Math CAN be fun!


I found this game on AppGratis and at first wasn't interested in downloading a math game. However I read the description and decided to give it a try. The goal of the game is to try and reach a target number in 9 turns or less. This game is actually really addicting and educational at the same time. Whether you're in elementary school or an adult, this game will improve your math skills in a fun way. Nice job Daniel Sadjadian! This app deserves 5 stars for getting a non-math person like myself interested in an educational game.

Spectacular Challenge!


I'd certainly change my rating if there was a way in the settings to control which operations could be used. Or at least input a limit on the "Target Number." I'm a teacher and would love to use this in my classroom but feel my students would be overwhelmed and would quit when the Target Number gets higher so quickly.

Learning made fun


Brain training is one of the most crucial activities needed in our lives. Try this and have fun
