Doodle Fit ($0.99). This charming little shape puzzler separates the world, more or less, between those who pack luggage in a car trunk efficiently….and those who don’t. Your job is to fill the oddly configured, empty geometric shapes with smaller component blocks (also oddly configured). Do so by dragging the latter into the former. Sounds easy, and at first it is. But soon these increasingly intricate visual challenges make you realize that playing with blocks isn’t always so simple. The hand-drawn canvas and shapes add to the game’s apparent simplicity, but don’t let that fool you. With 100-plus levels, you can spend hours in DoodleLand.
