Take one part Faerie Solitaire and two parts Puzzle Quest and mix in a little Poker or Yahtzee for good measure and you will get something like Runespell: Overture.
You're a changeling of some sort and you fight monsters and take quests in exchange for coin and buffs (which come in the form of power-up cards). There's a story but it's not the strongest element in the game. Like the Puzzle Quest games, your battles are determined by playing a mini-game. Instead of match-3 though, the game is a card game similar to poker in which making certain combinations of cards (pairs, 5 of a kind, full house, flush, straight) will do a certain amount of damage to your opponent, who is trying to do the same to you. The ability to steal some cards from your opponent, plus the limited number of moves you get per turn to move cards or play power-ups adds just enough strategy to the game to keep it interesting.
Admittedly, the game can get a bit repetitive after a while and I found the dialogue options to be a bit tedious but fortunately the game allows you to skip them if you want. It's an easy game to learn, and it's an entertaining casual game to play. It seems to be pretty short and the achievements don't seem too difficult to collect if that's your thing.
Finding little gems like this is the reason I buy bundles.
