Frostfire

From the maker of the superb roguelike Pixel Dungeon, Frostfire is a simple and satisfying match-3 style puzzle game based on a hexagonal grid. As you would expect from developer Oleg Dolya (watabou), the design is elegant and simple. The music is a very nice complement to the gameplay and visual design. It’s a worthwhile time-waster, fun for children and adults.

If you’re going to play a puzzle game in this genre, you may as well make it this one — pay what you want to an indie developer, and enjoy a pure game with no ads.

Currently it’s $1.99 on Google Play, $0.99 on iOS, or pay what you want direct from watabou for Android, Windows or Mac.
