I got 97/100 (80.5k) by picking the answer that has no relation to the word. Most of the incorrect answers bore some relation to the word, whether that be phonetic or a similarity to a root word.
Yeah I got 75k~ and did something similar ... most of the expert and grandmaster ones had at least 1 or 2 obvious incorrect answers, then it was a 50/50 so I usually went for the thing that sounded either closer to the root of the word or completely left-field
Anything up to expert was obvious
