playables

Yesterday I stumbled across this seemingly new thing on YouTube called playables.
To me, it looks like some hub of random designed mini games to kill time. I don't really know if any of them are accessible at all, on first glance it didn't look like it though.
Anyone else tried?

i've heard of them, but always dismissed the banner describing them out of a desire not to see them. If I had to guess, however, I'd not be surprised if they weren't accessible.

I haven't played them, but I'd imagine they aren't accessible

Where can I find them?
