A Lot or a Little?
What you will—and won't—find in this app.
Kids can learn how to build equations using given numbers while strategizing to eliminate as many of the numbered blocks per round as possible. The game begins with simple addition and increases in difficulty as kids progress into multiplication. The game offers little in the way of instruction or hints so if kids get stuck, they might resort to using random equations just to earn stars, rather than use math skills to complete the puzzles. While The Unknown Number is an attractive math puzzler, kids might need more help than what's on offer.
Ease of Play
Content is neatly organized and the equations are easy to create by tapping or swiping. Instructions are sporadic and brief, and there are no hints when kids get stuck.

Parents Need to Know
Is It Any Good?
Kids will have fun completing the puzzles, but they won't get much instructional guidance, so concrete learning could take a back seat. For example, it might be hard for kids to progress from simple addition equations to more complex, multi-operational equations with negative numbers. Also, the logistics of the game change slightly with each level; reminding players of the basic strategy through a help button might ease possible frustration.The game could be greatly improved by adding some detailed instructional screens before each new level and hints that are accessible while kids play.
Did we miss something on diversity?
Research shows a connection between kids' healthy self-esteem and positive portrayals in media. That's why we've added a new "Diverse Representations" section to our reviews that will be rolling out on an ongoing basis. You can help us help kids by suggesting a diversity update.
