After a few weeks' wait from its European release, the 3DS eShop in North America gets a piece of portable pinball, with DSi owners getting some balls and bumper action too. Elsewhere there's a little music and some more maths.

Zen Pinball 3D (Zen Studios, $6.99) — An excellent pinball title in its own right, Zen Studios plans to support this game with extra downloadable tables in the future too, so it's a sound investment. Here's our Zen Pinball 3D review for you to mull over.

DSiWare

Hip Hop King: Rytmik Edition (Cinemax, 800pts) — The hip hop music creation studio finally reaches North America after nearly a year's wait and it still sounds good after all this time. Check out our Hip Hop King: Rytmik Edition review for more.

101 Pinball World (Selectsoft, 500pts) — Teyon and Selectsoft's penchant for cramming 101 things into one game extends to pinball now. It's unlikely 3DS owners will buy this instead of Zen Pinball 3D, but we'll review it anyway to see how the two stack up.

WiiWare

Carmen Sandiego Adventures in Math: The Case of the Crumbling Cathedral (The Learning Company, 600pts) — Another instalment in the maths-and-masonry series, this likely won't change anything from the previous outings but our review will see how it adds up.

Nintendo Video

Kirby: Right Back At Ya! Volume 1 (available 14th January at 3 p.m. PT) — Kirby's ready for action in part one of this special, two-part 3D episode of Kirby: Right Back At Ya!

That's all, folks. What are you getting this week?
