When I first started playing this, I figured it would be like most of the other games I’ve played on here… download it, play a few times, get bored, then delete it. But for some reason, it held my interest, and I kept coming back to it. There have been times when I would play for a couple of hours. Also, it IS possible to play without spending any money, once you figure out the strategy to get the higher numbers more quickly (without cheats). I finally completed it today, because after 999, there are no more numbers. I’m disappointed, because I wasn’t ready to stop. Hopefully, they’ll update it in the near future, and add more numbers.
