You need to get correctly answer questions 1-10 without losing lives or using power-ups.
This comes down to mostly luck. You need to get a good string of questions that you can answer easily. If you are stuck, it's probably better to just restart. You can take your time on this one, so feel free to Google the answers or use the spreadsheet
being put together by dedicated community members (if you use this, PLEASE contribute any answers that are not on there; don't just take).
The timer is a total of 2 minutes at the start, and each question you answer gives you back some time. I recommend playing with the game snapped to the side and have a tab in your browser ready to look up answers.
Completing this achievement will also net you 'Ten In One' if you don't have it already.I completed the requirements for this achievement several times, but it did not pop. It only unlocked when I went into the achievement tab in game. Don't know if this is buggy, or if it was an isolated case. Try that if it gives you trouble.
