Updated to String[]. Thanks for paying attention!

My point that some people prefere to complite kata with minimum stuff. But input already insist them to use expansions. At other side, you always can easily get dictionary from array, if you want solve it with em.
Anyway, its only my opinon and you made a good translation

Why not to use array of tuples? It seems more native then add Linq, Collections.Generic and Newtonsoft.Json namespaces

Yes, you are right, it is very similar. Unfortunately, I didn't see that kata before.

It is. Only 1, 2 or 3

Anyway, I've expanded the fail message. Seems clearer now.

first "if" will not work because opponent can hit 4

Should I add initial value in fail message? Like Start: 77. Ending: Player 5 -> 4 Opponent 4 -> 0 ? I just don't want make it too easy

Ready. Looks like it's time. Would you mind approving this kata?

Approved.Thank you!

In random block you write log
nail + system_hit + player_hit, nail + system_hit, nail + system_hit, nail
before substracting system hit from the nail, thats why last tic log is
Player: 11 -> 8 Another guy: 8 -> 4 when has to be Player: 7 -> 4 Another guy: 4 -> 0
Unfortunatly I wasn't able to fix it myself because nail - system_hit gave weird results sometimes:
nail + player_hit, nail, nail, nail - system_hit
< Incorrect Result >

Player: 5 -> 3
Another guy: 3 -> 4294967295 max int? C scares me :(

Approved, thank you
