1. A game apparatus comprising a plurality of substrates having a plurality of indicia applied to a portion of a surface of each of said plurality of substrates for viewing by a player of the game, each of said plurality of substrates having thereon means rendering the indicia thereof invisible at a first temperature so that the indicia cannot be read by the player, said means being actuable by a change in temperature thereof to a temperature significantly greater than that obtainable by simple contact with the body heat of the player to render the indicia visible for reading by the player, wherein there is provided on each of said plurality of substrates at least one further indicium and coating means obscuring said further indicium, the coating means being removable only in a manner which leaves the further indicium permanently exposed, wherein a winning substrate is indicted by the presence of a common indicium both on each of the indicia of the winning substrate of said plurality of substrates, and on said at least one further indicium of the winning substrate.
