Blocks fall faster than the average brain can comprehend
The reason people get frustrated at the ga,e is because of the way the brain processes information. Due to the limitations of the average brain, testosterone is produced due to how the brain subconsciously understands that comprehending information that fast is impossible.
I wouldn't recommend it. The average for me is ~40. I have seen others fail at ~20. After multiple rings are added, the brain cannot comprehend data given to it.
Once this happens, people then simply put the blocks through random rings.
This game is not fun, only frustrating, and due to this, will demand a lot of time. This time, however, is futile.
