when you do

self.class.send(:attr_reader

you apply attr_reader to all objects of that class, but you need that attributes only in one object
some useful docs are here https://ruby-doc.org/ (look for Core API and there for Class, Module, Object, Basic_Object articles)

Nice one !

Nice one

Great solution

Thanks for your kind feedback :)

Hi,

I could not figure it out myself by using Regex but looking at the solution made me learn.

I will keep this in mind as it can be a very nice method to find repeated patterns in strings.

beautiful

Nice one.

Again a very nice Kata.

Explanation were clear.

Some solution in Ruby are very elegant.

Wow! This is a beautiful solution. With some recursion isn't it? (In the play instance method)

I have difficulty to implement such approach because definitively you need to come back to lines to complete it unitl filling all the squares.
And recursion is a good way to do this.

Not having CS background can you tell me if this is what is called backtracking?

In my code proposal I used this false - true - false structure wrapped into a loop.

But yours is so much more clever and elegant.

Thx. Will keep a copy of it and work through it.

cheers

Thank you :-)

I just passed by to say many thanks for this kata.

I upvoted this.

Cheers

My pleasure! All hhe best
