I have really enjoyed this game. Prizes and coins for winning, along with other opportunities are plentiful and some on a timed schedule. There is no penalty for losing and replaying a level, which I recommend to enhance your skill. I was in the 800s level before I made a small purchase of $2ish, and only then because I became lazy. I became very skilled and have unfortunately beaten all the levels. Hope developers update with new levels soon. Fun, non-timed, skill based game!
