Based on the classic Chinese “dissection” puzzle game tangram, you’re given the silhouette of a large, angular shape, plus seven smaller, angular puzzle pieces from which to recreate it. The smaller pieces can’t overlap, and they also can’t exceed the boundaries of the silhouette.
While the full version of TanZen provides over 200 different puzzles—more are promised for an upcoming update—you can get a taste of the concept in the 18 puzzles of Lite, which will be enough for some players to fully sate their tangram needs.
Thanks to the iPhone’s touchscreen and the developer’s use of simple one- and two-finger gesture commands, the process of selecting pieces, moving them, and rotating them is completely intuitive; the only challenge is figuring out how to do this properly for each of the puzzles.
The fact that there’s no audio doesn’t bother us much given the price and nature of the game; this is one of those titles that provides nice background entertainment as you’re listening to iPod music.
