Also called &amp;quot;the boneyard;&amp;quot; however, the term &amp;quot;the boneyard&amp;quot; is typically used in matching and scoring games and usually refers to tiles that are purposely not drawn at the beginning of the game, so that players can draw from the boneyard during the game when they do not hold a playable tile in their hand. The term &amp;quot;widow(s)&amp;quot; is typically used in bidding games and usually refers to the tile or tiles left after each player draws their hands from the deck at the beginning of the hand and there are &amp;quot;widow(s)&amp;quot; because the number of tiles can not be divided equally among the number players.&lt;/p&gt;
