Not sure but seems like the solution is presented right away here... and tests don't seem to be working?

Don't beat yourself up buddy. I may just have been lucky being familiar with some tools that were useful here. And even then I still had to educate myself on some other methods/tools.
I would say just read/learn as much as you can, play with the code, test it and revisit pending katas every once in a while - it will hit you eventually. No one was just born a coder.

5h lucky guy :D. My brain is mashed for month... it looks like I wont be coder so soon :(

I don't remember... Probably I meant that is very important to avoid making solution too complicated bla bla... ;) Eventually look at the comments here: for some people it was quite hard though the idea of kata looked in first moment very easy...

I am but a newbie here however IMHO this kata may be higher level than 6 kyu. Made me stretch my brain for 5h straight and ended up writing 23 lines of code LOL.
The satisfaction though!!! Thank you!!!

"Pretty confusing instructions for a newbie like me. No clue what to do here..."
UPDATE: Took me 2h to figure out what is required and further 8h to educate myself on object creation, constructor finction etc.
The satisfaction was overwhelming and educational experience unquestionable. GREAT KATA!!
