Duck: Think outside the flock
Duck: Think outside the flock is one of the few games on Kongregate that I played in its entirety without a badge to reward me. I saw it on the New Games list, and noticed that it was by the same designer as Factory Balls (review here), and hoped that it would be, like Factory Balls, a fun if somewhat insubstantial diversion. And indeed, that is exactly what it turned out to be.
Duck consists of 25 duck-based logic puzzles. Figuring out exactly what the puzzle is is part of the challenge, but generally the puzzle itself is pretty straightforward and self-evident. Some of the puzzles require a bit of careful mouse movements, while some require only brainpower, but none of them is particularly difficult -- you may get hung up on one (perhaps the last one) for a few minutes, but there aren't any particularly sneaky tricks that you need to employ.
The presentation is nothing special -- the ducks are cute, but they all look the same (or almost so). Similarly, the quacking that you get on a successful puzzle completion is cute but repetitive. The music is a selection of tunes from the Nutcracker (why not Swan Lake, I wonder?), which is definitely a step up from the typical Flash game music. Overall, this game is neither difficult nor long, and I wouldn't say it has a huge degree of replay value, but it is charming and fun enough that you should enjoy playing it through once.
