a word any more than "Xboxs 360" or "PlayStations 4". The "-11" bit is part of the name. NealCruco (talk) 21:28, 25 April 2014 (UTC)
Yeah, the game only seems to run on Chrome, in my experience. Another interesting link: http://ov3y.github.io/2048-AI/ --Rakiru (talk) 15:45, 22 March 2014 (UTC)
2048 is so close to the weird Hong Kong film about a hotel room two integers lower and the digits evoke the end of freedom in HK (though the preview is so surreal that I can't tell if there is any future in the film or not) But the handover happened in '97 didn't it? This is kindof like naming a movie with 9/11 implications "August 2001" 220.127.116.11 03:05, 25 March 2014 (UTC)
I started seeing 2048 games whenever I closed my eyes. That was scary... 18.104.22.168 18:31, 26 March 2014 (UTC)
