If you like Soduko & Minesweeper then you'll probably like Princess Nuriko. The goal is to build farms on a grid with the appropriate forests between them, because good forests (not walls) make good neighbors. What is neat about this game is that it is deceptively simple but can entertain for hours.
It takes a couple minutes to figure out what is going on in this app. The tutorial is translated poorly (ahem, Google translate) which makes it confusing. Just remember 2 important rules: No 2x2 forests and all forests connect. Also go into settings and change the hint setting to the end of the game because it interrupts gameplay and gets annoying.
