Princess Nuriko - A logic puzzle of a slightly different kind, Princess Nuriko is an Android re-imagining of the pencil and paper game nurikabe. Your goal is to fill in the "islands" surrounding each number and mark off non-filled spaces. Instead of just blocking off sections of the grid, however, you're partitioning farmland for the people of your kingdom, which is an interesting sort of story to tack on to the logic puzzle solving. Plot or no, the game plays smoothly and looks great. The 3D mode is nice to look at and shows you forests and farmlands as they grow from your completed puzzle. More levels would have been a good thing, but the few dozen that are here will provide a satisfying amount of challenge. A free Princess Nuriko Demo is also available.
Picma Squared - From Moonberry Studios, the folks who crafted the original picross-themed Picma, comes another logic puzzle game that's nothing but wonderful to play. Similar to Princess Nuriko above, your goal is to use number clues to fill in islands of blocks surrounding numbers. The difference here is each number represents the number of blocks that touch the number square, not the number of spaces to fill in. Even though the concepts are similar, the strategies you'll use are vastly different. Plenty of puzzles to complete, an interface that works well, even on the small mobile screen. Picma Squared Free is also available.
Crush the Castle - Ok, we couldn't supply you with a pure stock of logic puzzles. Well, we could, but sometimes you just gotta break down and wheel out the trebuchet. Crush the Castle is the Crush the Castle you'll remember from your browser window since 2009. It's the original Angry Birds, and it's got all the physics-flinging action you could possibly want. Pull back on the trebuchet and let the stones fly. Knock down the castle and ping all the people on the noggin to progress to the next level. It's that simple, and it's that engaging. A great port of the must-play browser game. Just as addicting as before!
