Bitcoin Puzzle

The Bitcoin Puzzle was first presented as “Box of Sword” at the IPP24 Tokyo puzzle exchange.
Las Vegas Cardestry expert Andrei Jikh asked Oskar for a puzzle that can be used as a container for two decks of cards. Oskar proposed this puzzle and made a big 3D-printed prototype.
Andrei Jikh, together with his business partner Patrick Kun, launched a successful Kickstarter campaign to fun the production of a gorgeous transparent acrylic version.
