The game itself is relaxing. But there are WAY too many ads. Your game gets stopped literally every 20-30 seconds by an ad that was longer then your play time. I understand the purpose of ads because it makes the game free, but I shouldn't have more ad time than game time. There's a no ad purchase option for $11, but the game is nothing special. There are hundreds very similar to it that don't bombard you with ads. Not worth it.
