If you gave up at 50, that means you skipped the difficult words.

True. I tried a few more times. There is just so much wrong with the design. First 90 words super easy and then super hard? Why not random? Why is the longest description the correct one? Why so many? Why 3 clicks?

Agree. Complexity for me skyrocketed towards the end

Yes - a very marked step rather than a gradual increase, I thought.
