Low-Tech Childhood Games
Anyway. My all-time favorite childhood game was "Kick the Can." You know, where everyone hides and the "it" has to spot the people as they creep in to base to try to kick the can and free all the people who've already been caught? Strict integrity on the part of the "it" is required, I realize, looking back.
"Capture the flag" is another good game, but it requires rugged terrain (to maximize the opportunities for sneaking through poison oak) and a good number of people.
I also frequently played a perverse variant of "Cowboys and Indians," in which the Cowboys spent most of the time in the Indians' jail and had to try to break out. The older kids were always the Indians and seemed to enjoy offering us Cowboys regular meals of mashed-up leaves. The jailbreaks were always futile, by the way. "Cowboys and Indians" flat-out sucked for the Cowboys.
Another great game I played as a kid we called "Duck on Rock," although, according to this source and this one, it's more usually called "Duck on a Rock" or somesuch. We played it roughly according to the "medieval version" described in the first link, but we usually built up a cairn of rocks instead of using a tree-stump.
What fun, ultra-low-tech games do you remember?
