Hi, Riad!
Do I understand that the puzzles in the semifinals were printed on both sides? Tell us about the puzzles in the final.

Yes, all puzzles in the semifinal (Полуфинал) were two-sided.
In final (Финал) Andrey Bogdanov, Alexander Ershov and Dmitry Gryshchenko solved 5 puzzles, which form a loop (Snake - Magic Quarters - Clouds - Battleship - Tents). Right solution of previous puzzle gave a hint for the next. Each finalist chose a puzzle to start. Andrey chose to start the puzzle "Clouds", Alexander - "Battleship", and Dmitry - "Snake". The final puzzles contained an element of innovation too - solver had to outline correct 9x9 area in 11x11 grid and then solve the puzzle. As a result Dmitry after 28 minutes completed one puzzle, Alexander after 29 minutes - three. Andrey spent 30 for four puzzle and won the Moscow Cup at the second time.
