MergeMaster

Click adjacent identical numbers, double them, and chase the biggest tile you can build before the board runs out of space.

MergeMaster is the kind of game you open for two minutes and accidentally lose twenty to. The board starts with a scattering of small numbers — 2s, 4s, maybe a few 8s if you're lucky. Click two identical adjacent tiles and they collapse into a single tile worth their sum. That 2 and 2 becomes a 4. The new tile sits where one of the old ones was, and suddenly other pairs line up. The catch? Space runs out fast. I've had boards where the top-left corner was packed with 16s and 32s while a single useless 2 sat stranded in the middle, blocking everything. You start to think in chains: merging a 4 into an 8 might expose a matching 8 right behind it, then that 16 can merge with another one two tiles over. The clicks feel crisp, almost like popping bubble wrap, and there's a little rush when a cascade doubles three times in a row. It's not just reaction time either. There's a slow-burn strategy to deciding which pairs to merge first. Do you clear the smallest numbers to keep paths open, or gamble on building a huge tile before the low numbers wall you in? I kept going back after each dead board, convinced the next layout would let me hit 512. Spoiler: it rarely did, but that's exactly why I couldn't stop.

Mouse click to play.Players aim to combine larger numbers by clicking on adjacent identical numbers on the main game board to eliminate them and create a new number twice as large.

Clear your smallest numbers first whenever possible — 2s and 4s clog corners faster than you'd expect. Before clicking a merge, check if the new doubled tile will match anything next to it. That's a free extra move. Avoid trapping a high-value tile between two dead spots; merged tiles only move into one of the old positions, not anywhere you want. If you see three identical tiles in a small cluster, merge the two that leave the third one reachable instead of sealing it off. Don't be afraid to reset mentally; sometimes a fresh board beats trying to save a hopeless position.
