How do you pass level 12 in 100 floors

Level 12 in the hit new iPhone/iPod Touch game 100 floors is simple to describe, but is a bit tricky to actually do; it may take quite a few tries, but don't give up, it is possible to do.

What you need to do is tap the buttons as quickly and as lightly as you can. It only requires a single tap, but it has to be as short as possible.

When you've tapped either the left or right button just right, the grey ball will reach the top of the column, and the off-white ball at the top will light up green. Once you've turned both of them green, the elevator doors will open and you can proceed to the next level.

The latest upgrade to the game, version 1.1, includes 10 more levels bringing the total to 40 so far. This Dooors-like game successor quickly hit #1 in Apple's App Store, and has fans eagerly awaiting new challenging puzzles to solve.
