Python: this should not pass.

Add some useful it block for anti cheat tests.

Removed.

That app took it from Battleship, which was produced by Milton-Bradley starting in 1967.

I’m not entirely sure, to be honest.

why would some commercial mobile app need to be credited in the kata for a game that far predates said app? can we not do that.

Nah, it won’t happen—I’ve added a line in the description to cover it.

The instruction 'For each digit d in n, find the dth prime number. (If d=0, use 1)' is confusing. Replacing 0 with 1 suggests we should use the first prime number, which is 2. However, the operation uses 1 instead.

Really enjoyed this, but I think the instructions should clarify the following:

• Can a "hit" ever occur at the same location more than once?
• And if so, how should the solution handle that? In other words, can we assume that the first hit at this location already caused as much damage as possible, or should the new hit cause further damage to the ship?

I don't think so. There are board validators and a few other kata, but not actual bot/player. Some time ago I planned to create one, but never got to it :)

Don't we have this yet on codewars?
