a processor configured to define a current gaming session based on said data indicative of at least one of the gaming session rules from said non-transitory readable memory;

a wagering threshold determiner configured to determine a wagering threshold to apply to play of at least one gaming device during the current said gaming session based on 1) an average of said amount wagered in a plurality of prior gaming sessions, and 2) said return-to-player amounts for said at least one gaming device;

an event controller configured to trigger an event upon the wagering threshold being reached in the current said gaming session; and

wherein the wagering threshold determiner is further configured to determine a plurality of different wagering thresholds to apply to a said current gaming session, each said different wagering thresholds being based on a different return-to-player amounts.

16. A gaming system as claimed in claim 15 , wherein the wagering threshold determiner is further configured to determine the wagering threshold as a percentage of said average.

17. A gaming system as claimed in claim 15 , wherein each of the different wagering thresholds corresponds to a plurality of different return-to-player amounts.

18. A gaming system as claimed in claim 17 , wherein said different wagering thresholds is a different percentage of the amount wagered in a prior gaming session.

19. A gaming system as claimed in claim 15 , wherein the wagering threshold determiner is further configured to determine the wagering threshold based on a defined period.

20. A gaming system as claimed in claim 15 , wherein the wagering threshold determiner is further configured to determine the average amount wagered based on a plurality of prior gaming sessions within a defined period of time.

21. A gaming system as claimed in claim 15 , wherein the wagering threshold determiner is further configured to determine the wagering threshold from an amount wagered by an individual player.

22. A gaming system as claimed in claim 15 , wherein the wagering threshold determiner is further configured to determine the wagering threshold from an amount wagered by a group of players.

23. A gaming system as claimed in claim 15 , wherein the wagering threshold determiner is further configured to determine the wagering threshold from an amount wagered on an individual gaming device.

24. A gaming system as claimed in claim 15 , wherein the wagering threshold determiner is further configured to determine the wagering threshold from an amount wagered on a group of gaming devices.

25. A gaming system as claimed in claim 15 , wherein the event controller is further configured to confer a benefit of said event on a player of the at least one gaming device.

26. A gaming system as claimed in claim 15 , wherein the event controller is further configured to make an award to a player of the at least one gaming device.

27. A gaming system as claimed in claim 15 , wherein the event controller is further configured to provide information of said event to a player of the at least one gaming device.

28. A gaming system as claimed in claim 22 , wherein the wagering threshold determiner is further configured to determine the wagering threshold from an amount wagered by a group of players.

29. A gaming system as claimed in claim 22 , wherein the wagering threshold determiner is further configured to determine the wagering threshold from an amount wagered on an individual gaming device.

30. A gaming system as claimed in claim 22 , wherein the wagering threshold determiner is further configured to determine the wagering threshold from an amount wagered on a group of gaming devices.
