Choose one of 10 separate public walls for your current mark. Your allowance is one contribution across the entire alley—not one per wall.

Take your time. There is no normal drawing timer or creative mark counter. Use sprays, markers, and approved stamps freely, then choose Finish & Review when your unpublished piece is ready.

Your draft autosaves privately in this browser and can be offered for restoration after a refresh. Successful submission or confirmed discard clears that saved draft.

Undo and Clear affect only your unpublished draft. Existing public artwork cannot be erased by regular visitors. After final submission, your mark is public and cannot be edited by you.

The 60-minute cooldown begins only after the server accepts and stores a valid contribution. Discarded or rejected drafts do not start it, and every wall remains viewable while your can cools.

Rule-breaking content may be reported and removed by moderators. Privacy-conscious anonymous cookies and one-way network hashes help enforce limits; raw IP addresses are never displayed publicly.

Multiple visitors can paint the same wall at the same time. Your draft stays separate until submission; if someone publishes first, the latest wall refreshes underneath your safe draft.

Before submission, you always see your mark combined with the latest public wall. Walls are not reserved or locked, and accepted contributions are layered in server order.
