Claim:
A method comprising: determining, by a lottery server in communication with at least one player device, a total number of lottery numbers matched by a player in at least two lottery drawings; and providing a bonus to the player if the determined total number of lottery numbers matched is not less than a minimum number of lottery numbers matched, in which determining the total number of lottery numbers matched comprises: comparing, by the lottery server in communication with the at least one player device, a first set of numbers from a first lottery entry to a first set of drawn numbers to determine an occurrence of a first matched number, associating, by the lottery server in communication with the at least one player device, the occurrence of the first matched number with an expiration criterion for determining whether the occurrence of the first matched number qualifies for the bonus, in which the expiration criterion is not based on a predetermined specific time, and comparing, by the lottery server in communication with the at least one player device, a second set of numbers from a second lottery entry to a second set of drawn numbers, in which the first set of numbers from the first lottery entry is different than the second set of numbers from the second lottery entry.
