It all comes down to luck and speed really. You just really want to hope you get enough questions you know the answers to.
UPDATE: One minute on the timer should be about halfway on the circle/timer at the top. (So about 2 minutes on the timer when you start). Completing a question adds more time to the clock and that's the key here. Be quick to answer the questions to add time. You can skip, use hints and Oust and it still adds time once the question is completed or skipped.
Also, even though I don't mind the negative feedback as long as it's helping someone, please if you vote negative comment why so you can help me out here. I won't be mad lol
When I got this, I had bought the Pepper on the Kudos Wall for about 900 KP. It let's me have 2 extra hints and 1 skip. It may not seem like much but it's what got me through. I'm sure there are others better than the Pepper, but I have not unlocked them yet. The Pepper is in the 2nd row down and it's the 3rd one over.
Make sure to only answer the questions you know. Don't risk losing lives. If you can get to 7 or 8 without losing a life or hint, then you're doing pretty good. You get about 4 or 5 skips with the Pepper, plus 5 hints giving you another answer, then the oust which is another answer, then make sure you have about 200KP left over so if you don't make it to 20, you can revive and give it another shot.
