Update: 3rd time now that all progress has been deleted. Hours and hours of gameplay and unlocking things just...gone. Beyond upset. 😫 OG review: We paid to remove ads & it's great. Lots of replayability. Minigames and Endless are lots of fun and challenging. ZenGarden is great to build up coins to "buy" the additional minigames etc. I play w my son and he absolutely loves it. We have unlocked everything and never had to pay for anything other than that initial few dollars to remove ads.
