how do you beat level 18 of the android game 100 floors?

Level 18 of 100 Floors is less about solving a complex puzzle and more about speed and dexterity.

Looking at the design on the doors there appear to be 2 half almost-squares, and 5 bluish squares; you can ignore the white shapes, they are merely a distraction.

The bluish squares are buttons that light-up, and the goal is to have them all lit at the same time.

Each time you tap one it lights up for only a second or so, so you have to very quickly tap all 5 of them, and if one goes out, try to re-tap it before another goes out, or start again.

Overall it's not very complicated, but it may take a few tries to get it.

100 Floors was originally released for the iPhone in early May, and was quickly updated from 30 levels to 80 levels by version 1.4 in mid June.

Not long after the iOS release the game was ported to Android devices so that nearly everyone with a smartphone, tablet (iPad, or even iPod Touch) can get in on the puzzle-solving-fun.
