Fun but needs to be faster Beating each others highscores is fun. However, Plz let the number pad respond faster when we click because I really type fast especially when it comes to the easy difficulty.

Challenging The best part of this game is beating you friends scores! I reached 34 in easy mode. One thing I would recommend is to add a feature to see global highscores and submit mine.

Wow Didn't think this mini game will make me spend my time trying to break highscores and challenge myself

Fun Make an option to change the layout of the number pad though.

Addictive Brain Trainer A nice, basic mental maths app with clear icons. I downloaded this to help me to improve my mental maths skills. Putting the date as my name, when I have a highscore, helps me see how I have improved. Very useful little app which I will also download on my tablet! Update - This app works great on my tablet too :) highly recommended.

Not bad Not a bad attempt but no comparison to Math Workout. Also, keeps crashing too often.
