This is a device making it possible, in particular, to play number lotto and, in general, forecasting games. The device is composed of a set of two small plates used in turn jointly on a paper sheet. One of the small plates (Fig. 2) has a dual function, that of being a template via its square or rectangular perimeter and that of being an identification table of the numbers to be played. The other small plate (Fig. 3) acts as a grid pattern (master) including holes (2) which make it possible to check off numbers to be played. <IMAGE>
