The Corner Strategy in 2048
If you take exactly one idea away from any 2048 guide, make it this: choose a corner, anchor your biggest tile there, and never let it leave. Almost every winning game is built on this single discipline, and almost every loss comes from breaking it.
Why a corner at all
In 2048 a tile only merges with an identical neighbour. Your largest tile has no equal on the board, so it can't merge with anything for a long time — it just needs somewhere stable to wait. A corner is the only spot that's touched by just two directions instead of four, so it's the easiest place to keep a tile parked while everything else churns around it.
Pick one corner and commit for the whole game. Bottom-right is a common choice, which means you'll mostly use right and down, and treat the other two directions as emergencies.
Build a gradient toward the corner
The corner tile shouldn't sit alone — line up your next-largest tiles beside it in decreasing order, so the board forms a slope running down into the corner. When tiles are ordered like this, a single swipe slides each one into a same-valued partner and the whole row collapses cleanly. The snake pattern is the full version of this idea.
The one rule: don't break the corner
The fastest way to lose is to swipe in the direction that pulls your biggest tile out of its corner. With a bottom-right anchor, that fatal move is usually up — it can drag the corner tile off the bottom edge and scatter your careful gradient. Guard against it: keep the bottom row full so that swiping down does nothing and your corner can't slip. There's a whole habit to build here, covered in why you should never swipe up.
When the corner fills up
Eventually the corner row fills with tiles you can't yet merge. Don't panic-swipe. Work the opposite side of the board to generate small tiles and feed them in gradually, always swiping back toward the corner afterwards so nothing drifts. Patience here is what carries you from 512 to 1024 and into the endgame.
