Ghép Số is live: slide and merge the number tiles to 2048, with a daily challenge for everyone

What is Ghép Số?

Ghép Số (2048) is the classic number-merging puzzle on a 4×4 board: slide every tile in one direction, and two equal tiles that meet merge into one doubled tile — 2+2=4, 4+4=8, 8+8=16… Keep doubling until you build the legendary 2048 tile. It sounds simple, but the real art is keeping the board from filling up: every effective slide also spawns a new tile on a random empty cell.

The rules in 60 seconds

• Slide the tiles: swipe on your phone or use the arrow keys / WASD on a computer. Each slide packs every tile against that side; merged tiles score points equal to the new tile's value.
• One merge per tile per move: a row of 2-2-2-2 slides into 4-4, never straight to 8 — plan ahead before you slide!
• Win and keep going: making the 2048 tile wins the game, but you can play on to hunt 4096, 8192 and ever higher scores.
• When it ends: the board is completely full with no two equal neighbours left — the game is over and your score is recorded.
