I challenged a friend with a verses match in alphabear, but someone else competed as well. How did they do that when I didn't share the link with them?
Anyone can play in any verses match. This is possible due to the "Random Challenge" option. I have confirmed this with Spryfox via email.
Spry Fox Support (Ray), Mar 14, 1:03 PM: Yes, any challenge can be selected at random by the random match option by default.

When asked about switching it off:
Spry Fox Support (Ray), Mar 14, 10:11 PM: Sorry, we don't have that option at this time. However, I can relay it to the dev team as a suggestion!
