How do you play Gravity Jar?

An orb falls into the jar from the point you aim at. When two identical orbs touch, they merge into the next tier. As the pile rises, you spin the jar 90° to spread the orbs out again.

01
Drop
Aim and release an orb into the jar. The next orb is shown at the top of the screen.
02
Merge
Two orbs of the same colour merge on contact; chained merges grow the multiplier.
03
Spin
When the pile gets dangerously high, turn the jar 90° left or right.

How many tiers does Gravity Jar have?

There are 11 tiers: the smallest is Spark, the largest is Sun. Merging two identical orbs creates the next tier and scores its points. Merge two Suns and both vanish for a 200-point bonus.

What does spinning the jar do?

Spinning redistributes the whole pile in one move. The jar turns 90° in 600 milliseconds, the orbs roll onto the new floor under real physics, and fresh merge opportunities appear. You start each game with 1 spin; every 10 merges earns another, up to a maximum of 3.

When does the game end?

If orbs stay above the death line near the top of the jar for a total of 6 seconds, the game ends. The last 5 seconds are counted down on screen, giving you time to spin your way out. You get one continue per game.
