Coinball-Drop Synthesis

In this game, you will spend your leisure time excitedly.
This game can test and exercise your attention and reaction speed.
The game is simple to operate. In the screen, you will see a playing field with numbered coinballs. A single ball will appear above it. Using the control keys, you will have to move the coinball above in the desired direction and place it on the coinball with exactly the same number to synthesize. When it is ready, throw it down immediately. The coinballs collide with each other and merge together. A coinball with a larger number will be synthesized. Come and try it.
