It seems you do need Snapchat to view their snaps. I can't see any other way to access Snapchat online. They don't even seem to have a web interface if you do have a snapchat account. It's all app-only.
The reply from them on Messenger only says to add them so you can see the winner reveals on the 10th with no other interaction required. Best case scenario someone could possibly post a screenshot of the winner reveals on here?
Agreed it is a very odd way to run the comp…
"We'll be announcing the winners on Snapchat (August 10th) 👻 so make sure you add us.

Anyone know if you actually need Snapchat for these things? I've never installed it or used it and have no desire to. This comp requires you to install Messenger and interact with them through that and then tells you to install/interact with them on Snapchat too which is kinda frustrating. Im hoping they communicate with the winners some other way than just the snapchat method!
