An instant lottery scratch ticket and method of playing a lottery instant scratch ticket game comprises a plurality of physical tickets, wherein each ticket provides a removable sticker that may provide wins or enhanced wins.

A playing card having a substrate entirely of a first predetermined colour overlaid with a removable surface coating entirely of a second predetermined colour contrasting with said first predetermined colour, said removable surface being sufficiently friable so as to be able to be scratched off by a player in a pattern predetermined by said player to reveal said substrate in said pattern. The scratched playing card uses the high contrasting colors (typically primary and secondary colors) to produce letters or image(s). These cards are interchangeably used in a strategic and non gambling card game often utilising the Stroop effect.

A security-enhanced document, such as an instant lottery ticket, includes a substrate. Indicia is provided on the substrate, and a scratch-off-coating (SOC) layer is applied over the indicia to maintain the indicia unreadable until removal of the SOC layer. The indicia is printed onto the substrate as pigmented particles. One or more opacity film layers may be provided over or under the pigmented particle indicia.

A lottery ticket dispenser array includes a frame and a plurality of separate bins contained within the frame. Each bin includes a housing having a front side that faces a purchaser in operational use of the dispenser array, an opposite back side, and an internal space for receipt of a supply of interconnected lottery tickets, wherein each lottery tickets contains a code printed thereon. Each bin has an electronic drive mechanism that dispenses the lottery tickets therefrom. The bins are separately removable and insertable into the array. A printer module is provided in the array and has a size and configuration so as to be insertable into the array in place of at least one of the bins.

An instant lottery ticket game structure and method includes a set of instant lottery tickets, wherein a plurality of these tickets are winning tickets having a predetermined first prize value, as well as a predetermined enhanced second prize value. A first validation file is maintained in a central host computer having a primary record for each winning ticket, the primary record including ticket identification data and the predetermined first prize value. A second validation file maintained by a computer includes a base record for each winning ticket having the prize enhancement code for the winning ticket and the second prize value assigned to the winning ticket. A logic gate in the base record automatically activates upon entry of the prize enhancement code, wherein the computer creates a final record for the winning ticket by modifying the base record to include the second prize value as a final prize value. The first validation file is periodically updated with the final records.

Disclosed herein is an electrostatic ink composition comprising a component selected from a fatty acid ester having a plurality of hydroxyl substituents and a fatty acid amide having a plurality of hydroxyl substituents. Also described herein are scratch-off structures and methods for producing them.

A method is provided of digitally imaging a secure portion and a non-secure portion of scratch-off-coating protected documents of at least one game using middleware. The method includes: (a) generating the secure variable indicia in non-vector raster format; (b) generating vector graphics to be imaged on physical document locations; (c) assigning the secure variable indicia in a non-vector raster format to documents in and shuffling the documents throughout a print run; and (d) linking via middleware the secure variable indicia in the non-vector raster format to associated vector graphics variable indicia to be digitally imaged on the documents and to generate vector graphics-formatted data for each document in the print run. The secure variable indicia assignment and shuffling are executed by non-vector raster game generation software output that is reinterpreted by the middleware to produce related vector graphic output for the secure variable indicia.

A redundantly printed security-enhanced document, printing method, and system for better ensuring that the meaning of the information imparted by variable indicia printed by redundant printing indicia on a document protected by a removable Scratch-Off Coating (SOC). By printing the variable indicia with multiple colors, redundancy and integrity of the intended indicia is achieved relative to the perception of human eye photoreceptor cones. The redundantly printed document, methods, and systems enhance the overall appearance of the redundantly printed document, and reduce possible consequences resulting from misprinted variable indicia.
