Fun. Sadly though it's just another game that wants you to purchase ad free upgrade every month for the rest of your life. Watch an ad for a free reward, you say? Well Goodluck with that since over half the ads "have a problem," forcing the game to reload, no reward. I have not been rewarded about 20 times. 20, 3 part, 1min+, 5 x close out, ad videos, so I'm deleting this game as fun as it is. This game is basically bullying you into buying the add free upgrade. Unplayable as a "Free" game.

This is a phenomenal game, but the frequency and length of ads wrecks the experience. I've played for a few weeks now, but the ads for everything have driven me to stop, which is a shame. After some time, the ads make this game unplayable.

I like this game so much I bought the lifetime VIP pass. Worth it to me. Now I do not have to worry about any ads or other ads. I know that it is a large chunk of change and that for most these mobile games are just something to pass the time but for me I have gotten to the age where I just want to sit and play a game any only have to think about few things and still enjoy it. I think it is really worth it.
