An excellent game heavily inspired by Puzzles & Dragons
Dungeon Gems is a game which adopts the principle of the internationally successful game Puzzle & Dragons.
This game by Gameloft breaks away from the standard model, offering a mix between match 3 (where you must associate squares of the same color) and role playing where you have to build a team of heroes and adjust the elements you use to counteract those used by your enemies.
Even though it takes a bit of practice to get used to all the little intricacies, Dungeon Gems is a very good game.
