Frequently Asked Questions

Do I need to know how to code?

The puzzles reward technical reasoning — basic programming concepts, cryptography, network inspection, and data formats. You don't need to know everything upfront, but writing small scripts or using analytical tools will help.

How long does it take to complete?

Average completion time for developers is between 1.5 to 2.5 hours. You can complete the chain in one sitting or pause and return whenever you like.

Is there a time limit?

Your game session token retains your level progress for 30 days from creation, giving you plenty of time to solve at your own pace.

What is included with the launch offer?

One checkout grants full access to the complete puzzle chain sequence. Currently free during our launch month ($10.00 USD standard price after launch). One-time payment with instant email delivery and no subscription.
