Pocket Marble Runs

What it is and what you do with it: design your own domino rally/marble machine toy on the iPad/iPhone or Android.

First design the track by drawing it on the screen. The replace the parts with a variety of mini-machines and contraptions.

Start the machine - the camera will automatically follow the ball (or dominoes).

What we liked: the concept. Great variety of fun and clever 'contraptions'. 3D visuals. Easy to use. The designs can be saved for further editing. Great fun for 'Rube Goldberg Machine' style puzzles.

What we didn't like: contains banner ads.
