If you're up for a simple but entertaining puzzle game, check out Naboki. Your objective is to free all the tiles by clicking the arrow on each one. Can't find it? Good thing it's in 3D; players can rotate the figure until they find a solution.
A few features make this game quite clever. Some tiles have more than one arrow, each of which points in a different direction. Combined with the ability to rotate in 3D, some levels feature multiple ways to solve the puzzle. However, watch out for puzzles featuring multiple layers of tiles, since sometimes it is not incredibly apparent. As the levels progress, other features are added to the tiles, presenting new challenges to keep things fresh.
In addition, Naboki features an intelligent design. As soon as the arrow is visible to the player, it becomes a viable and clickable option; there's little fidgeting and manipulation of angles to get the puzzle to work. It also features solid physics and satisfying, realistic shadowing and textures.
Give Naboki a try!
