Hexagrams

[Thumper]

Not being much of a SWP player, I have to say that this game is great.
I can't remember a quiz game where I can so consistently win, OK only a pound or two in a go, but I have on numerous times walked away £4/5 up (which for me is good!)
A couple of questions though if anyone knows the answers..
After reaching £2 there is an extra time square three questions on. How much time does this give you? I have never been confidant of having enough time to reach it but would be interested to know.
Also how much further is the next prize level?
Finally, what is the most anyone has won from a go?

once you hit the extra time bonus, there is always another such bonus every two levels until the top (which is a fiver). (unless the game has been done over, in which case the first extra time comes before any prize and the top of the stack is only £1.)
