Pick-up sticks or pick-a-stick is a game of physical and mental skill. A bundle of 'sticks', between 8 and 20 centimeters long, are held in a loose bunch and released on a table top, falling in random disarray. Each player, in turn, must remove a stick from the pile without disturbing the remaining ones. One root of the name "pick-up sticks" may be the line of a children's nursery rhyme, "...five, six, pick-up sticks!" The game has spawned several variations such as Jackstraws (or Jack Straws), Spellicans, and Spillikins.
