The parents' guide to what's in this app.

Educational Value

Kids can learn how to dissect larger shapes into smaller shapes of equal area. Players get a one- to five-star rating if they're successful and can refer to percentages as precise as tenths to try again. Particularly difficult shapes challenge kids to hypothesize about which slices will do the job. Unfortunately, the app never explains that area, not shape, is the goal, so asymmetrical shapes might confuse. Slice It! is a unique app that marries tons of mathematical concepts to really cute graphics and fantastic, adaptive feedback.

Ease of Play

The controls are super-easy (you just slice with your finger), but the puzzles are extremely challenging. They get harder as they go along, of course, but even some of the earlier ones are real doozies. This is not to say they aren't fun, though. And a limited number of hints are available.

What parents need to know

Parents need to know that Slice It! is a challenging puzzle game that requires a mathematical mind and a good grasp of spatial relations. You not only have to slice each shape into a specified number of parts, but you need to do so by making the exact number of slices specified, and you also need to make sure all the pieces are the same size. That means that even if the pieces you cut are different shapes, they still need to have the same area. These are not the kind of puzzles that allow for multiple possible solutions.

What's it about?

Shapes in the game are simple and generally symmetrical, but soon odd numbers of slices and crazy shapes -- like piranha -- pop up to challenge. Kids tap and drag to make their slices. Players fail if they don't use the indicated number of slices or create the right number of shapes. If you get those right, the app tells you "clear," gives you a star rating, and shows you a diagram of your sliced up shape with total area percentages. Kids can retry and return endlessly to reach five-star precision.

Is it any good?

SLICE IT! is a puzzle game that requires an incredible amount of precision and specificity. When you're slicing a square or circle into even pieces, you probably won't break a sweat. But before too long, you'll be asked to divide completely irregular silhouettes (like a soda cup with a straw) into 12 even segments. It's definitely tough. It's also rather habit-forming. And it presents the kind of geeky thrill that will make fans want to jump up and high-five the nearest nerd whenever he or she finally figures out the perfect solution to a puzzle.

Talk to your kids about ...

  • Explain about area, making sure kids understand that (radically) different shapes can have the same area.

  • Take turns on particularly challenging shapes.
