Tetris-clone Block Factory arrives on the 3DS eShop this week. It costs £3.60.
Block Factory, developed by Pyramids studio Enjoy Gaming, focuses on the ability to customise games with your own puzzle shapes and themes, which can then be shared via QR codes or StreetPass.
Pricey DSiWare picture and video studio Inchworm Animation is also set to launch. It allows you to create stop-motion videos and time-lapse photos with a range of other graphical tools and painbrushes, then export them as GIFs or BMPs. It costs £7.20 or 800 DSi Points.
Finally, 2 Fast 4 Gnomz arrives on the Wii Shop Channel for 500 Wii Points (£3.50). "Join Bumb, Berzerk, Speedster and Uncle Time as they embark on their mysterious quest," Nintendo explains. "Along the way, take the chance to run faster than a speeding rabbit and more powerful than a raging elephant!"
