Oh, it was quite simple there. The hint for the role was a personal car with Abba (money-money-money, such an atmosphere). And the clue was a dining room. This is a tributary of the river on which Donetsk is located. It's funny that Toksi managed to find the solution for the Winner through Abba in the chat, although I wouldn't have given such a clue in this game; the clues were easy.
