A secondary game system, in various embodiments, comprises a system of networked game terminals where a player playing a game on a game terminal can earn eligibility to win a prize from a secondary game that plays simultaneously in the background. The secondary game may be triggered based on play on the plurality of networked terminals. This allows the player to play a first game that earns them eligibility to win another game that is played in the background. The player sends a game initiation request for a game (e.g., lottery slot) to be played on the game terminal. If a certain criterion is satisfied, the player becomes eligible to win a prize from the secondary game if the secondary game is triggered while the player is eligible to win.
