App Description

Number Stax is a puzzle game to test your number skills!
Drop numbers and operators in the correct places to match the number or expression shown at the top of the screen to score. You can’t remove tiles but you can swap them around. You can freeze the game at any time, but remember to watch the clock! Eliminate tiles, score points, and earn bonuses and achievements for as long as possible until your grid is full! Remember, the longer you play the faster it gets. Share with your family and friends to see who can get the highest score.
Designed for ages 12-18 and adults too
