Wikipedia: Stoop ball
Stoop ball (also spelled “stoopball”) is a game that is played by throwing a ball against a stoop (stairs leading up to a building) on the pavement in front of a building. Historically, it has been popular in Brooklyn and other inner cities. It first became popular after World War I.
 
Rules
There can be as few as one player per side. Sometimes there are 3 players (one infielder, two outfielders) on each side.
 
The “batter” throws a pink rubber ball (either a “spaldeen” or “pensie pinkie”) at the stoop. The ball flies back towards the fielders, who are also facing the stoop.
 
Outs can be strikeouts (if the ball misses the edge of step), but are more likely to be fielder outs (a caught fly ball or a grounder). Hits are determined by distance of ball flight, or whether it hit the ground without being caught.
 
Alternatively, the person throwing the ball catches it on the fly or on a bounce. Each time a ball hits the stoop and is caught is worth 10 points. A “pointer” is a ball that hits the edge of a step and comes back as a hard line drive that could “take your mouth out.” Catching a pointer on the fly is worth 100 points. Usually the winning score is 1,000 points, but it could be anything agreed upon.

Stoopball rules
1. One team is in the field while the other team is at bat. The batter faces the building and throws the ball at the steps as hard as he/she can. The ball must hit the steps and bounce back into the street.
2. The batter is out if someone in the field catches the ball on a fly.
3. Otherwise, it is a hit. The number of bases the ghost runners advance is determined by the number of times the ball bounces before it is caught.
(1 bounce = single, 2 bounces = double, 3 bounces = a triple, 4 or more bounces = a home run)
Another way to score is if you bobble the ball, it’s a single. If the ball gets by you untouched, it’s a double. Hits can be determined by the distance of the ball flight.
4. If the ball goes over your head, it is an automatic home run.
5. Make sure to keep track of your bounces and the locations of your ghost runners. Runs are scored the same as in baseball. There are three outs per team per inning. You can play a seven-inning or nine-inning game.

The boy, whose father, James Monmouth Purdy, is a process server at the Jefferson Market Court, got home from Public School 03, at Ninety-third Street and Amsterdam Avenue, early in the afternoon, and, with some ten or a dozen other boys in the block, began to play “stoop” ball in the street.
 
Walter stood in the gutter, just off Columbus Avenue, in front of 101 West Ninety-fourth Street, throwing the ball against the stoop steps, and catching it when it rebounded.

Often, we were savagely smacking a little ball around in a variety of ways. We used the hollow rubber sphere, worth a nickel then, to play stickball, punchball, stoopball, stoop baseball and box ball, to name but about half of them.
 
Stoopball was a simple but fascinating game for us. As the name implies, it was played against a stoop—a cement stairway leading up to a house. From about 12 feet back, the ball was thrown against the stoop and caught on the rebound. If the ball bounced once before being caught, the player got 10 points for the throw. If it bounced more than once, he forfeited the ball until his next turn up. If he caught it on the fly, he got 100 points. The game was won when the first person reached 1000.
 
The new generation of youngsters in he East still plays stoopball, but the great competitive fire which brightened the game for us seems to have dimmed under the new order. They don’t play it as often these days, or with the same spirit.

STOOPBALL. Three players on each team play seven innings. Game is played by hurling Spaldeen against the point of a step or stoop. Fielders try to catch ball on the fly to retire batter. Hits are registered by the number of bounces ball takes before fielder grabs it. One bounce, a single; two bounces, a double, and so on.
