Frog Su Doku app for free

The mck

This is a good app with a full 9 x 9 grid and it takes up a small memory space. Has a features that allow you to enter a number as many times as you like plus it indicates where selected number is elsewhere on grid etc. (Adverts at the bottom of screen are not too intrusive). Just a pity it does not have medium or hard as a free option but adverts & pay for upgrade makes them money so not surprising, D

Too easy!


Everything about this app is good apart from the fact there are only easy levels. Bring in some other options and this would be 4 or 5 stars.

Developer Response

Thanks for taking the time to share your feedback. We've taken it on board and recently added another difficulty level as well as Daily Challenges of a wide range of difficulty (Easy Mondays, Medium Tuesdays&Wednesdays, Difficult Thursdays&Fridays, hard Saturdays, and Evil Sundays).

Nice easy app


Didn't know I would like a game like this ... now I have been playing for 2 hours... waiting for iPad battery to die so I can take a break :)
