Keep playing until you win, just hit refresh if you get the wrong answer. Pretty simple quiz. I got it in 2 tries without even reading the website.
How to Play
1. You will be shown randomly chosen questions, each with four possible answers.
2. If you click on the ‘clue’ icon you will be shown a page from the website that contains the answer (don’t forget to read down the whole page).
3. Pick your answer and click on ‘check my answer’ to see if you are correct
4. Finally, click on the ‘submit’ button at the end of all the questions. Good Luck.
5. Answer all the questions correctly and you win the prize – simple.
