I used to play fuzz buzz too in my youth. I know HarryO is from Manchester, Iam too originally, allthough living in Canada now. Is this a regional thing only known locally ?
To play the game, basically everyone sits around the table. With a pint in a dimpled glass. One person starts to count, starting with the number (shouted) "ONE" the numbering goes around in a Clockwise direction, the next person shouting "TWO" this continues. The thing which you have to remember is that the number 5, anything divisible by 5 or any number with a 5 in it is a "FUZZ" not the number. Similarly anything with a 7 or divisible by 7 is a "BUZZ". Numbers like 35, or 57 (if it gets that high) generally become something like "FUZZ BUZZ" Any mistakes result in the perpetrator having to drink a "Window" (one level of dimples) of beer from the dimpled pot. Hence the alternate name for the game of "windows".
We soemtimes added variants on other numbers, like a certain number ie 9 reversed the direction of counting, therfore 99 would reverse twice and continue in the same direction. A 2 would miss the next person.
OK basically it is a divertion used to get people as pissed as possible in the minimum ammount of time. You really have to have played it to understand it, or Not.
