A grid for filling in lotto coupons (4) comprises an upper plate (5) with a plurality of straight lines of parallel perforations (6), as well as a plurality of straight lines of intercrossing perforations. Favourably, the lines of perforations surround several rectangles (7) having equal dimensions and located at the same distance with respect to each other and said rectangles are surrounded on all sides by ribs (8) which separate them. On at least two adjacent sides of the ribs surrounding one rectangle, there is arranged one protuberance (1, 10), the protuberances being connected inside the rectangle by a platelet (11) which is pressure-detachable from the grid. |
