thank you for making this! could you please add shorthands as acceptable answers (e.g. just "chilean" should work for the Chilean Sea)

Level 62

Oct 18, 2023

Yep! It seems I forgot to make the sea for Chilean Sea optional, but all of the other type-ins should be fine.

Also, it looks like the svg shape for the Mar de Grau isn't working

Fixed!

thank you for your quick patches! one more note, it seems that the sea of chiloe and parry channel are missing SVGs

Level 62

Oct 19, 2023

Thanks for all of these suggestions! The Parry Channel and Sea of Chiloe were two last minute additions, so I guess I just forgot to add them

Awesome quiz! What might be handy is a 'seas missing' button, since a lot of them are quite small.

OMG!!! I can’t wait to take this quiz. From the questions I read above it seems like there might be different answers that are acceptable for some of the smaller sounds, channels, and straits?

Kudos to the creator of this quiz, Jacoba! This is really great.

Absolutely love this quiz! Almost at 100% from memory hehe

Couple notes here:

- Sea of Alands doesn't fill in green when entered

- Both "Viscount Melville Sound" and "Weddell Sea" don't appear on the SVG (at least, not that I could see. With only those two left and giving up with 5 minutes on the clock, I could not see a single red dot on it)

Other than that, I'm definitely using this quiz to help memorize all those trickier gulfs and bay
