About Merge Lab
Merge Lab is a cozy physics puzzle. Drop blobs into the jar, and when two of the same blob touch they merge into a bigger one. Climb through 11 blob tiers from Spark to Galaxy, and merge two Galaxies for a supernova bonus. Keep the jar below the red line or the run is over.
Each turn you get one blob. Slide it to the spot you want, then let go to drop it into the jar. The blobs have real physics, so they roll off each other, settle into gaps and sometimes bump other blobs into a merge you didn't plan. When two blobs of the same kind touch, they join into the next, bigger tier.
There are 11 tiers, from the tiny Spark all the way up to the Galaxy. Merging two Galaxies sets off a supernova for a big bonus. Watch the red line near the top of the jar: if blobs stay above it for too long, the run ends. Coins you earn can pay for the Pop power-up, which removes one blob when you are stuck.
