Per instructions, word similarities are computed using word vectors[1].

Note that the relatedness of words will depend on the training set. Many of these word2vec-based games uses data that was trained on Google News[2], so if "Unrelated Words" uses the same data, you should be looking for word pairs that are more common in news but perhaps less common in general text.

Semantle[3] is another game based on word vectors. I like "Unrelated Words" better because whereas Semantle requires guessing one fixed target word, which is often very different from its nearest neighbor, this game requires guessing a set of words, the flexibility of which makes it feel less frustrating.
