'''1-Up Rooms''',<ref>{{cite|date=Winter 2002|language=en-us|title=''[[Nintendo Power Advance]]'' v.4|page=26|publisher=Nintendo of America}}</ref> or '''1-Up Chambers''',<ref>{{cite|language=en-us|page=40|publisher=Nintendo of America|date=August 1991|title=Nintendo ''[[Mario Mania]]'' Player's Guide}}</ref><ref>{{cite|date=1992|language=en-us|publisher=Nintendo of America|title=Nintendo ''Super NES'' Player's Guide|page=15}}</ref> are [[sub-area]]s that are accessed through certain [[Warp Pipe]]s in ''[[Super Mario World]]''. 1-Up Rooms consist of five horizontal floorboards, each with three [[? Block|Prize Block]]s within it. 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 object is to [[jump]] at the Prize Blocks in a certain order, which is always randomized. If Mario or Luigi jumps at the correct first and second Prize Blocks each, he earns a [[coin]], followed by a [[1-Up Mushroom]] in the third Prize Block. Jumping at the first one or two Prize Blocks in the correct order turns each one into an {{file link|OX Block.png|O/X Block}}. If Mario or Luigi jumps at a Prize Block in the incorrect order, every Prize Block in its row turns into a [[Empty Block|Brown Block]]. The player has a ⅙ chance to get a 1-Up Mushroom from each row of blocks; a ⅓ chance to hit the correct first block, a ½ chance to hit the correct second block, and then the third block, if hittable, will always contain the 1-Up Mushroom.
