By BPlus Games, a new eShop title was announced in which you hold the 3DS upside down to play. Yes, upside down.
You essentially use the top screen, which is in this case the touch screen, to drop blocks down to the bottom screen to fill up a bottle in a unique puzzle game.
The game is coming on December 25h 2014 to Europe and this holiday season to America’s eShop for Nintendo 3DS for USD/CAD/EUR 2.99
You can check out its official website
