Unfair dice are seldom submitted for inspection, as may well be imagined, particularly those of the dispatcher kind. The greatest donkey in existence would at once find that the number of pips upon the faces of these latter was incorrect. Therefore they are always introduced into the game whilst the play is occupying the dupe's undivided attention, and the manner of their introduction is that embodied in the process known as 'ringing-in.' This is done at the moment when the dice are taken up in order to throw them into the box. It is only possible to change one die, the others are allowed to fall into the box in the usual way.
Supposing that two dice are being used, two fair ones will be employed, and with these the dupe will throw. The sharp, however, has a false die concealed in his right hand, and held in the thumb joint. He picks up the two fair dice from the table, in the manner described in 'securing,' and allows one of them to fall into the box. Then, of course, he has still two dice in his hand, one genuine one between his fingers, and one false one held by his thumb. In figs. 55 and 56, a is the genuine die and b is the false one.

At the same instant that the first die is allowed to fall, the false die b is dropped into the box also (fig. 56).
