🧩 4x4 Sliding Guide

Slide Tiles to Merge Matching Numbers

Swipe or use arrow keys to slide all board tiles simultaneously. When two tiles containing the exact same number bump into each other (like 2 + 2), they fuse into a single tile with double the value (4)!

1Slide tiles Up, Down, Left, or Right with arrow keys or swipe.
2Collide matching numbers (2+2=4, 4+4=8, 8+8=16) to combine them.
3Keep open cells clear and build toward the ultimate 2048 tile.

📖 How to Play

  • 1.Use your Arrow Keys (or swipe on touchscreens) to slide all board tiles simultaneously.
  • 2.When two tiles containing the exact same number collide, they combine into a single tile with double the value.
  • 3.Every valid slide generates a new tile (either a 2 or a 4) in an empty square.
  • 4.Plan ahead to prevent the board from getting locked with unmergeable tiles!

💡 Master Corner Strategy

  • ✓Choose a Anchor Corner: Pick one specific corner (e.g. bottom-left) and build your largest numbers there.
  • ✓Limit Swipes to 2–3 Directions: If your anchor is bottom-left, primarily swipe Down and Left. Avoid swiping Up unless unavoidable.
  • ✓Keep Rows Sorted: Maintain descending order along the edge (e.g. 1024, 512, 256, 128) for smooth cascade merges.

Frequently Asked Questions

How do you win Number Merge?

You win by combining matching tiles until you successfully create the legendary 2048 tile! After reaching 2048, you can choose to keep playing to achieve an even higher score.

How do mobile touch controls work?

Simply swipe your finger across the board in any of the 4 directions (Up, Down, Left, or Right). The board prevents accidental page scrolling so your swipes are completely smooth.

What happens when the board fills up?

If all 16 cells are filled and no adjacent tiles share the same value (no valid merges remaining), the game ends and your final score is recorded.
