Answer as many questions as possible! If you can, take a minute to search for the right answer. If not, just give it a try you don't lose points for giving the wrong answer. Questions change every ten minutes, so make sure you're here on time for the next one.
Add a new question whenever you can (that is when there's an open slot in the queue and none of the questions in the queue were originally submitted by you). You get 8 points for adding a question so thats almost as high as getting three answers right! Remember to submit questions that follow our guidelines and don't spam the system. You could get penalized for submitting a question that is in breach of the guidelines and so lose points rather than gain them!
Small tip when you have a minute, compose a few questions of your own and keep them under your hand. That way, when a spot is available for you to submit a question you can do it quickly and effortlessly.
Refer new players! This is probably the best way to gain lots of points fast! For each referred player you get 15 points that's like answering 5 questions correctly!
To refer new players, simply visit your account page and copy the referral code there (highlight it with your mouse and click control+C to copy, then use control+V to paste it elsewhere).
Use that code anywhere you can think of in your email signature, in forums signatures (where allowed of course), on your website anywhere! Accompany it with a catchy invitation too. Actively email your friends and tell them about this site. Invite them to register with your referral code.
Get your referrals to refer new players! For every such second-tier referral you will get 5 points! When you invite new people to play, tell them about how referring more players is good for them and for you. If you refer just 5 friends and get each of your referred players to refer another 5 friends each, you will have 100 points under your name!
