Once in the higher level (400+) the games are increasingly difficult to win and take too many attempts. Fortune Path was a partial fox, originally incremental amounts per milestone, now a flat 20 each milestone, not enough to keep pace with difficulty at 900+ lv The newest issue is ADVERTISEMENTS are initiating during game play or after starting a new puzzle, not just in-between puzzles. That is an unacceptable, especially on daily puzzles that are times. Other issue is when ads crash the app.
