Doodle Fit is an engaging geometric puzzle app with cool features and awesome flexibility. Kids can choose sketchpad or chalkboard graphics schemes. Gameplay requires them to fit mostly four-unit geometric shapes, with a few one- and two-unit shapes thrown in, into another shape without empty spaces or overlaps -- pretty basic puzzling. Kids drag and drop shapes to place them, tap or drag off to remove, and get hints when they're stuck. Blocks don't rotate, which limits possibilities but probably makes solutions easier since there are fewer options. Kids can skip a level and return to it later.
With 110 levels and multiple solutions for many of the puzzles, Doodle Fit will keep kids solving problems for quite a while. Each puzzle challenges them to study the whole to see where blocks can and can't fit. Early puzzles are quite approachable for second and third graders, but difficulty ramps up quickly.
The app tracks total time and number of moves used to solve each puzzle. It's simple and streamlined, although it does connect to Facebook and has some in-app purchase options. Players can share high scores via the Game Center social network, but participation is optional.
For younger kids, teachers can use this engaging game to reinforce spatial-relations skills. The geometric shapes, ABCs, faces, and star bursts will keep kids playing. The system keeps track of multiple players; make sure to set them up before they start so they can save their solutions.
