But, apart from helpful nudges from mates, being a pinball wizard was very much a solo adventure. Portugal's Cristiana Felgueiras has changed that with a two-player pinball project as part of an Inventables monthly challenge.

The build is beautifully low tech, it doesn't even need to be plugged into a wall outlet. Though quite an arsenal of modern tools were used in its construction. The frame is made from MDF, while the obstacles – including cross shapes, doors, blocks, guides, ramps and tunnels – are all produced from plywood, MDF, acrylic and aluminum using an X-Carve 3D carving machine.

The element shapes were created in Adobe Illustrator software and then exported to Inventables' Easel platform, though Felgueiras does say that it's possible to cut the Adobe step and design in Easel.
