ring a ring a roses
off ground tick, knock and run, forts, piggy in the middle, blind mans bluff, leapfrog, hand stands, cartwheels, catch
there was also the hand clapping ones, where 2 kids - girls mainly - would do a kind of clappy routine while singing a rhyme
we also had one with a tennis ball in one leg of a tight, and you stood back to the wall and banged it on the wall either side of you in formation - it wasn't great admittedly
there was also my favourites - picking scabs, eating puddle ice and drawing on your skin
eeh, them wert days...
