The invention refers to a lottery ticket containing a crosswords puzzle square, destined to the public as an instructive-educational and recreational game, in order to obtain certain immediate gains in cash or in objects as well as an advertising means. The lottery ticket is presented under the form of a plane support (1) having pre-printed on a side of the square (2) of crosswords puzzle, proposed for solving. In a field (h) are pre-printed definitions (i) that are covered by a screen-layer (j), opaque, containing an inscription "grate here!" On the same side the solution to the square (m) is printed, at a much reduced scale, in normal position or rotated by 90° or by 180°. The solution to the square (m) is also covered by an opaque screen-layer(n) containing the indication "after solving grate here!" Certain control series (r and s), covered by a screen-layer will be used by the organizer for validation purposes. The screen-layers (j and n) can easily be grated out by the edge of a tough object.
