Power-Up Panels is a minigame found in every red Toad House from New Super Mario Bros. Wii. It takes place in a room with a six by three grid of panels decorated with question marks. The back side of each has an image of an item, Bowser, or Bowser Jr. Players must take turns climbing around the fence and punching the panels, causing them to flip and reveal their backsides. However, if two Bowser images or two Bowser Jr. images are matched, the player loses. Additionally, 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 set of two identical panels with revealed faces.
"Punch panels with 1 to flip them! Match a pair to win! Match two of those (Bowser/Bowser Jr.) and it's all over!"
This is all the possible combinations for the Power-up Panels in each world. Green colors are indicated to be safe spots.
