Excellent thread guys - very thought-provoking. I've never been a pro in the sense of relying solely on quiz machines for a living, although I may have come close a few times, but I have played through all the 'eras' of the machines from Give Us a Break to Nuts (although archaeologists of pre-history do tell of a game called Tic Tac Triv which apparently pre-dated even Give Us a Break :wink

As for the "pros = parasites" debate, I'd say that you could probably group all games into three categories in terms of their 'winnability':
A. Cash Cows - those games where with a certain level of skill/knowledge/inside information etc you can win a decent prize (Jackpot or close) more than once without the game changing its playability radically. These have always been few and far between obviously and they are often a personal thing - I have witnessed people winning successively on games I wouldn't even have got £1 on myself. This category would include the original Quizmaster, Silver Falls, Word Up, Spelvin, Pepsi Quiz, Spot the Difference, Triple Towers, ...
B. Cyclical Payers - these games are set to follow a pattern of getting relatively easier to win on as more money goes into them, until the point when the Jackpot becomes attainable for those with the required abilities. After the JP has been won, the game resets itself to become very difficult but the cycle starts up again straight away. Real Millionaire was the classic example of this but think also of Treble Top, Gold Digger, Top of the Pops 2, Ant and Dec, Hangman, Every Second Counts, Guinness Book of Records, ...
C. No Hopers - these are games where the prize structure, the length of games and the early appearance of spoilers make them 'non-cyclical'. They are often set so that £1 or £2 is relatively easy to win with a bit of practice but they seem never to get close to making anything better than that realistically achievable, no matter how many losing games are played. Many modern games are like this - Monopoly Deluxe, Bullseye, new Cluedo, Mousetrap, Risk, the two Mike Reid games, Fantastic Four, Spiderman, Pink Panther, Hex Appeal, ...
Clearly pros will be looking to identify and exploit Type A games, and we can all see how those games will be frowned on by pubs and the SWP industry.
I personally mourn the virtual disappearance of Type B games as those are the ones for me that are 'win-win' for nearly everyone, even those dastardly pubs and SWP companies. Good prizes are available and with hard work and dedication you can get to the level where you can exploit the games when you realise they are at the top of their cycle but once you have won the big prize the game will be reset to ensure the machine still makes a profit. The point with these games was that non pros would sometimes see the machine in the high end of the cycle, at which point they could often win a nice prize of £4-£5, which made their experience of playing the games more enjoyable and was much more likely to encourage them to play again on the same game, and maybe in the multi-game world to check out one of the other games.
For me it's the type C games that are wrecking the SWP experience. Pros realise how futile the games are but because they are set so that the higher prizes are always unattainable, NO ONE one ever sees a large win happen and NO ONE one ever gets close to one themselves, no matter what level of ability they have. They rapidly become ignored, and are removed from the machines only to be replaced by some other waste of time.
Now it may be that it's the very small number of true pros that have over the years caused the SWP industry to move further and further down the line of just making Type C games, but personally I'm not so sure. For a long time pubs were
generally happy to see a large win because (a) it encouraged other players as they could see it was possible to win and (b) they knew that the games would soon claw back the money paid out (in truth the games would usually only pay out once the required cash had been taken in the first place)
As for whether we can all contribute to a forum like this, I'd say that we surely can. There may be 'lurkers' who come on simply to read messages and hope to pick up information but who never actually post themselves (although maybe the removal of non-posters at the weekend has helped with that) but on the whole I'd say that most people on here have something useful to contribute and that this forum is refreshing free of the inane swearing, name-calling, pointless gossip and so on that most similar sites get swamped by.
Keep up the good work guys!
