Device for checking the grids of games with marked-off squares (boxes) corresponding to numbers. The invention relates to a device which makes it possible to read, without the risk of error, grids of games in order to check whether or not they comprise winning numbers. It consists of a sheet of paper 1 with a high G.S.M. having as many pre-cut-out squares (boxes) 2 as there are squares (boxes) 6 in the game grid 5 in question. The user detaches the squares (boxes) 2 corresponding to those of the winning numbers by pressing with the aid of an object such as a pen tip. The lower part 4 is pre-folded 3. Its folding permits guiding of the game grid 5 over the sheet 1. Its upper part comprises a window 8 corresponding to a precise location 7 of the game grid in question and serving as reference. The application of the game grid 5 over the sheet 1, taking its guide 3, its reference 8 and its detached squares (boxes) into account, permits perfect reading of the squares (boxes), whether or not these are marked off. The device according to the invention is intended particularly for checking grids of games such as the National Lottery. <IMAGE>
