In our common forfeit games, too, mental contest often forms the basis of the fun. For instance, it is a distinct attack and parry when a handkerchief is thrown to a player and a word pronounced to which he must find a rhyme. In English, where the spoken and written words are so unlike, the spelling of unfamiliar words is turned into a game; and another idea is to introduce into a story some object or incident suggesting the name of one of the players, whereupon he must continue the recital, passing it on to another in the same way. Or a passage from some great author may be cited and his name guessed, and many similar devices. Finally, we mention the important group of plays for which the stimulus is partly intellectual experimentation, but is primarily attributable to the combative instinct, such as board and card games, both of which are symbolic of physical contests in which the players appear as leaders of opposing forces and originators of strategic operations. A genuine battle ground is afforded by the board, and the great object is to have the right man in the right place at the right time. In cards strategy is exhausted in the choice of the right champion at the right moment, but is rendered much more difficult by the fact that the former contestants have disappeared from view, while the reserve is concealed. Thus it results that board games afford opportunity for the display of skill in arrangement and card games especially cultivate memory, while both are important promoters of the logical faculty and of imaginative foresight.[386] An important distinction between them is that in board games the strength of the contestants is exactly equal at the start, and the material chances are identical, while in cards inequality is the rule.
