1-Up Chamber
1-Up Chambers,[1][2] or 1-Up Rooms,[3] are hidden areas that appear in Super Mario World. They are accessed through a certain Warp Pipe in some levels, with Donut Plains 1 being the first level to have a 1-Up Chamber. 1-Up Chambers consist of five horizontal floorboards, each with three ? Blocks within them. If Mario or Luigi jumps onto a floorboard, he cannot return to the one below him. The topmost floorboard has a Warp Pipe leading back into the main level.
With each tier, the goal is for Mario or Luigi to jump at the ? Blocks in a certain order, which is always randomized. If Mario or Luigi jumps at the correct first and second ? Blocks each, he earns a coin, followed by a 1-Up Mushroom in the third ? Blocks. Jumping at the first one or two ? Blocks in the correct order turns each one green with a white circle. If Mario or Luigi jumps at a ? Block in the incorrect order, every ? Block in its row turns into an Empty Block.
As Caped Mario or Caped Luigi, there is a method in which he can always hit each row's ? Blocks in the correct order. To do so, he must perform a Spin Jump on the left side of each ? Block from left to right.
