2048
Use arrow keys, or swipe on mobile. Combine matching tiles.
Score: 0
Classic sliding-tile rules
Swipe or use the arrow keys to slide every tile in one direction. Matching tiles merge into one with double the value, and a new tile spawns after every move that actually shifts something. Reach 2048 (or keep going past it) before the board fills up.
The corner strategy
The single most reliable technique: pick one corner and keep your highest tile pinned there for the entire game, generally favoring two directions (say, only ever swiping left and up) and using the other two sparingly. This keeps your board organized by descending value radiating out from that corner instead of scattering big tiles across the board where they block each other from merging — most high scores come from discipline about this pattern, not lucky tile spawns.
Where the puzzle actually comes from
2048 was created in 2014 by an Italian developer, Gabriele Cirulli, as a weekend project built on top of an earlier similar game — it went viral almost immediately and spawned an enormous wave of clones and variants within weeks of release, a rare case of a genuinely new puzzle mechanic (rather than a reskin of an existing genre) breaking through that fast. The core rule set here matches the original faithfully: same board size, same merge logic, same scoring.
When to break the corner rule
The corner strategy holds almost all the time, but rigid adherence to "only two directions" eventually creates a board with no legal moves left in either allowed direction — when that happens, using the third direction briefly to create space, then immediately returning to the two-direction discipline, is the correct exception rather than a sign the strategy failed. Treating the rule as a strong default rather than an absolute law is what actually gets a run past the 1024 tile rather than stalling out from a board that's locked itself into a bad shape.
