Device for decoding or for rapid reading of grids of forecasting games, comprising, as in the case of the game of Lotto (Bingo), several numbered boxes of which only some among them have been marked by a sign such as crosses made with ball pen or similar means before knowledge is gained of the winning numbers. Each device consists of a small rigid decoding plate 10 pierced with a window 14 which is cut out precisely to the actual dimensions of a game grid in order to be able to coincide exactly with the said grid, the window being provided over its entire opening with a translucent sheet 16 on which it is possible to draw in an erasable manner, for example by means of a felt pen, the outline of boxes for the winning numbers after having applied the small decoding plate 10 over a grid. <IMAGE>
