1. How do I play Gem Loop: Royal Jewel Craft?

Tap a front cannon cart in the bottom chutes to launch it around the 3D clockwork conveyor. It harvests matching outer-ring gem cubes! Unused carts park in the 5-slot waiting dock.

2. How does the 24K Gold Winged Prism Merge work?

When two carts of the same color land in the waiting dock, they automatically fuse into a 24K Gold Winged Prism Cart! Tap it in the dock to fire rainbow piercing beams straight through outer blockers.
