Hi there.
The two boxes that are blinking means the they are switching.
Example:
The 0 = Blinking boxes
The \ = Normal box
Say the smiley face WAS in the left box. Now,
0 \ 0
The left and right box blinked, so that means the smiley is in the right box now. ^-^
Just keep track of the swiching smiley and at the end go to the box that the smiley was last at!
