Nice game. Makes you think. Needs an 'undo' button. Currently need to do all the math in your head before you start. Allows for no experimentation.

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.

Finally a math game with simplicity at the heart. Great design and fun!

Just needs a way to leave the game without having to play through. Just add a menu button.

This app is more frustrating than enjoyment....when you get into the larger numbers too difficult to figure out with the remaking moves

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.

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

Needs an undo button and ability to write math operations. Like a more advanced calculator it would be good to be able to see what you are inputting before having to commit to the turn.

Warning: This app makes loud sounds that are implemented as alarms, and so are not affected by the device's normal volume controls. This bad practice automatically gets my lowest rating (and removal of the app from my devices).
