Okay, I thought these were a little easier, But.. I do 20 questions every Sunday for my local club, and they're tackled by individuals, or tables of up to 4 people.
I pride myself that I rarely need a tie break for two (or more) scores of 20; the top score is usually in the 17-20 range, and rarely does anyone/ any-one-team score less than 10.
As I ,obviously, start off knowing them all, it requires careful targetting.
And this month I need to do an extra 4 pages of 20, as we have a charity quiz if there are 5 Tuesdays in the month.
Just a little useless background!
