I listed some decent Android games I know of in a past thread.

The real secret is to look for board game adaptations and stuff you’d normally find on Steam.

I also have expanded my list for when I have the Play credit and desire for more mobile games:

• Golf Peaks, Pup Champs, and Railbound — more puzzle games by Afterburn, the same developers as inbento
• Digital board game adaptations by Dire Wolf Digital, like Root, Everdell, Clank!, and the Fox in the Forest
• Coromon and Cassette Beasts for your creature-collecting needs
