Merge Numbers

How to play Merge Numbers

Merge Numbers is a fast, tactical number puzzle built around a single idea: drop the tile you are given into the column of your choice, then watch equal numbers snap together and double. It is not a swipe game — you never slide the whole board. Instead each tile obeys gravity and falls to the bottom of the column you pick, exactly like a stacking game. The moment it lands it looks at its neighbours, and if it is touching an equal number the two combine into one tile of double value. That new, bigger tile then checks its own neighbours, so a single well-placed drop can set off a satisfying chain reaction that clears half the board at once. The rules take seconds to learn, but planning cascades and keeping your columns tidy gives the game real depth.

The goal

Build ever-larger tiles by merging equal numbers, and be the first to create the target tile for your difficulty — 512 on Easy, 1024 on Normal, 2048 on Hard. Reaching the target wins the round, but the game does not stop there: you can keep dropping tiles to push your score as high as you can before the board fills up. The game only ends when every column is full and there is nowhere left to drop, so the real challenge is surviving as long as possible while chasing bigger and bigger numbers.

Board sizes and difficulty

Three difficulties change the board and the tiles you are dealt. Easy uses a roomy 5-wide, 7-tall board and only ever hands you 2s and 4s, with a target of 512. Normal is 5 wide and 8 tall, adds the occasional 8 to the queue, and asks for 1024. Hard is a wider 6-column, 8-row board that can deal you 2s, 4s, 8s and even 16s, with a demanding 2048 target. Wider boards give you more room to sort tiles by size; taller boards let stacks grow before they overflow; bigger starting tiles mean faster progress but less room for error.

Controls

• Tap or click a column — the current tile drops straight down into that column and lands on top of whatever is already there. This is the only move in the game.
• Number keys 1–6 — on a keyboard, press the digit for a column to drop instantly into it.
• Arrow keys and Space — use ← and → to move the drop cursor between columns and Space, Enter or ↓ to release the tile. Everything works with touch, mouse or keyboard.

The rules

• You always hold one tile, shown in the "Now dropping" slot, with the following tile previewed as "Next". Choose any column that is not full and drop the tile; it falls to the lowest empty cell of that column.
• When a tile lands it checks its four orthogonal neighbours (below, left, right, above) in that fixed order. If it is touching a tile of equal value, the two merge: your tile doubles and the neighbour disappears. Only one pair merges at a time, so values always stay powers of two.
• After a merge, gravity settles the affected columns and the newly doubled tile checks its neighbours again. If it now touches another equal tile, it merges once more — this is the cascade, and long chains are where the big scores come from.
• Dropping into a full column is not allowed; the tile stays in your hand and nothing changes, so a mis-tap costs you nothing.
• The round ends only when every column is full to the top with no legal drop remaining. There is no time limit — take as long as you like over each placement.

How this differs from classic 2048

Classic 2048 is a swipe game: you push the entire board in one direction and every eligible pair in every row or column merges at once. Merge Numbers keeps the "equal numbers double" idea but changes everything around it. You control tiles one at a time from a preview queue rather than reacting to random spawns; you drop into columns under gravity instead of sliding the whole grid; and merges spread as a chain from the single tile you just placed rather than sweeping a whole line. The result plays much more like a drop-and-stack puzzle than a slide puzzle — placement, column management and setting up cascades matter far more than picking a swipe direction.

Scoring

• Every merge adds the value of the new, doubled tile to your score. Merging two 64s into a 128 adds 128 points; a cascade adds each step in turn, so a long chain can add thousands from one drop.
• Higher scores are better, and your best result on each difficulty is stored on your device and shown as "Best on device". Sign in to send ranked scores to the leaderboard.
• Scores are capped at 99,999, which is comfortably more than a strong run of any difficulty will reach, so you never have to worry about the number overflowing.

Strategy tips

• Keep one column low. A relief column that you leave mostly empty gives you somewhere safe to park an awkward tile without triggering a merge you do not want.
• Sort by size. Try to keep your biggest tiles along one side and small ones on the other. Ordered stacks make it far easier to line up the next merge instead of trapping a big tile behind small ones.
• Set up cascades. The best drops do not just merge once — they land so the doubled tile immediately meets another equal number, and then another. Look one or two merges ahead before you release.
• Use the Next preview. Always glance at the upcoming tile. If a 4 is coming, it is often worth placing your current tile to build a spot the 4 can complete.
• Do not fill your escape routes. Overflowing columns are what end the game. When several columns are getting tall, prioritise drops that merge and shrink a stack rather than ones that only pile tiles higher.
