Level 7 was missing.
At that moment, I really thought my mind was not working properly or that my eyes were tired thus could not find level 7. I calmed myself down slightly and find “7” through the primitive way. I counted the numbers one by one to finally “7”.
Some mischievous person had replace “7” with an inverted number 6 button. Strangely, I did not find it irritating, but thought that it was quite humorous. Good one… But how did they do it?
So, inverted 6 is the new 7. Hmm…There is always new things out there waiting to play with our senses…
