I kind of take back what I said... Here's the run for people who didn't experience:
-Around 9AM UK time, Nike posted an image with 8 hints (the 8 shoes that were restocking).
-Within the SNKRS app, people had to find out how to unlock these 8 shoes.
-This invovled going to a related page of the show you believe the clue was for, looking at the images, noticing differences and then using ur finger to shade in these differences or change the shoe to another colour.
-Example 1: Find "Behind the design page" for SW 97/1, scroll the images, notice the insole smiley is upside/not shaded in -> use finger to shade in. Unlocks ability to purchase SW
-Example 2: Go to design page page for the All white "Off-White" Jordan 1s -> see image of the shoe, shade it in with finger -> image turns UNC blue -> unlocks ability to purchase OW Jordan 1 UNC
-Example 3: Go to "For the love of Nike Air max 95s page" -> image of some air max 95 colourway -> rub finger across it (like a scratchcard) and it'll change to the Atmos 95s -> unlocks ability to purchase Atmos 95s.
All in all, I felt this was the best way to beat bots, and pretty inventive - no one expected it. Not sure how they could've made it fairer.
