Cards and Castles combines turn based strategy and collectible card gameplay. It's free to play, and firmly at the casual end of the spectrum, with cartoon graphics and gameplay anyone can get into with little effort.
Use cards and strategy to destroy your enemies
You can play Cards and Castles online or against the computer in a campaign or single match. The aim is to overcome your enemy and destroy their base. You have a deck of cards, which allows you to make attack units, give you special abilities, and more.
Each card carries a cost, so you have to think carefully which cards to play each turn, as you have limited gold to spend. Do you spend now on weak units, or save gold for more powerful cards later? As the game is played on a board, and each fighting unit has different movement and attacking ranges, you also have to think carefully about position.
Lacking some tutorials
You get additional cards and decks by playing the campaign. The more cards you have, the better chances you have against your opponents. While tactics on the board are certainly important, without good cards to play, you'll soon find yourself overwhelmed. This is especially true if you play un-ranked online games - if your opponent has a stronger deck of cards, all the clever tactics in the world are unlikely to help.
As you unlock new cards, you can build your own decks, which is an important part of the game. Here Cards and Castles would benefit from more guidance. Newcomers might not even realize it's an option, and while it's not too hard to pick up, more guidance would help.
