Its been three years and I never received an answer on the other comment.
Anyways, I followed your suggestion and provided random tests.
I updated the description, which now needs no change w.r.t. the current kata since it became language agnostic in the meantime anyways.

Ideally I would like some sort of rebase option, since now my diff seems to show it with respect to the status quo three years ago? If you know where I can find something like that, Id be glad to know

Good to know. Is it necessary to specify for c++ separately or would users still be able to see the description?

I also have no idea what is meant by "vertexs".

Just had the same problem. Tried coding exactly what you said. Note also that the test cases sometimes have multiple fours, so I guess determining where the game actually finished is part of the task.
