Scritchy Scratchy Challenges Guide
Challenges unlock after your first Prestige. Two appear at first, and more open as you clear them, up to nine. Each is a separate run with its own rule, dollar target and reward. Clearing all nine unlocks the secret catalogue with three tickets. Three achievements track one, five and all nine challenges cleared.
Names and rules come from the official Challenge Update notes and the itch.io devlog. Rewards, difficulty order and troubleshooting for a missing challenge are not documented in the sources read.

How the nine unlock
After the first Prestige, the Challenges tab appears with two available runs. Clearing them opens more until all nine are listed.
Each challenge starts a fresh run with its own rule. Normal progress is not the point; the goal is the challenge dollar target.
