If you want to have fun playing this game for free don't bother. You need to watch so many adds so that you have gems, energy and more to actually play and merge items (which is the fun part). Really tried but just got so bored having to watch ads every 2 seconds so that the elves woke up or for energy so that I could play the level stages. And that took the longest since you only get 1 energy per add.....
