Tesla Box (Puzzle Potato)

A tribute to Nikola Tesla and his lost invention — and the one box in this collection that runs on more than just wood. Inspired by the sketches and schematics from Tesla's own laboratory, this puzzle blends mechanical and electronic challenges: charge it up until it glows green, crack the electronic lock, then work the acrylic sliders and hidden mechanisms in sequence to reach the secret at its core. No batteries — it draws on electromagnetic power, exactly as Tesla would have wanted. An expert-level adventure that makes you feel like an inventor uncovering secrets hidden in time.
