I have got the dots from the image. But don’t know how to decode it. Searched a lot on the web but no hope. Can anyone give some ideas? Thanks!

HI,

I suggest to change your keywords, you should find everything you need to complete this challenge on the web.
Good luck  🙂

HOW CAN I FOUND THIS ? ANY TOOLS? ANY HINTS..

You can find the meanings of those famous yellow dots in Wikipedia !
Only thing left will be calculating.
