Plunk the marble game for iOS

Plunk the marble game lets you work through increasingly difficult levels to hone your skills at guiding marbles through many different mazes. The game starts off easy, but the challenges pile up fast once you start playing with multiple marbles at once. At that point, you're testing your brain as much as your reflexes, and it makes for hours of fun.

This app features an intuitive interface, with a wood grain background reminiscent of the wooden marble mazes the game is based on. To start playing, just tap the play icon in the middle of the screen to go to the first level. When you've successfully completed that, you'll move on to the next, and then the next after that. To play, hold your device level, and tilt it to make the marble roll in the direction you want. The control is very good, and the marble responds just like you expect it to. The graphics are also very nice, with beautiful color designs for the marbles, and rich wood tones for the mazes.

You start out with two levels available that you can use to unlock additional levels without beating the previous one. If you'd like to purchase more, they are available through in-app purchase. You can get one for $0.99, ten for $4.99, and 30 for $9.99. There is also an option to upgrade for $1.99 which makes more levels available and gives you five more bonus options for free. This app is a lot of fun, whether you're familiar with this type of game or not.
