Too small for phone
To the developer, I suggest making the board bigger for phones. There is enough blank space around the board to do this. Making the board (and thus tiles) bigger would make this app playable on a phone. Right now, it’s too small, so I deleted it.
So my recommendation is, if you have an iPad, this app is perfect. If you’re thinking of playing on your phone, however, it will be too small and you’ll need a magnifying glass. Good game otherwise, though, and good price.
Response from developer
Thank you for your feedback! We have an update in our pipeline which will address the size problem, too.
