I want to explain a timer cube of a drop cube in detail here.
Perhaps I think that a person nearly a half does not understand a law to explain now.
It is the explanation that how a timer cube falls when the following figures disturb any color.

It is the upper law that 4 decline when they disturbed the color commonly, but blue is scattered most and falls.
The next is yellow; serve, and there is the tactics such as blue towers because is ...
The next is explanation of the super crash.

















The super crash becomes (I do three times of chains) and the super crash to feel three star gauges and falls separately by all means. The good person drops it only in super crash.
I think that I advance naturally if I understand this law.
