The 2048 corner strategy, explained move by move

Why a corner at all

Every move slides every tile. A tile in the middle of the board can be pushed in four directions, which means your largest number is constantly being separated from the tile it needs to merge with.

In a corner it can only be pushed two ways, and if you avoid one of those it never moves at all. That turns your biggest tile into an anchor that everything else merges towards.

The three direction habit

Say you choose the bottom left. From then on you press left, down and right. Up is the move that drags your anchor off the wall, and one careless press undoes twenty good ones.

When a position looks like it needs up, it almost always needs left and then down instead. Try those first and the board usually unlocks.

Build the row, not the board

Keep your bottom row in descending order: biggest in the corner, then the next biggest beside it, and so on. A row like 256, 128, 64, 32 collapses into 512 in three moves when the right tile arrives.

A row out of order, like 256, 32, 128, 64, cannot collapse at all, and it will sit there eating space for the rest of the game.

Where games actually die

• Pressing up in a panic, which lifts the anchor off the wall.
• Letting small tiles scatter instead of merging them early, so the board fills with 2s and 4s.
• Filling the bottom row with large tiles out of order, which locks them.
• Chasing a big merge at the top of the board while the bottom runs out of room.

When it gets tight

Count before you move. If only one direction keeps the anchor in place, take it even if it merges nothing, because a free square is worth more than a merge that costs you the corner.

If you genuinely have to press up, do it when the bottom row is full and identical in order, so the board rebuilds the same shape immediately.
