If you're having trouble reading the definitions clearly, please know that you can zoom in and out the grid. This feature is designed to offer you a better view of the grid and improve your reading comfort. To zoom in and out, simply use your two fingers, as you would normally do on a touchscreen.

Even after zooming in, you will be able to navigate through the grid in the usual way, allowing you to continue playing comfortably, regardless of the displayed size.
