PLayers take turns removing counters from one or both piles; in the latter case, the numbers of counters removed from each pile must be equal. THe game ends when one person removes the last counter or counters, thus winning. MArtin Gardner claims that the game was played in China under the name ji n shíz ("picking stones"). THe Dutch mathematician W. A. WYthoff published a mathematical analysis of the game in 1907.
