We launched a playable archive of our past challenges!
Isn’t it wasteful that challenges get lost after each game? In these crazy times we wanted some preservation, and to create a way to play and practice with ease for everyhacker.
We even started providing hints and videos for some of our old challenges, and we accept suggestions for them too.
The archive is now itself archived so you cannot spin up VMs and use our servers to play. Nonetheless, the archive’s archive still offers most OOO challenges and instructions on how to safely try out each challenge on your laptop.
