A flash sale mechanic of a virtual game may perform a flash sale transaction based on transaction details for the flash sale transaction. These transaction details may indicate an item for sale, invitation requirements applicable to a player of the virtual game, and transaction requirements applicable to participants of the flash sale transaction. The flash sale mechanic may selectively provide an invitation request to a first player of the virtual game based on the invitation requirements of the flash sale transaction, and may receive acceptance responses from players that choose to participate in the flash sale transaction. The flash sale mechanic may complete the flash sale transaction if it determines that it has received an acceptance response from at least a minimum number of players that are needed to complete the flash sale transaction, and that these players have satisfied the transaction requirements.
