Dungeon Gems, which works on iOS and Android devices, is one of those games that come with the all-too-common “easy to learn, hard to master” disclaimer in their descriptive blurb. This Gameloft title will have you matching Elemental Runes to trigger attacks from your team of heroes. You can choose from up to 220 “powerful RPG heroes” powered by different kinds of Runes, with each of them having their own skills and elemental attacks at their disposal. Sounds like your type of game?
