Where can I market an entertainment product?

Hello!

I'm working on a "entertainment product", and I really don't know well how and where to spread the word about it (besides maybe Hacker News and Product Hunt). Most books and articles about this topic only cover serious products. The type of product that solves an actual problem. And that's not the case of most entertainment products.

Just to give some context, my product is a small website where users can post emojis representing movies, and other users can guess which movie the emoijs represent. It's not a paid product of course, and I'm not planning to make any money out of it. It's just something I'm building for fun.

So if any of you has some insight to share about the best way to work with this kind of product I'll be grateful.

Thanks in advance!
