Gravity Merge

A pit that pulls inward

The playing field is a circular pit, and gravity drags everything toward its middle. You travel around the outside and release an orb from wherever you are, and on the way in it curves. It comes to rest where the pull sends it, not where you were pointing, so aiming is about predicting the curve rather than lining up a straight drop.

Climbing the tiers

Any two orbs of the same kind merge when they touch and become one orb of the next tier. Pebble becomes Pearl, Pearl becomes Comet, and the ladder keeps going, eleven tiers up, until it tops out at the Supernova, which shakes the screen when it appears. Every merge also frees up room, because two orbs turn into one.

Combos and the red ring

Merges that follow one another quickly earn combo multipliers, so it pays to release an orb where one merge can set off the next. The danger is the red ring. If any orb settles past it, the run ends on the spot, and one orb is all it takes. That is why the game stresses keeping the pile centred: a heap that grows out to one side creeps toward the ring, and every orb that lands out there brings the end closer.

Reading each drop

Because every orb bends inward, the useful habit is to think about where it will finish rather than where it starts. Look at the pile, find the orb that matches the one you are holding, and choose a spot on the rim whose curve will carry the new one onto it. Quick follow-up merges keep a combo going, and each merge shrinks the pile, which in turn keeps it away from the ring.
