Jewel Synthesis

Tap the screen, and the gems will fall with the place you tap.
Are you curious what better looking gems will come next? Then think about where to place your gems!
Let the gems slide naturally and then collide with the same gems, and use the limited space to get brighter and bigger gems.

Note: Please don't let the gems overflow the screen!
Continuous synthesis, refreshing feel, eliminate stress, and enjoy the rewards brought by gemstones!
