So, at last, Pottermore has been updated - on Hermione Granger's birthday, no less. I will be bringing a complete walkthrough for the latest parts as soon as I am done with them; however, for now, here is a small guide on the new addition to Sorcerer's Stone. The potions puzzle was an instrumental part of the book - one that got overlooked. I thought it might be too late to include it but apparently, it wasn't.
The puzzle is easy enough; especially if you remember which potions Hermione had picked out originally. However, you can probably figure it out if you think about it. If you don't want to think though, the last picture shows the answer!
