My older brother (age 84) described ringolerio to me yesterday. Each team had 5 guys. One would place himself with his back against the wall while the other four would hold on to him and each other in a squatting/stooped position. The other team would then run and jump on the backs of the squatting guys with the aim of making them fall to the ground. I vaguely remember playing this but am not sure what we called it. This was in the late 1940s in Inwood Manhattan
