Puzzle & Dragons is part match-3 game, and part RPG dungeon crawler. While it won't set the world on fire like, let's say Puzzle Quest, it has a large following, and is carving out its own niche on the App Store.
It is also now the home of the strangest game crossover we've ever laid eyes upon. The characters of the recent console release Batman: Origins have invaded the world of Puzzle & Dragons. This is not the first crossover in the history of Puzzle & Dragons, and if the game continues to be successful it won't be the last, but it's certainly an odd pairing to be sure.
The content is available in an event specific dungeon that launches today on the 30th and lasts until November 12th.
If you're a Puzzle & Dragons fan, enjoy your batman while it lasts.
