Spellstone is a card-dueling game in the same vein as Hearthstone. In it, you play against the computer using decks of cards with hundreds of different creatures and monsters.
The game system in Spellstone is simpler than in most other games like it. All you have to do is bring out your creatures one by one, paying particular attention to the order in which you do it. You can only play ONE card each turn, and your creatures will always attack what's in front of them.
Between duels, you can choose different missions related to the main adventure in the game. And, of course, you can purchase new cards and add them to your deck. To pay, you can use real money or the coins you win as you play.
Spellstone is an entertaining collectible card game with a very cool cartoon aesthetic. The gameplay might be too simple for some, but it's a good option if you find other card games overwhelming.
