The parents' guide to what's in this app.
What parents need to know
Parents need to know that NineGaps is an educational game that allows kids to practice arithmetic in a race against time. Kids drag digits 1 through 9 to empty slots in the equations, using each number only once. Numbers must be placed so the vertical and horizontal equations are all correct. Five challenge levels allow kids at multiple ability levels to play. Addition, subtraction, and multiplication are included in each level; division also appears in some levels. When numbers for one equation are placed so the equation is true, chimes play. Trumpets play when an equation is incorrect. To swap numbers, drag one number on top of another, and they'll trade places. The game's high score list shows the fastest time for each level.

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.
