Plunk! The marble maze game by Ontario Microbrewed Games Inc. is a brain-teasing puzzle game that will put your skills to the test. Inspired by handcrafted puzzles, each level challenges you to navigate gorgeous marbles through a wooden labyrinth.

Using your iPhone or iPad, tilt your device in all directions and use gravity to roll the marbles past holes and into their targets. The game starts off with simple levels that test your hand-eye coordination as you maneuver one marble around, between, and sometimes over fiendishly placed holes.

As you progress, the difficulty escalates with the introduction of multiple marbles. You'll need to come up with increasingly complex plans to successfully guide two, three, four, or more marbles simultaneously.

Plunk! is a free game that offers 12 levels and is supported by ads. If you want to enjoy more levels and remove all advertisements, there is an optional upgrade available within the application. Challenge yourself with Plunk! and see if you can conquer all the levels!
