What some of our customers say:

Every step in keebox green has been created from scratch. We take a lot of pride in designing original challenges, no AI, no copying from other creators.

Open the puzzle box step by step by discovery, logic and applying tools you find along the way. 60 minutes+ playing time that will get beginners hooked and challenge advanced puzzlers. And when you are done it's easily resettable, ready to be solved again.

keebox green delivers on what our brand is best known for: creativity and mechanical ingenuity. Everybody will encounter something she or he has never seen in a puzzle box before, no matter how many you have solved in your life. That’s a promise.

keebox green is small enough to live on a coffee table or desk, but still delivers countless challenges, both big and small. It’s designed to be a conversation piece that people can't keep their eyes and hands off.

Designed primarily for individual puzzlers, keebox green also shines as a cooperative challenge for two. Bounce ideas off each other, test theories, and enjoy the moment when the mechanism finally clicks.

keebox green is our newest puzzle box, but it’s not the only one. The keebox line-up consists of five puzzle boxes, each one a unique challenge on its own.

This campaign features the keebox green as well as curated bundles of the keebox series. You also have the option to add on any keebox to your favorite reward tier.

Each keebox is its own adventure, fully independent of the others. They have different overall difficulties, which affects the estimated solve time per box. Feel free to solve them in any order you like.

Do you want to build your custom bundle? Missing a specific keebox in your collection? Need extras? Every keebox is available as an add on.

keebox stands for playful curiosity and clever design. From the very first idea to the finished product, everything at keebox is created in Bern, Switzerland.

Together we started keebox with no more than heads full of ideas and the urge to create. Step by step we were able to grow organically without any external investments. Every penny we made went right back into building our infrastructure, optimizing processes and growing our brand. We are proud of what we have achieved so far, together with an amazing community of puzzle enthusiasts around the world.

Each keebox is assembled in collaboration with our valued local partner institutions, firstep and Port 34. We are proud to work alongside these organizations and are committed to building long-term, meaningful partnerships that support their programs and the communities they serve.

firstep

firstep represents the first step toward vocational integration. The program is designed to help clients reacclimate to the work environment and build resilience in order to achieve sustainable and effective vocational integration. To tailor the rehabilitation process to each individual’s needs, adjustments to both the content and structure of the program are always possible.

Port 34

The program is aimed at 15 to 25 year olds who do not have an apprenticeship. During so-called “motivation semesters”, they participate in hands-on work assignments, receive academic instruction, and benefit from daily coaching to help them transition into a vocational apprenticeship.

Every keebox is produced in-house in Bern, Switzerland. We operate our own 3D-printing farm with more than 20 machines and have years of experience producing high-quality puzzle boxes using FDM 3D printing.

Each keebox is printed from durable PLA+ filament, with every part carefully produced and checked to meet our high quality standards. For selected mechanisms, we use metal springs to provide additional durability and ensure reliable operation over time.

For the launch of keebox green, we’ve expanded our production capabilities with six additional machines, giving us the capacity and flexibility to handle even high demand while keeping production on schedule.

This project is promoted by Jellop, the ad tech power behind the best Kickstarters with 3,500+ successful Kickstarter projects with over $1B raised between them.
