The screen keeps going white & freezing

The screen keeps getting stuck and going white

Response from developer

This is not an issue we would expect to occur. It could be a phone/memory issue. Please update to the latest version of the app.

Great app!

Great brain exercise and good way to pass time! The only thing that (somewhat) interferes with my ability to find the number I’m looking for is when the red numbers are all over the grid. That forces me to look very carefully.

Glitches

Very much enjoy this game; the setup is basic but functional. Since purchasing the app, I’ve found there are a lot of times where the game will freeze - most often after finishing a grid and attempting to go back to the home screen the screen will go white and freeze, requiring the app to be closed then reopened. This occasionally happens during playing of a grid as well. It is annoying, but as the app is inexpensive it is somewhat tolerable. Hopefully the creators will help to fix this issue in future updates!

We don’t experience that issue. Can you provide more information please. Have any problems persisted after you updated to the latest version?

Cool game

I recommend this game. It looks like they’ve fixed the bugs and made some improvements.

Response from developer

Thank you for the review. Please update to Version 2.0. We added new functionality in Version 1.7 … and then experienced new bugs (including crashes on certain iPhones models - which we never before encountered). We apologize to you and other loyal users for the temporary difficulties. Version 2.0 has fixed the bugs - and has added features that enhance the grid game (including more convenient replay and a post to leaderboard feature).

Very great app!

This game is an very helpful brain exercise, that helps you focus and concentrate. It can be used for personal use, or for sports. I love to use this before games to get in an focused mindset.

Fun App

Good brain exercise!
