SPARROWS Challenge Vault Instructions (PDF)
This is more than a puzzle box … this is safe cracking.
Get ready to learn a new skill with this challenge. The Vault is a professional three wheel lock and safe dial that is mounted onto a desk top presentation case. Spin the dial, listen and feel the clicks of the wheels as you manipulate the Vault open. Once completed for the first time the vault will open to reveal a collection of tools and parts that will allow you to alter the safe into a progressively harder challenge. It also includes a special key for changing the combination. The Vault is much more than a onetime puzzle.
