They are the easier ones supposedly, it is to stop people looking up the answers, but once someone plays I don't think we can alter the times (Rugger/Duc ?), but as its new we welcome any feedback but we need to know which quiz you mean. If people think they are too easy or too difficult then let us know, but remember it's a wide audience that we have.
I only have like 10 seconds per question to answer - if you watch a clock 10 seconds is a long time, the minimum we have is 12 secs per question, but if more people feel the same we can give you more time in the future. You do get more time on the harder quizzes, the easier ones generally you either know or don't, for example your post above took me 4 seconds to read, which leaves 8 seconds to pick out the right answer.
Just so you know we tested them out on each other and didn't have any time problems?
