Blinking Eye is an entry-level puzzle designed for children ages 6
and up. The puzzle has 20 stationary blocks and a slider that moves
around the puzzle. Each time the slider moves past a block it opens
or closes the blinking eyes it passes by. The object of the game is
to arrange the eyes in a pattern such as all eyes open or closed.
More advanced patterns such as border eyes open and center eyes closed
are also possible. For added difficulty, complete your pattern with
the slider ending up in the lower right-hand corner.
