Ok, but I think you already revealed that in a different (not marked as spoiler) post. Sorry for the trouble.

Finally, an 8kyu that is actually easy (in C# at least)

I haven't completed the kata yet, so I think CodeWars won't let me see/ unflag it unless I complete it.
Plus you are probably able to do it at will for this kata's comments because you authored it.

"Unauthorized: not allowed to un-flag this comment"

That was a fast reply...
Anyways, the comment was hidden, so that doesn't really help all that much.

how do the steps work?
I think it is either 1 or 2, but clearly that is not the case.
if it can be 3, then what are the circumstances?

It does not, it is rather strange and I don't know how to show a screenshot to show evidence.

C# the solution is in the sample tests area and the sample tests are in the solution area

I only took a glance at the description, and
MY LORD THATS A LOT OF NUMBERS! (especially when I start seeing letters like "e" in equations)
how is this not 3kyu?

The description describes what a perfect game (all strikes) looks like, but what does two strikes in a row look like

I agree, but I will say that the issues tag is meant for when the kata's test codes are entirely incorrect, not issues you have with the kata as a whole.
(I am just giving you a heads up, some moderators are not the best at communicating this.)

Nice kata. Very simple and easy to understand.

in C#, the tests are all in one attempt
Test Failed
Assert.That(Calculator.LastDigit(allCases[i].test), Is.EqualTo(allCases[i].expect))
Expected: 1
But was: 0
this means I can't see which test I got wrong, which makes it hard to figure out how to solve the code.

Its fine, I figured it out for the most part.
Thanks for the effort though.

This is more of an in general question, but how do you handle Katas that will test for a default value? I know I am supposed to be the one figuring this stuff out, but I can barely figure out how to use default values to begin with, making it hard for me to get points for even the most simple Katas.
