About Number Merge

Number Merge is a take on 2048, the sliding-tile puzzle Gabriele Cirulli released in 2014, itself inspired by Threes! — merge matching numbers until you reach a target tile, then keep going as long as there's room to move.

Board size is the difficulty here: Easy plays on a roomy 5×5 grid, Normal on the classic 4×4, and Hard squeezes everything into a tight 3×3 — fewer empty tiles, harder merges.

Tips

• Keep your highest tile pinned in a corner and build around it instead of chasing merges across the board.
• Merge in one general direction as long as you can — switching directions too often scatters your tiles.
• On 3×3, every move matters. A single wrong slide can lock the board.

Every round you finish is checked against the global Number Merge Top 10 above — no account needed, just a name the first time you place.
