We used to play fives with five bits of shingle from the beach. Rules as per fivestones. No ball just lightning fast digits.
Clever kids played with ten bits of shingle but still called the game fives.
Big sweep was picking up all nine stones on the ground whilst throwing the tenth up and catching it with the same hand. Only older kids played it because youngsters hands were too small to hold ten stones.
Little sweep was to pick up four whilst throwing up the fifth. A kind of junior version of big sweep.
