Which castle is the most difficult?

Lider1, but what makes the AI so dumb?) It seems to play quite well, bringing in a powerful army.
Can you provide some facts?

The fact is that it's easier to show than to tell. It simply plays poorly. Stupidly. Weakly. And so on. Here, at http://heroes3.tv/, there are streams of Heroes games; watch any stream where people play against the computer. And see how easily it gets defeated. As if by chance, as something self-evident. See how far a human player can develop and how far the computer can.
It's incomparable.

The fact is that it can't do anything. It’s limited to building capitals with two or three heroes. It cannot conduct battles, clear the map, maintain pace, or assess the situation on the map. Noth - ING.

I don't often play Heroes III, and I haven't played online at all (by the way, could you tell me how? It seems like only local multiplayer is available, or am I wrong?).

You can do it this way, or that way. You can arrange matches here; look at the last page and write there.

And by the way, I wanted to ask about Conflux – how often is it used in online games, and is it even allowed in tournaments? As well as Necropolis.

Of course, it is allowed. But with restrictions. More details here:
