Just Sort it out, okay.

Super easy to play, here's how:
1. Tap to grab an orb when it's in front of the pin.
2. Tap again to place that same orb back into circulation.
3. Sort the circuits of orbs into their colours.
4. Avoid collisions of all orbs. If any collide, you lose.

50 levels to play through, it starts easy and gets progressively harder and harder. Speeds change, directions change and space is tight. Timing is key, be a ninja.
