Nintendo-created puzzler SpeedThru: Potzol's Puzzle will be released on the 3DS eShop this week.
It's an Aztec-themed brainteaser that involves rotating 3D objects to fit them, key-like, into the correct slots. It's a bit like Hole in the Wall, but without Dale Winton.
SpeedThru's Nintendo-developed pedigree comes at a price, however: Ł5.60/€6. But you get 90 stages for your money, plus local two-player using one or two 3DS systems.
A free demo of Farming Simulator 2012 3D is also available. It allows you to drive a fleet of authentic farm machines from renowned manufacturers around your fields, plus explore nearby roads, a small village and your house. Presumably not in a tractor.
Also on the eShop: Pirates Assault, a tower defense title released on DSiWare for Ł1.80/€2.
And on Wii there's Violin Paradise, which allows you to shake your Wii Remote and pretend you're a master violin player for 500 Wii Points (Ł3.50).
