The day is finally here: issue 11 is out now! To help you celebrate launch day in style, we’ve set a puzzle hunt: throughout the day, we are posting a series of puzzles. The answers to these puzzles form clues to the four-digit code for the door to let you into the Chalkdust issue 11 secret backstage lounge.
There are five puzzles in the puzzle hunt. They are being posted every 2 hours: at 9am, 11am, 1pm, 3pm and 5pm.
