Hello There, I do indeed like puzzle and have since been downloaded some apps on my tablet. Ravensburger has a good name and is certainly not bad. Companies also have costs, etc, and can not give away everything, alright. What I but very negatively assessed in this app is that you can just get by 6 puzzles for after all but 2.99 euros, from there have to buy one. That's very little. So 10 or 15 (as minimum at the other apps) hättens may be. I will not recommend this app.
