What do Zaroff's remarks suggest about how he himself will behave later in "The Most Dangerous Game"?
Zaroff tells Rainsford that he enjoys the sport of hunting (the "game") once more since he can match his wits against that of another person.This is finally stimulating because a human being can reason instead of simply acting by instinct or out of fear.
For this reason it does not surprise the reader when Zaroff lets Rainsford get away when he is hiding up in the tree instead of shooting him down straight away; he wants to "play" with him and see what he will do next to "escape."
When Zaroff goes back to his house to bandage his wound, he resorts to using the help of Ivan his henchman and finally, his dogs. He had mentioned to Rainsford earlier how indispensible they were to him, so this move can also be anticipated. This seems to be an unfair match, but in the end Rainsford "wins" after all. He is smart enough to realise he can't really escape from the island, so he doubles back to Zaroff's castle, profiting from the fact that the dogs are absent since they are out tracking him down.
Finally, it is Zaroff's procrastination, pride and curiosity which "do him in" in the end. He underestimates Rainsford's intelligence and becomes his prey (or "game") instead.
