Do you mean that someone very lucky can guess the words without actually solving the riddle? I don't think it is possible for this riddle but it is interesting. I will think about it. Thanks for the idea!

I dont know how to solve it, what do you have to do?

If I write what exactly you need to do it won't be a riddle.
But I can write steps for solving my previous riddles. They have some similarity with this

Maybe this will help you.
