So far great game. Absolutely LOVE no ads. I'm currently at level 104 (which doesn't take forever with no ads), and the game keeps getting more interesting and challenging. I saw a review indicating the need to purchase "helps" further down the road it as it becomes so difficult to beat higher levels without spending money. I haven't experienced that, but again I'm only at level 104. The rewards are pretty good and I usually save the "helps" for the more difficult levels. I love a good challenge, but I really don't like to spend money to get past levels. Not that I've never spent money in these games, but the special little $2.99s here and there add up. I'm usually patient enough to try as many times, with as many different strategies needed to beat a level. If I do get frustrated, I walk away for a bit (sometimes days), or play something else. Overall, I really like this game. Graphics are great, and did I mention NO ADs?! Lol. I frequently install and try games that spark my interest. I'm pretty picky; some games don't make it an hour or a day on my device before being uninstalled. So, we'll see how long it lasts. Angry birds and CandyCrush are still on my device. I don't play them as often as I used to, but they're still in the rotation, and I go through phases with games. However, they are "classic" GO TOs to me and have never been uninstalled.
