Please note, that the resolution of the screen should be corresponding with the size of the screen. If you have a big screen, but low resolution, you'll see only a part of a puzzle at a time if you choose more pieces. This may happen with Verizon Ellipsis and some LG tablets.
If you choose higher levels of difficulty on phablets/phones, you need to complete a puzzles fragment by fragment. The whole puzzle is divided into parts and you see only 1 part of a puzzle at a time on your screen. When you finish one part, you'll automatically get to the next one.
Complete all parts to see the whole puzzle!
