Junk & Jolt

Build wild contraptions and guide Jolt home! Experiment with ramps, springs, fans, magnets and portals across 50 playful physics puzzles.

Build it. Bolt it. Send it!

Junk & Jolt is a cheerful physics puzzle game where every solution begins with a pile of parts and a bright idea. Build strange little machines from workshop junk, press GO, and watch Jolt roll, bounce, fly and tumble toward the charging dock.

When a machine fails, adjust it and try again. Your contraption stays in place, so every attempt teaches you something new. There is often more than one way to solve a puzzle.
