5 stars: Several different games, all entertaining. You can easily avoid ads by playing offline. Even if you play online, the ads are short and change often, so they don't bore so much. Only thing: I wish I could change the language (I'm playing the Spanish version and it's Spanish from Spain, many words aren't used in Latin Spanish).
5 stars: Good mental and visual stimulation
4 stars: Good way to learn words for my kid
4 stars: I like the game a lot but I do not want to sign in to facebook....and is that the reason I cannot get the app?
3 stars: very good, the only bad thing are so many commercials of up to 30 seconds ...
2 stars: Very entertaining, but too many ads. God!!!
