Merge Drop

Drop orbs into the tank and touch two of the same colour together to fuse them into something bigger, before the pile reaches the dashed line.

Merge Drop

Drop an orb, then drop another of the same colour onto it. Matching pairs fuse into the next orb up, and the pile only beats you when it sits above the dashed line for a second and a half.

How the tank fills

Orbs fall, settle where they land, and wait for a twin. Touch two of the same colour together and they fuse into the next orb up: bigger, heavier, worth more. Everything else on the board sits still until you give it a reason to move.

Why the chain is worth it

A small double near the floor is worth ten points. Carry the chain to the top of the ladder and one fusion pays more than everything you managed in the first minute. That is the whole trade: quick points now, or a tidy floor and a big payoff later.

One honest tip. Park your largest orb toward a corner and build around it. Anything resting above the dashed line for a second and a half ends the run, so keep the top of the tank clear while you are hunting for a chain.
