What changes on a 5×5 board
Nothing in the rules; everything in the space. Twenty-five cells mean the tiles that make a 2048 (1024 down to 4, plus a new 4) fill only ten of them, so on this page 2048 is a milestone rather than the end. The win screen still celebrates it, then you keep going.
How far you can go
| Tile | Cells it takes | Average moves to build it |
|---|---|---|
| 2048 | 10 of 25 | about 930 |
| 16384 | 13 of 25 | about 7,400 |
| 131072 | 16 of 25 | about 60,000 |
| 2 to the power of 26 | 25 of 25 | the ceiling of the board |
The move column is the tile’s value divided by 2.2, the average worth of one new tile (a 2 nine times in ten, otherwise a 4). Tiles never vanish, only combine, so that is how many moves it takes to bring in enough.
Strategy for 5×5
- Anchor a corner early. Put your top tile in one corner in the first hundred moves and run the next biggest along the bottom edge in falling order, turning back along the second row when the first is full.
- Use the extra row as a workspace. With five rows you can keep two ordered rows and still have three rows to build the next tile in, so you rarely need your fourth direction.
- Plan for length, not survival. On a big board the danger is less a single bad spawn than mid-size tiles piling up out of order. Every few hundred moves, tidy: merge everything that can merge before building higher.
- Save undos for late game. You get three per game; early mistakes on this board are usually recoverable without them.
