Abstract: A pack of lottery tickets includes a plurality of inter-connected lottery tickets fan-folded into a stack, wherein each lottery ticket comprises a first side edge. A code on each lottery ticket identifies the pack and an order or position of the lottery ticket in the pack. A marking pattern is printed along the first side edge of each of the lottery tickets and includes at least one mark. The pack has a side face defined by the stacked first side edges of the tickets in the stack, wherein the marking pattern on the lottery ticket side edges align so as to form a unique identification image on the side face of the pack. The marking pattern on each lottery ticket is unique to the respective ticket such that each lottery ticket in the pack can be separately authenticated at a later time by comparing its marking pattern to a retrieved or replicated image of the marking pattern based on the pack identification and order of the lottery ticket in the pack provided by the ticket code.

Abstract: Methods and systems for securely generating lottery games are presented. A final game generation seed number is formed from multiple seed numbers from multiple and differing parties such that no one party has the ability to create the final seed number without the other parties' consent or knowledge. Since the final seed number is required by the software that governs the distribution of prizes within a game and is therefore required to produce valid game data, no one entity would have enough information to determine the location of a winning prize. This creates an environment of transparency such that all parties must agree on the terms that result in the formation of the final seed number from the individual seed number fragments in order to produce a game.
