100 Floors has finally updated on July 31st 2012 with level 91 to 100 and it starts us off with an colorful stage. In level 91 of 100 Floors, you will see a number of colors at the top and a paint brush at the very bottom right. You will see a stain glass like wall with 6 panels in the middle as the door.
If you want to beat level 91 in 100 Floors then you must first pick up the paint brush then then brush away the tint of white on the bottom right by rubbing your screen. Once you do you will reveal the number 16, tap in that area and the panels will turn into color panels matching the colors above it.
From the top panel left to right, the colors are as followed
From the bottom panel left to right, the colors are as followed
Upon correctly applying these colors the door will open to Level 92 in your 100 Floors Main Tower game.
