How Did a Few Pebbles Become a Blocking Game on the Ground?

In some places, children drew a tiny line diagram on the ground with chalk, a brick fragment or a stick, then found two distinguishable sets of pebbles, apricot stones or bottle tops. The game was often called biesiniu, meaning roughly “block the ox”. Its name, board and opening arrangement varied by region, so no single ruleset should be treated as universal.

In one common version, each player had two pieces and took turns moving one along a line to an adjacent empty point. Pieces could not jump, and winning did not depend on capture. The aim was to leave the opponent with no legal move. With only a few intersections, the position could reverse quickly: an apparently forward move might open the only escape route for the other player.

For some children growing up from the late 1960s through the 1970s, almost everything needed was already at hand. A few lines created the board during a break; a sweep of the hand erased it when the bell rang. Onlookers suggested moves and argued over whether a diagonal counted as a path. This was less a miniature formal chess set than a temporary order sustained by local memory, shared names and rulings among peers. After a loss, the pieces were reset and the analysis happened through the next game.
