Game Summary

Challenge games
 Stair Down: Challengers compete in two heats, half Champs and half Stars each heat. They are covered in lube and must make their way to the top of a flight of stairs. The winners of each heat become the team captains for drafting the mixed teams. Once drafted, the total combined time from each individual player determined which newly formed team with the fastest time was the winner.
 Winners: Blue Team - MVP: Tony
 Over the Edge: Similar to shuffleboard, players must sit on top of a giant puck while another teammate pushes them to score points. Touching the ground while on the puck of going over the edge of the board disqualifies that player.
 Winners: Red Team - MVP: Ashley
 Release the Rainbow: Competitors are connected to a piece of ribbon and must untangle themselves from a giant jungle gym. Players may assist other players on their teams as long as they don't lock their ribbon in its final position. The first team to have all their players untangle themselves and connected to their final puzzle wins.
 Winners: Red Team - MVP: CT
 Face Off: Played on a football field in heats, players take turns on offense and defense. On offense, a player must kick a small ball past the 10-yard line while their teammates try to protect them, by blocking defenders with giant blown up balls. Similarly, the players on defense must stop the offensive player from bringing the small ball back into the endzone by knocking them over with the blown up balls.
 Winners: Blue Team - MVP: Louise
 Jumbo Table Hockey: Contestants play a game of field hockey, however the area they can move around is limited to moving their hockey sticks which are connected to the table. 
 Winners: Blue Team - MVP: Daniel
 Crossfire: Players must divide their teams: half chosen to shoot dodgeballs using slingshots at giant stacks of boxes they must knock over, the other half hanging over the stack of boxes trying to defend them. When a player's stack of boxes is knocked over, they drop down to the ground and then may help retrieve balls for their teammates. The first team to have all the other team's boxes knocked over wins.
 Winners: Blue Team - MVP: Drake
 Go Deep: Partners must dive into an Olympic swimming pool and take turns moving a ring along a series of pipes. The first team to figure out the puzzle and remove the ring from the pipes and return it outside of the pool wins.
 Winners: Brooke & Shane - MVP: Shane
 Spot On: Similar to Twister, players must hold themselves between two walls with colored pegs. They must move their arms and legs to the corresponding colored peg that is called out. If players stop touching a peg, they are eliminated, and the last player remaining wins for their team, while the bottom 3 teams are on the chopping block.
 Winners: Casper & Louise - MVP: Casper
 Text Tile: Similar in style to the "Die Hard" Gulag from Cutthroat, teams must move a large crate across a beach, where one player lifts and moves the crate, while the other balances on top of the crate. Once at a certain mark, players must then open up their crate to find letters for a puzzle. The first players to solve the "Millennial Crossword Puzzle" wins and earn a spot in the final challenge.
 Winners: CT & Tony - MVP: Tony
 Bankroll: In the final challenge, the teams participate in four stations. After each station is complete, teams must collect a coin and deposit it to their "Miz Bank" before moving on to the next station.
 Puck It: Teams must use shuffle sticks to push a tire off an elevated ramp while standing on a balance beam. If a player falls off the balance beam, the team must start over.
 Blockhead: Teams must use a hoverboard to collect block puzzle pieces. Once all the pieces are collected, teams must then assemble a block wall puzzle with the faces of all the cast members.
 Eat and Run: Teams must use star poles to move five balls into a bucket. After each ball is deposited, they may then select a food item. Once all balls are deposited in the bucket, the teams may then eat their selected food items.
 Beat Box: Teams must unwrap, untie, and unchain several layers around a giant box to complete a slider puzzle inside.
Winners: CT & Tony (won $100,000)
Second Place: Casper & Louise (won $50,000)
Third Place: Daniel & Wes
