Merge Game: Distinct Coin

This is a composite game where currency of the same size and color are grouped together to get a larger currency.

Tap the screen, and the game currency will fall with the place you tap.
What you need to consider is how to place the game currency so that the smallest game currency can become larger game currency after we control each other to collide and synthesize.
PS: When the game currency are piled up beyond the specified space, it will fail, so you must consider the location where the game currency fall!

Believe in your own strength, and you can become a master of synthesis!
