Investigate making the card look more flippable

Some users don't realise you can click to flip. Maybe raise the card on hover?

I think a better option would be to slightly rotate the card on hover. That is a better hint as to what interaction is actually available - flipping it.

@tom-james-watson A dog-eared corner is also pretty widely understood as a sign of double-sidedness.¹

That could spur people to interact with the cards even after placement, and discover the flip action. Perhaps it could even appear only after it's dropped on the timeline, to be even more noticeable.

Notes

1. (See, e.g. the current Tumblr post design, where they have a dog-eared upper right corner that only appears when you mouse near it. That's actually a holdover from their previous design, where the posts were flippable, and showed stats and links on the back side. That went away with their post-pornpocalypse redesign in 2018. So now the posts are not flippable, the three-dots menu in the upper right corner provides access to the former back-side content, and the dog-ear is somehow both meaningless and redundant. #ClassicTumblr 🙄 )

Having so far only played wikitrivia on my mobile phone, I have to give a +1 to dog-eared corners, as hovering will be difficult.

Maybe the corner could also be animated a little bit before the first ever time that someone flips a card, like a sort of tutorial or invitation to click an already-placed card. Something like this MWE could be nice, however not triggered by hovering but just periodically moving a tiny bit on its own: https://codepen.io/cseeds/pen/rNOBQW
