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.
