Just when you thought it was safe to hang up your mathematical hat, along comes Carmen Sandiego to dash it all. Elsewhere we've got some card games on DSiWare — it's been a while — and zombies.

3DS Download Software

Zombie Slayer Diox (UFO Interactive, $5.99) — The latest 3D game from Samurai Sword Destiny publisher UFO, this is about rocking out and killing zombies, something we can all get behind. Our review will ring out across the world in the near future.

WiiWare

Carmen Sandiego Adventures in Math: The Island of Diamonds (The Learning Company, 600pts) — The fifth entry in Carmen Sandiego's globe-trotting problem-solving adventure series, this will be more of the same as its predecessors but hopefully with a little added twist. Our review will formulate equations and combobulate words and a number to represent the game's quality.

DSiWare

1st Class Poker & Blackjack (Cosmigo, 500pts) — Released in Europe last week, our review of Cosmigo's take on these classic casino games will be live in the very near future.

Swapnote users will also get a free message inspired by Nintendo spokesdog Uggie. Really.

That's your lot for this week, folks. What are you getting?
