Sizes in order (as far as I can remember)
littlies
jacks
biggies
queenies
Kings
ali bompas (these were rare)
Then the types:
normal
cat’s eye
joker’s lips
zulu
clearie
spotted dick
oilies
ball bearians (actually ball bearings but we seemed to have a hard time getting that right)
EDIT and chinas too yes
Now, how did you play the game? When we did it you had to hit the other person’s marble for a win, but the ratio was decided on value. So to win a biggie with a littlie you had to hit them twice but they only had to hit you once, so you’d say ‘twice-once’ at the beginning of the game and you’d tap him twice and he’d tap you once, like boxers touching gloves I suppose. The ratios for the sizes were well recognised but there’d be plenty of argument with regards the value of the specials.
Now my memory gets dim here, but there were loads of special moves you could call, like if he landed really close to you but didn’t hit you could call ‘drops’ where you stood up and dropped the marble on his. there were many of these calls but I’ve compleltey forgotten.
