Game details

The game will run for 48 hours: * Start: 2026-03-20 16:00:00 PDT (2026-03-20 23:00:00 UTC) * Stop: 2026-03-22 16:00:00 PDT (2026-03-22 23:00:00 UTC)

Note:

• Teams must have an on-site presence to claim prizes.
• No limit to team sizes. (It'd be unenforceable anyway.)
• Scoring is dynamic, the amount of points the challenge is worth will reduce over time as the challenges get more solves (as a result, your score may go down over time as other solve the same challenges as you)
• Onsite challenges are worth 0 points and will not affect team standings (lockpicking). But you will get cool stickers and candy!
