Note!

Do you want to be a detective? Or just want to kill some time?

In this compilation of some... things(?) your going to solve some riddles, codes, chipers and the likes.

It's neither easy and hard so better prepare yourself.

Feel free to write or type your explanation in the comment box. No trash talking please. And some suggestions and critics should be fine.

Enjoy!

PS: some of it is just my idea so better not assume much.
