Doubler
Slide and merge matching tiles to double your way toward a bigger number.
How to play Doubler
Every move slides all sixteen tiles as far as they can go in one direction — up, down, left or right — at once.
When two tiles of the same number bump together they merge into one tile worth their sum, and that sum is added to your score.
After each move that shifts the board, a new tile appears in a random empty cell — usually a 2, occasionally a 4.
Keep merging to build bigger numbers. Reach the 2048 tile to win, then keep going for a higher score; the run ends when the board is full and no merge is left.

Tips
- Pick one corner and keep your biggest tile pinned there — most players anchor the bottom-right.
- Favour two directions (say, down and right) and avoid the opposite ones so your big tile never wanders.
- Build a descending row or column next to your anchor so merges chain in one sweep.
- Don't chase every small merge — keep empty cells free, because a full board with no pair is game over.
About Doubler
Doubler is Navritto's take on the number-merge puzzle made famous by 2048, rebuilt to play instantly in the browser. Each swipe slides the whole 4×4 board and fuses matching tiles into their double, so a screen of small numbers steadily climbs toward the 2048 tile — and beyond, if you keep your nerve. It needs no install or account, works with the keyboard or touch, and saves your best score on your device. Doubler joins Coil in Navritto Games and shares the same feel — the slide, the pop, the glow on every merge — that runs through them all.
