2048 Math — Merge Tiles and Learn Powers of 2

2048 Math is a free version of the classic 2048 sliding-tile puzzle with a math twist. Slide the tiles, merge equal numbers, and build your way up to the 2048 tile. Switch on Powers view to see every tile written as a power of 2, or turn on doubling hints to watch each merge as an addition fact. No account or download is needed, and your game saves automatically in your browser.

How to play 2048

1. The game starts with two tiles on the board. Each new tile is a 2 (nine times out of ten) or a 4.
2. Choose a direction. Every tile slides as far as it can that way, and then one new tile appears in an empty square.
3. When two tiles with the same number touch, they merge into one tile worth their sum: 2 + 2 = 4, 4 + 4 = 8, 8 + 8 = 16, and so on. A tile can only merge once per move.
4. Reach the goal tile to win. On the standard 4×4 board the goal is 2048. After you win you can keep going for a higher score, or finish and collect your stars.
5. The game ends when the board is full and no two neighboring tiles match.

If three equal tiles line up in the direction you slide, the two tiles closest to the wall merge first. A full row of four equal tiles becomes two merged tiles.

Controls

• Keyboard: arrow keys or W, A, S, D. Press U (or Ctrl/Cmd + Z) to undo.
• Touch or mouse: swipe or drag across the board. The page does not scroll while you swipe on the board.
• Buttons: on-screen arrows, plus Undo, Swap, New game and Finish.
• Undo: takes back your last move. You start each game with one undo and earn another each time you make a new highest tile of 128 or more.
• Swap: press Swap, then tap any two tiles to trade their places. You start with one swap and earn another each time you make a new highest tile of 256 or more. Press Esc or Cancel to leave swap mode.

Strategy tips

• Pick a corner and stay loyal to it. Keep your biggest tile in one corner and build the row next to it in decreasing order, like 256, 128, 64, 32.
• Use mostly two or three directions. For a bottom-left corner, favor Left and Down. Only press Right when you have to, and press Up only as a last resort.
• Keep your strongest row full. A full row cannot slide out of place, so your big tiles stay put.
• Plan merges in chains. Two 32s make a 64, which can join another 64 to make 128. Line up equal tiles so one move sets up the next.
• Save your undo and swap. They are most useful when a stray 2 lands in your corner.

What 2048 teaches: powers of 2 and exponents

Every tile in 2048 is a power of 2. Choose a Number view above the board:

• 2, 4, 8: the classic look, with plain numbers.
• 2¹, 2², 2³: Powers view shows each tile as 2 raised to an exponent. 16 appears as 2⁴ because 2 × 2 × 2 × 2 = 16.
• 8+8=16: doubling hints show the addition fact above every merge.

In Powers view you can see the rule behind the game: merging two equal tiles adds 1 to the exponent, so 2³ + 2³ = 2⁴. That is the same as saying 8 + 8 = 16, or 2 × 8 = 16. The goal tile 2048 is 2¹¹, and building it takes the equivalent of 1,024 tiles of 2.

The Did you know? panel shows a new fact each time you reach a higher tile. For example, 64 = 2⁶ is the number of squares on a chessboard, and 1024 = 2¹⁰ is why a kilobyte is 1,024 bytes. The colored ladder under the fact shows which powers of 2 you have already reached.

Settings and scoring

• Board size: 3×3 (goal 512), 4×4 (goal 2048) or 5×5 (goal 4096). Each board size saves its own game in progress and its own best score.
• Score: every merge adds the value of the new tile. Merging two 64s adds 128 points.
• Stars: when you finish, you earn 3 stars for reaching the goal tile, 2 stars for half the goal (1024 on 4×4), and 1 star for one-eighth of the goal (256 on 4×4).
• Progress: each game earns XP toward your Effortless Math player level and daily goal. You can collect 8 stickers, such as making 2048 without using undo or making 256 on the tiny 3×3 board.
