An electronic gaming machine (“EGM”) comprising:

• a cabinet;
• a display screen;
• one or more input buttons;
• a credit input device;
• and
• control logic configured to perform operations to control a user interface of the EGM, the operations comprising:
• displaying on the display screen a first state of a reel game before a final wager for a next play of the reel game is initiated, the display screen in the first state including a progressive jackpot display area for an available progressive jackpot award, the progressive jackpot display area displaying a first progressive jackpot amount in the first state;
• and
• displaying on the display screen a second state of the reel game before the final wager for the next play of the reel game is initiated, the display screen in the second state including the progressive jackpot display area, the progressive jackpot display area in the second state displaying a second progressive jackpot amount, the second progressive jackpot amount being different than the first progressive jackpot amount;
• and
• displaying on the display screen a third state of the reel game responsive to a win of the available progressive jackpot award, the display screen in the third state displaying an outcome for the available progressive jackpot award, the outcome having been determined using a selected multiplier value and a third progressive jackpot amount, the third progressive jackpot amount having been determined by incrementing the available progressive jackpot award by a percentage of a bet amount, wherein a selected increment rate indicates the percentage, the selected increment rate having been selected from among multiple increment rates associated with different bet amounts, and the selected multiplier value having been selected from among multiple multiplier values associated with the different bet amounts, subject to a product of multiplier value and increment rate for each of the different bet amounts being uniform across the different bet amounts.

• and
• a game controller configured to generate the multiplier value by selecting among multiple multiplier values associated with different bet amounts, and to display the generated multiplier value in the second display area, the game controller being further configured to:
• compute an updated value of the jackpot award amount by incrementing the jackpot award amount by a percentage of a bet amount, wherein a selected increment rate indicates the percentage, the selected increment rate having been selected from among multiple increment rates associated with the different bet amounts, subject to a product of multiplier value and increment rate for each of the different bet amounts being uniform across the different bet amounts;
• and
• responsive to a win of the jackpot award amount, determine an outcome using the generated multiplier value and the updated value of the jackpot award amount.
