Number Merge

How to play Number Merge

1. Look at the grid of numbered tiles and pick a direction to push them all at once.
2. Slide the whole board left, right, up or down — every tile travels as far as it can in that direction.
3. When two tiles with the same number collide, they merge into a single tile worth double, and that value is added to your score.
4. After each slide a new low-value tile appears on an empty square, so the board slowly fills as you play.
5. Keep building bigger numbers while leaving room to manoeuvre — a packed board with no possible merge is the end of the run.
6. Play on for as long as you can; there is no target to clear, only your own high score to chase.

Controls

On a phone or tablet, swipe across the board in the direction you want the tiles to travel — a flick left, right, up or down moves the whole grid. On a desktop, use the arrow keys to push the tiles the same way.

Tips & strategy

• Pick one corner and keep your biggest tile parked there — anchoring your highest number in a corner stops it drifting into the middle and blocking merges.
• Favour two directions, say down and left, and only break the pattern when you have to; a steady rhythm keeps your big tiles stacked neatly along one edge.
• Never swipe toward your anchor corner if it would shove the high tile out of it — protecting that corner is worth more than one quick merge elsewhere.
• Build a descending row beside your biggest tile so equal numbers line up naturally and chain-merge in a single slide.
• Watch how full the board is, not just the next match — if you are down to one or two empty squares, make the move that opens the most space rather than the one with the flashiest combine.
• When the board feels stuck, look for a slide that lines two pairs up at once; clearing several tiles in one move is the cleanest way to buy yourself breathing room.

About Number Merge

Number Merge is a quiet, clever puzzle you can pick up in a second and lose an hour to. Every tile carries a number, and when two equal numbers slide into each other they merge into one tile worth double. Push the whole board in a direction, watch the matches snap together, and your score climbs with every combine.

There is no finish line — you play to beat your own best. Each slide drops a fresh tile onto the grid, so the board is always one move away from getting crowded. The art is keeping space free for your next merge, and the run only ends when there is nowhere left to move.

What makes Number Merge so quietly addictive is the way it rewards planning without ever punishing you with a clock. Each move is small and calm, but the consequences ripple forward — a careless slide early on can leave a stranded tile that clogs the board ten moves later. You are really playing against your future self, tidying the grid now so a big merge is waiting when you need it.

A great run has a satisfying arc. The opening moves are loose and forgiving, then the board tightens and every swipe becomes a real decision, and finally you are nursing a near-full grid, threading one clever merge after another to keep it alive. The moment you push two big tiles together for a number you have never reached before is exactly why you start one more game.
