A first random number generator using a first prize table selects physical locations in the deal of tickets for the plurality of predetermined non-jackpot winning tickets, and the plurality of variable jackpot tickets. A second random number generator using a second prize table different than the first prize table selects a jackpot prize for each of the plurality of variable jackpot tickets. Some of the jackpot prizes in the second prize table are less than the expected value. The difference between some of the jackpot prizes in the second prize table and the expected value are used to fund one or more jackpot prizes that are greater than the expected value. ## Claims ### Claim 1 A method of providing variable jackpot tickets for a game defined by a plurality of tickets that are preprinted with game content and which are associated with a deal of tickets, the deal of tickets including (i) a plurality of predetermined non-jackpot winning tickets, and (ii) a plurality of variable jackpot tickets, and wherein the plurality of variable jackpot tickets have a predefined expected value, the method comprising: (a) executing a first random number generation using a first random number generator to select physical locations in the deal of tickets for (i) the plurality of predetermined non-jackpot winning tickets, and (ii) the plurality of variable jackpot tickets, wherein the first random number generator uses a first prize table for the selection;
