What’s It About?
NINEGAPS challenges kids to solve a grid of six equations as fast as they can by dragging numbers to fill empty spaces. Kids must place numbers so each vertical and horizontal equation is correct. Equations include addition, subtraction, multiplication, and division. Five levels accommodate a range of players. When kids complete each equation in the grid, they hear a chime for correct or a horn for incorrect.
Is It Any Good?
NineGaps is a fast-paced, entertaining math game in whch kids try to solve a grid of equations as fast as they can by dragging numbers into gaps. The rules are simple and multiple levels provide different challenges. Kids can try to beat their previous times on each level and improve their arithmetic skills. Other than choosing the playing level, no customization -- such as choosing operations for each puzzle -- is possible.

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.
