Time for an upgrade...


I am new to this app and realize how long it’s been out there.

4 Star is a high rating though I am writing in hope for improvement as this app seems to be a jewel with tarnished/outdated interface plus other limitations to attract a new gamer.

The interface doesn’t seem to be designed for the touch screen era.

I want to swipe, not click & select...That’s not even an option any more...

Also the squares are so tiny, with the chunky control area at the bottom, bit waste, though I can seem there is not much room to widen the board due to the information display on the edges. I wonder if this is best for an iPad app instead of iPhone...

The game itself is amazing with such abundant selection and broad/fun themes.

Also not satisfied with limited sizes of boards at lower end. Most people may not be ready to jump into 15-20 after only playing a few 5x5 games. This seems to be designed for hard core fans, though to expand its audience, more in between levels would have general appeal. I came to this game after samples a few at other brain training apps, though I would love to have an app dedicated to this game as it’s very entertaining and addictive. Though I want to gradually get there, 6x6, 7x7...etc would help me practice.

I wonder if there is a chance to do some major overhaul so that it can be enjoyed more.

Love game, hate freezes


I love this game and used to play it daily. It now freezes any time I switch back into the game, blanks and freezes after each level, and occasionally just freezes for a reason I have yet to determine. I don’t know what is causing this, but PLEASE fix the freeze issue. I love everything else about this game and want to go back to daily play, without the frustration.

Still freezing with update


Please try fixing the freezing problem again. It is still freezing even with updating latest bug fix.
