I have a lot of fun with this; however, several bugs have been occurring frequently:
When I play using quadrants and complete a section, the game is supposed to shunt over to the next section - except it doesn’t always. The only way around this has been to “sweep” the board (even though all pieces are together in their proper places). Sweeping then removes several pieces out of the puzzle that you then have to put back in. Sometimes this doesn’t work, though. The only other solution is to exit the game, sit through another ad, go back to the puzzle, and try again. This also doesn’t always work. Sometimes I just have to not play for a few days until it begins working properly again.
A similar issue happens with completed puzzles. I will complete it, go into “My Puzzles,” and see it in there with only a percentage completed. Sometimes when I go back into it, there are no pieces to add in and the puzzle just sits there incomplete. Sometimes I can sweep out pieces and put them back in, but it still doesn’t get marked complete and I can’t do anything with it.
These aren’t game-breaking issues, but they are annoying.
