The big twist of the second season of Big Brother Zamolodchikova is the duo twist, which lasted for 4 weeks. Upon entering, each houseguest was given a random duo partner. The houseguest who won Head of Household will be the one who makes the nominations, but they cannot nominate their own duo partner. Nominations have to take place in duos, meaning that you could only nominate one duo for nomination. If the Power of Veto is used, both nominees are taken off the block, and the Head of Household has to name a new duo to be put up for eviction. Eviction goes underway as normal, but the houseguest who stayed will receive a golden key which makes them safe until the end of week 4/start of week 5. They are not allowed to compete in any Head of Household or Power of Veto competitions until week 5, if they receive a golden key.

Another big twist that happened on week 5 was that the first 4 houseguests evicted had a chance to come back. The four first evicted houseguests competed in the BattleBack competition, where they each faced off, and the houseguest who finished in first re-entered the game. The eliminated houseguests were held in sequester until the end of the BattleBack competition, and the 3 houseguests who did not win the BattleBack competition got sent home for good.
