Power-up Panels is a minigame that is played in Red Toad Houses in New Super Mario Bros. Wii. It takes place in a room with a six-by-three grid of flip panels decorated with question marks. The back side of each has an image of a power-up, Bowser, or Bowser Jr. Players must take turns climbing around the fence and punching the panels, causing them to flip and reveal their backsides. If two Bowser images or two Bowser Jr. images are matched, the game ends. If all item panels are revealed, the game ends and the characters will rejoice. At the end of the game, players receive one item for every pair of identical panels with revealed faces.
"Punch panels with to flip them. Match a pair to win! Match two of these (Bowser/Bowser Jr.), and it's all over!"
These are all the possible combinations for the Power-up Panels in each world. Green colors are indicated to be safe spots.
