Kids just need chalk and some bottlecaps to play this simple sidewalk game.
The object of this classic game is for players (you'll need two or more) to land their bottle caps in the numbered squares

To set up, use chalk to draw the board shown at right on a patch of pavement
(ours was 3 feet square).
To start, one player sets a cap on the starting line and flicks it, trying to land it in the 1 box without touching a line. If he succeeds, he leaves the cap in that box and goes again, shooting another cap at the 2 box, and so on. If he misses, he collects that cap and the next player takes a turn.
If a player hits another's cap out of a box, he places his in that box and continues shooting (the other player has to shoot for that box again).
If a player lands his cap in the square around the 9 box, he loses two turns.
The first player to get a cap in all nine squares wins.
