Abstract (en)
[origin: WO9501821A1] Game tickets are printed with a number of layers including an opaque abradable or scratchable layer (22, 38, 40) which is removed by the user to reveal the ticket game indicia layer (18, 32). The ticket uses a relatively light permeable substrate (10) and to prevent the game indicia (18, 32) from being illicitly read by shining an intense light at the rear of the ticket, the layers embody a confusion pattern layer (12, 36) under the abradable layer (22, 38, 40) which registers with the game indicia.
