Semantle is weird. Words you would expect to be close are not. For example: castle is far from moat and stone. Why?
I think the way the similarity is done is based on word co-occurrence and the dataset used is news articles. So you can imagine that not a lot of news articles mention castle in that context.
Then you have cases that drive me crazy, like the guess "food" is very far from the secret word "cupcake", and "toy" is actually very close to "cupcake". What?
Like, come on. This is not playable or fun.
For reference, these are the words close to "cupcake",
