2248 tile chart
Every tile value in the game, how large numbers are written, how chains are rounded and when small numbers retire.
Every tile is a power of two
All tiles in 2248 are powers of two: each value is exactly double the one before it. The smallest tile is 2. There is no upper limit, but numbers soon get too long for a small tile, so from 16,384 on the game writes them with a letter. Each value has its own color in a cycle of 12 colors, so 2 and 8192 share a color. From 1024 on, tiles also get a soft glow so that a big tile stands out on the board.
Note that 2248 is not one of the values: it is the name of the game, taken from the chain 2, 2, 4, 8. After 1024 comes 2048.
K, M, B and T
Tiles up to 8192 are shown with all their digits, so 1024, 2048 and 4096 appear in full. Larger tiles use a letter, and each letter stands for a factor of 1024, not 1000:
- K = 1024. 16K is 16 × 1024 = 16,384.
- M = 1024 K = 1,048,576.
- B = 1024 M = 1,073,741,824.
- T = 1024 B = 1,099,511,627,776.
The same letters are used on the tiles in every language of the game. Your score is different: it is shown as a full number, such as 12,345, and is shortened only when it reaches a trillion.

Rounding table
A chain merges into the smallest power of two that is at least the sum of its tiles. If the sum is already a power of two, nothing is rounded. Your score grows by the value of the new tile.
| Chain | Sum | New tile |
|---|---|---|
| 2 + 2 | 4 | 4 |
| 2 + 2 + 2 | 6 | 8 |
| 2 + 2 + 4 | 8 | 8 |
| 2 + 2 + 4 + 8 | 16 | 16 |
| 4 + 4 + 4 | 12 | 16 |
| 2 + 2 + 2 + 2 + 2 | 10 | 16 |
| 8 + 8 + 16 + 16 | 48 | 64 |
| 4 + 4 + 8 + 16 | 32 | 32 |
| 8 + 8 + 8 + 8 + 8 | 40 | 64 |
| 128 + 128 + 128 | 384 | 512 |
| 32 + 32 + 64 + 128 + 256 + 512 | 1024 | 1024 |
The table shows two useful patterns. A ladder in which each tile doubles the one before, started by a pair, always adds up to exactly the next power of two. And a group of three equal tiles gives the same result as a group of four.
When small numbers retire
New tiles that drop in from the top are drawn from a range of six values. Small values are the most common, and the largest value of the range is rare. At the start of a game the range is 2 to 64: about 40% of new tiles are 2s, and only about 2% are 64s. The start board itself holds only 2s, 4s, 8s and 16s.
When your highest tile reaches 2048, the range moves up by one step, and the 2 retires: every 2 on the board leaves with a short animation, the empty cells refill from the top, and a message tells you which number has retired. From then on, each time your highest tile doubles, the next small number follows.
| Highest tile reached | Retired | New tiles |
|---|---|---|
| up to 1024 | none | 2 to 64 |
| 2048 | 2 | 4 to 128 |
| 4096 | 2 and 4 | 8 to 256 |
| 8192 | up to 8 | 16 to 512 |
| 16K | up to 16 | 32 to 1024 |
| 32K | up to 32 | 64 to 2048 |
The rule is simple: once your highest tile is 2048 or more, the smallest tile on the board is your highest tile divided by 512. Retiring keeps the board playable for as long as you can keep finding chains.
Your tile collection
The Statistics window has a strip with every tile value you have reached at least once, from 2 up to your highest tile, each in its own color. The next values are shown as outlines, so you can see which tile is your next goal. For ways to reach the next one, read the tips and strategies, or go back to the game.
