Big Brother Neo Kingston (season 7)

• Introductory Challenge: Played in two teams in separate heats, one with seven HouseGuests and the other with eight HouseGuests. HouseGuests must individually transport puzzle blocks one-by-one across a beam from one side of a trench to the other side. If the HouseGuest or the block falls into the trench, the HouseGuest must collect the block and return to the start of the beam and try again. Once a HouseGuest has transported all of their puzzle blocks to the ending side of the beam, they must then connect the blocks according to a puzzle blueprint. When they have completed their puzzle their time will be stopped. HouseGuests may assist each other with their puzzles but only after their own puzzle is complete. Once every HouseGuest in a heat has completed their puzzle, the average time of the players will be locked in. The average times of both heats will be compared and the team on the heat with the worst time will then have the HouseGuest in that heat who finished their puzzle last immediately evicted from the Big Brother house. Regiane was the slowest finisher in the slower heat and was shortly after evicted from the Big Brother house.

• Head of Household ("Flying Saucers"): HouseGuests, standing on narrow towers, are pelted with plastic saucers as well as plastic wieners and fake ketchup and mustard. HouseGuests which fell off were eliminated. The first HouseGuest to catch ten saucers or the last HouseGuest standing, whichever occurred first, was named the Head of Household. When all HouseGuests excepting Ken, Jayvee and Lanaiya had fallen off, Ken became the first HouseGuest to catch a tenth saucer and was named the season's first Head of Household.

At the veto meeting, Ken chose not to use the Power of Veto, thus keeping nominations the same.

• Head of Household ("Balls in a Trap"): Each HouseGuest must tilt a flat platform with three cups at the far end such that each of three balls, starting at the near end, rolls along a path on the platform and into one of the three cups. HouseGuests may be working on only one ball at a time, once they have gotten one ball into a cup they move on to their second ball. Each ball must be maneuvered into a different cup. If a ball falls from the platform onto the ground, the ball must be reset to the near end of the platform. The first HouseGuest to sink all three of their balls into the cups will be crowned the new Head of Household. If no HouseGuest has sunk three balls within seven minutes, the HouseGuest which scored the most balls in the shortest time will become the new Head of Household. After four minutes and nineteen seconds, Stephanie landed her third ball became the new Head of Household.

• Hidden Power ("Garden of Even"): Short mathematical equations are spread throughout a garden. Individually, HouseGuests must search through the garden and collect equations which have even numbered solutions. The HouseGuest which collects eight such equations in the shortest amount of time wins the week's hidden power. Ken collected his eighth equation at a time of 2:30 and was awarded the "HoH Block" hidden power which may be used before any one of the next five Head of Household competitions (through week 7) to block one HouseGuest from participating in the competition that week.
