Puzzle Quest: Challenge of the Warlords blends a match 3 game with an old-school fantasy RPG. As you roam the overworld you complete quests, earn gold, gain experience, buy equipment and upgrade your stats just like any role playing game. But when you encounter an enemy a Bejeweled-like tile swapping game appears. Match gems to cause damage and collect mana to cast spells to help you defeat your enemy. It's a remarkably well-balanced game that's as easy to pick-up and play as it is to continue playing for hours upon hours. And it's one of the most addictive games I've played in a very long time.
