How to Play 2048 Classic
How to play, sliding tile collision rules, input shortcuts, and the mathematically proven corner-lock algorithm.
2048 Classic is an iconic mathematical puzzle played on a 4×4 grid. Your objective is to slide numbered tiles across the board to merge identical numbers together until you synthesize the legendary 2048 tile.
When you input a direction, all tiles slide as far as they can until stopped by another tile or the grid boundary. When two tiles of identical values collide during a move, they collapse into a single merged tile with double the value (e.g. 2+2=4, 8+8=16, up to 1024+1024=2048). After every valid slide, a new tile (90% chance of a 2, 10% chance of a 4) randomly spawns in an empty square.

Pro Tips & Winning Strategies
The Proven Corner-Lock Technique
Designate one corner (most commonly bottom-right) as your anchor. Keep your largest tile permanently fixed there, and avoid ever swiping UP unless absolutely zero other moves exist.
Build Monotonic Descending Chains
Arrange your bottom row in strict descending order (e.g. 512 → 256 → 128 → 64). When a new high tile is ready, it cascades in a single move without displacing your anchor.
Maintain 4 to 6 Open Spaces
A congested board with only 1 or 2 open spaces leaves you vulnerable to awkward spawns. Consolidate low-value tiles early to keep the board spacious.
Never Pre-Merges in Central Columns
Avoid making impulsive merges in rows 2 or 3 that break your bottom-row monotonicity. Focus on feeding your anchor row from the top.
