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

Educational Value

Kids can learn critical-thinking and problem-solving skills as they figure out how to turn small gears to make a large gear turn to unlock keys and prizes. The puzzlers are based on integer partition and help kids build critical-thinking skills as they try to figure out what combination of integers will rotate the large gear to unlock the keys. Research supports its learning potential.

Ease of Play

There aren't any detailed instructions, but tapping a question-mark icon produces a pop-up screen that gives a brief overview of gameplay.

What parents need to know

Parents need to know that Wuzzit Trouble is a math game based on the concept of integer partition -- the expressions of a whole number as the sum of other whole numbers. Kids have to set adorable creatures called Wuzzits free from traps by collecting keys to unlock the traps. Kids collect the keys by figuring out how many times to turn gears and which way to turn them. Points are given for the least amount of turns, and kids can earn prizes and treats for the Wuzzits as they play.

What's it about?

The home screen is pretty simple, with three options: play, change settings, or view a list of trophies earned. In play mode, there are three main levels, with 25 puzzles in each for a total of 75. At the most basic level, kids get one large gear and one small gear. By turning the small gear one time in the right direction, the large gear turns to unlock a key. Each turn of the small gear moves the large gear five places. On more advanced levels, kids have to manipulate several small gears to move the large gear and unlock multiple keys and food for the Wuzzits. Kids earn more points and star rewards for fewer moves. By tapping on the settings icon on the home screen, kids can turn music and sound on or off, access information about the developer, or reset the game. Also, by tapping on the trophy icon, kids can look at the trophies they've won.

Is it any good?

WUZZIT TROUBLE promotes learning through engaging, challenging gameplay. Kids will enjoy setting the adorable Wuzzits free from their traps while playing a game that builds critical-thinking and problem-solving skills. The puzzles get increasingly difficult as kids make progress and unlock levels. So, while using the game is straightforward and intuitive, adding some hints for higher levels would help kids who struggle. Fortunately, there is an option to redo each puzzle, which encourages kids to keep trying -- and trial and error is an excellent way to teach kids how to problem solve.
