This achievement speaks for itself. You will get it in the natural progression of the game if you are trying to get 1k (that is if you play the majority of it alone anyway).
If you just want this achievement, the fastest way to get it is to play 10 challenges (any of them) on Easy. Let the AI guess first. They will almost always guess wrong. Then you also guess wrong or let the timer run out. This will end the Round. Do this until Round 4 and make sure you take the Round. Use the website below to get the answers right everytime.
