The beloved Castlevania: Symphony of the Night has undergone a dark metamorphosis into an iPhone puzzle game. Castlevania Puzzle: Encore of the Night is sort of a Castlevania version of Puzzle Quest, with a bit of Super Puzzle Fighter II Turbo mixed in.

Alucard fights his way through Dracula's castle as before -- but now defeats enemies in a match-three falling block puzzle game. You can upgrade Alucard's weapons and equipment to change his stats in the puzzle game -- for example, IGN notes that a new sword could increase the damage done to enemies by successful matches.

The unholy blend of Symphony of the Night and addictive puzzle gameplay could very well steal men's souls and make them its slaves. There's no precise release date, but IGN notes it'll be out "very soon."
