STEP 1 · ENTER BOARD
Your current 4×4 board
Use 0 for an empty cell. Valid tiles are powers of two from 2 to 131072.
Try a position
The next tile appears randomly, so the result is a transparent heuristic—not a guaranteed perfect move. Your tile values stay in this browser and are never included in analytics.

TRANSPARENT SCORING
What the coach measures
Empty cells
More space usually gives future tiles and merges room to move.
Merge value
Immediate points and remaining adjacent pairs reward useful consolidation.
Corner control
Keeping the largest tile in a corner supports a stable edge chain.
Tile order
Smooth, monotonic rows and columns are easier to combine than scattered peaks.
For lookahead, the coach tries a 2 or 4 in every empty cell using the usual 90%/10% weighting, then evaluates the best legal reply. It does not search the full game tree.
Movement rules follow the original open-source 2048 implementation ↗. The evaluation heuristic is explained above and is independent of that project.
FREQUENTLY ASKED QUESTIONS
2048 Strategy & Analyzer FAQ
How does the 2048 board analyzer choose a move?
It applies the standard slide-and-merge rules to all four directions, discards moves that do not change the board, and compares immediate merge points, empty cells, merge opportunities, smoothness, monotonic order and whether the largest tile stays in a corner. It also evaluates one expected random-tile step ahead.
Does the recommendation guarantee the best 2048 move?
No. A new 2 or 4 tile appears randomly after each move, so no short analysis can guarantee the globally optimal play. The coach explains its heuristic and lets you inspect every legal preview.
Is my 2048 board uploaded?
No. Board calculation and optional last-board storage happen inside the current browser. Tile values are not sent with analytics.
