This game is funny, and fun, and worth the $3 to get rid of the ads - but after a while, once you achieve maximum accelerator and maximum kick power, the only goal left is to increase your rankings. Unfortunately the rankings appear to be fake, with fake randomly-generated names for ‘other players’ that show different country flags for avatars. There is no way to see an entire list of rankings, all you get is a short list of about 10 ‘players’ near your rank at the end of each round.
My rank started in the 25,000 range. I noticed that the longer you play, the ranking goes up incrementally nearly the same amount every time, and as you get higher up in the ranks, the increase is less each time, and your progress is slower - until I got into the top 100… then suddenly my rank rocketed to the top #1 position within a couple of rounds. I haven’t played in days and I am still ranked #1, but the player names ranked below me constantly change and cycle through random names.
As I said, the game is fun and worth the 5 stars, but don’t think you are playing for any kind of real ranking - as that aspect of the game is bogus.
