Also, I don't think this solution accounts for wheel straights either. Basically, just need more test cases to invalidate solutions like these.

Yep. This would make this not a "great solution".

Great solution.
But I'm not quite sure the cheking for straight (numbers_in_sequence) is true.
You check it by the sum of the card, so if you have [3,4,5,6,7] the sum equals 25, so the function returns true.
BUT, if you have [3,3,5,7,7] the sum is the same - 25, so you'll get it as a stright, while it's not.

Then again, exploring your code was a lot of fun! :D

Looking back on it, I could have put some comments in .. :P

Pure awesome, thank you!!

Thanks, I added the second 'abc' test.
I didn't add the '' characters test as there's a valid hash for the empty string.

Ok thanks for checking...

I have no clue. I can't find any either.

It may just be CodeWars acting strangely (again).

Doesn't help to make this kata more complicated...;-) There's a new testcase, so marked it as resolved...

Awesome, thank you for the quick help @rollietikes !
