  • Patent number: 5217258
    Abstract: A break open game ticket comprises a first and second substrate laid back to back. Each substrate includes an upper half which includes information concerning winning combinations of symbols and a lower half which includes three break open panels. One substrate is inverted relative to the other substrate so that the panels of one are aligned with and overlie the information section of the other thus keeping the panels entirely separate. The panels on one side can therefore be opened to expose the combinations printed on the backside of the information area of the other substrate. The games are thus independant and provide a novelty effect improving the pleasure of the game player.
