Nova Merge 2048

Slide luminous number cores across a 4x4 observatory, fuse equal values, recover accidental moves with bounded undo, and build a 2048 nova in this original responsive number puzzle.

How to play

Slide every tile on the 4x4 board with the arrow keys, WASD, or a swipe. When two tiles with the same number touch, they fuse into one tile holding their sum, and that sum is added to your score. After each move that changes the board, one new tile appears, usually a 2 and sometimes a 4. Build a 2048 tile to reach the milestone, then keep merging until no move is left.

Tips for this game

  • Choose one corner for your biggest tile and swipe toward it most of the time. Keeping large numbers together leaves room for small tiles to merge into them.
  • Each tile fuses only once per move, so a row of 2 2 2 2 swiped left becomes 4 4, not 8. Plan two-step merges instead of expecting a chain.
  • Use Undo when one swipe scatters your big tiles, but treat it as a safety net: it restores one of the last 20 valid moves and is unavailable once the game is over.

Common questions

Is my game saved if I close the page?

Yes. The board, score, move count, and settings are saved in your browser's local storage on this device, so reloading continues the same run. Clearing site data for beannest.net removes the save.

What happens when I reach 2048?

A dialog offers Continue or New Game. Continue keeps the board going until it is full and no two neighboring tiles match; then the final score and your records are shown with a Play again button.

How do I play on a phone?

Swipe on the board in any of the four directions. A swipe needs to be a deliberate, mostly straight drag, so tiny or diagonal drags are ignored instead of causing an accidental move.

What do Next core and Core level mean?

Next core is always double your highest tile. Core level counts the tile 2 as level 1 and 2048 as level 11, so you can see how many doublings remain without a guess about the number of moves.
