I can't be certain, but the music for Castle V Castle sounds very much like it was made on an old Roland TR-808 drum machine or equivalent plug-in.
Your ears will be familiar with the 808 even if your brain isn't - it's about as ubiquitous in hip hop as the Amen break. That's actually quite fitting, because this minimalist strategy game has the rhythms of a call-and-response rap battle.
That's something you could say for all I-go-you-gos to an extent, but the bellicose back and forth here is especially sizzling, snappy, and scintillating.
You've got three Mates in the Castle (MCs for short): a witch, a knight, and a hard hatted builder. Each generates different resources each turn - magic, weapons, bricks.
The cards in your hands cost resources from one those three categories, and you play or discard one a turn. Your goal is to either smash your opponent's castle to bits or build yours up 25 bricks high.
