2048: Where It Came From, and the Corner Strategy That Beats It

2048 looks like a game of luck: you slide tiles around and hope the numbers line up. Plenty of people play it that way for weeks without ever seeing the 2048 tile. With one simple plan, keeping your biggest tile in a corner, making 2048 becomes something you can do most of the time. Here’s where the game came from, how it works, and the strategy step by step.

Where 2048 came from

2048 was made in March 2014 by Gabriele Cirulli, a 19-year-old web developer in Italy, as a weekend project. He published it free on the web with its code open for anyone to copy, and more than four million people visited it in its first week.

Cirulli was open about where the idea came from. His game was based on 1024 by Veewo Studio, which was itself a take on Threes!, a mobile game by Asher Vollmer and Greg Wohlwend released a month earlier, in February 2014. Threes! had taken its makers 14 months to develop, and they later published a long log of that work. In it they said they had tried tiles that double when they merge, as in 2048, and dropped the idea because it made the game too easy.

Thousands of versions of 2048 followed, with different board sizes, themes and rules. The original 4×4 version with numbers is still the one most people play.

How the game works

Every move slides all the tiles as far as they go in one direction: up, down, left or right.
When two tiles with the same number collide, they merge into one tile worth their total. Each tile can only merge once per move, so a row of 2 2 2 2 slid left becomes 4 4, not 8.
After every move that changes the board, a new tile appears in a random empty square. It’s a 2 nine times out of ten, and a 4 otherwise.
Make a 2048 tile to win. You can keep going after that for a higher score.
The game ends when the board is full and no two neighboring tiles match.

How scoring works

Every merge adds the value of the new tile to your score: two 8s make 16 and score 16 points. That means big tiles are worth far more than they look, because each one includes the score of every merge that built it.

A 2048 tile built only from 2s is worth 20,480 points. Since some new tiles arrive as 4s (which score nothing when they appear), a game that has just made 2048 usually scores a little over 20,000. It also takes a lot of moves: each move adds about 2.2 to the total on the board, so getting the 2,048 needed takes roughly 900 to 1,000 moves.

The corner strategy

The idea is simple: pick a corner and keep your biggest tile in it for the whole game. Everything else follows from that.

A big tile in the middle of the board splits it into pieces and blocks merges on every side. A big tile in a corner only touches two other squares, and the rest of the board stays open for building the next tile up.

1. Choose a corner and two main moves

Pick any corner. In this guide it’s the bottom-left, which means your two main moves are down and left: both push tiles toward the corner. Use them for almost every move.

2. Use the third move only when you have to

When neither down nor left does anything, use right. It moves tiles away from the left edge, so if your bottom row has a gap, the corner tile can slide out. That’s why the next step matters.

3. Avoid the fourth move

Pressing up lifts your bottom row away from the bottom edge, and the new tile will often drop into the corner you’ve been saving. Only press up if nothing else moves at all.

4. Keep the bottom row full

If every square in the bottom row has a tile, pressing right can’t move any of them, so your corner tile stays put. A full bottom row is what makes right a safe move.

5. Build a snake toward the corner

Line up your tiles from biggest to smallest, starting in the corner and running along the bottom row, then back the other way along the row above. It looks like a snake:


2
8	16	32	64
1024	512	256	128

Each tile sits next to the one it will merge into. When the 8 becomes 16, it merges with the 16, which merges with the 32, and so on along the chain toward the corner. Done well, one small merge can set off a run of them that ends with your corner tile doubling.

6. Merge toward the corner, not away from it

When two matching tiles could merge in more than one direction, pick the move that leaves the result closer to your corner and next to the tile it should join. It’s tempting to grab any merge you see, but a merge in the wrong place leaves a mid-sized tile stranded where it’s hard to reach.

When things go wrong

Sooner or later you’ll be forced to press up or right, and a small tile will land in your corner. Don’t panic:

Move the big tile back straight away if you can. Often the very next down or left puts it back in the corner.
If you can’t, build up the small tile that’s in the way until it can merge with its neighbors, or change your corner to the nearest one the big tile can reach. Switching corners once is fine; switching back and forth isn’t.
Watch the second row. Most games are lost because the row next to your snake fills up with small tiles that can’t merge. Clear it before it fills.

A few more tips

Slow down. There’s no timer. Before each move, look at where the new tile could appear and whether it could get stuck.
Keep small tiles together. A 2 surrounded by big tiles can take dozens of moves to clear.
Don’t chase a big merge far from the corner. Two 128s on the far side of the board can wait until the snake reaches them.
Count the empty squares. If you’re down to two or three, stop building and make merges that open space.

How high can you go?

The game doesn’t stop at 2048. Keep the same corner and snake, and 4096 and 8192 are within reach for patient players. Computer programs that look ahead several moves go far beyond it: the best ones make a 16,384 tile in nearly every game. In theory, the biggest tile you can ever make on a 4×4 board is 131,072, though no person is likely to get there by hand.
