Konami has dived head-first into the mobile gaming waters with Chain of Souls, an iOS game that blends elements of the puzzle and card battle genres. Using the touchscreen, players must link together three or more runes of the same color to form a chain and attack their opponent; the more runes you link, the more damaging the attack.

Simple, right? That's where Chain of Souls' cards come into play.

Should you manage to form three or more chains, you can play a card. These cards have a variety of effects, such as reducing the damage you take or increasing the damage you deal. Your cards can also have relationships with other cards in your deck, which can boost their power even further.

The game is free to play, and available now via iTunes. [Image: Konami]
