I went through the entire chat, but unfortunately it appears nobody guessed today's genre Instructionless correctly, so there will be no bonus otters handed out today. Better luck next time.

... What's that? Wrong event? ... Never mind me then.

Hint: ⚠️ See if you can figure out the how the small circles and large circles might be related to each other. ⚠️

Full rules:

⚠️⚠️ Divide the grid into rectangular regions. Each region must contain exactly one circle. Borders with black dots separate two regions with black circles in them. Borders with white dots separate two regions with white circles in them. Borders with grey dots separate a region with a black circle in it and a region with a white circle in it. ⚠️⚠️
