Growing up in the state of Delaware, I, too, played a lot of Seven-Up. What I remember was first you played the rounds with both hands followed by one hand. Then it was a clap before the catch, next time you rolled your hands around each other then crossed your arms placing hands on shoulders. After that was one bounce, then bounce ground to wall then under the leg and finally the spin. Taking for granted my memory is even close to clear at my age this is how I remember my daily game always played sometime between lunch and supper.
