(i) spin and stop the plurality of symbol-bearing reels to display a symbol combination representing a free spin outcome based, at least in part, on the one or more random elements;

(ii) in response to the displayed symbol combination being a non-losing outcome corresponding to a minimum award threshold, decrement the number of accrued guaranteed wins and grant an award corresponding to the displayed non-losing outcome;

(iii) decrement the number of the accrued free spins; and

(iv) repeat (i)-(iv) until the number of accrued free spins equals zero; and

in response to any accrued guaranteed wins remaining after completing all the accrued free spins, display the spinning and stopping of at least one cash-spin reel for each of the remaining accrued guaranteed wins, the spinning and stopping being based, at least in part, on the one or more random elements, the at least one cash-spin reel being populated with one or more cash symbol specifying a monetary award amount, and in response to stopping the at least one cash-spin reel,

(i) decrement the number of accrued guaranteed wins; and

(ii) grant an award corresponding to at least one of the displayed cash symbols.

2. The gaming system of claim 1 , wherein prior to decrementing the number of accrued guaranteed wins, in response to the displayed symbol combination not meeting the minimum award threshold, the game-logic circuitry is further configured to:

re-spin and stop the plurality of symbol-bearing reels to display symbol combinations representing an additional free spin outcome based, at least in part, on the one or more random elements; and

grant a corresponding award for each additional free spin outcome until the corresponding displayed symbol combination meets the minimum award threshold.

3. The gaming system of claim 1 , wherein in response to the at least one of the displayed cash symbol specifying a monetary award amount not meeting a predetermined guaranteed minimum award, re-spin and stop the at least one cash-spin reel at an additional cash symbol and determine an additional award corresponding to the additional cash symbol until the additional award meets or exceeds the predetermined guaranteed minimum award.

4. The gaming system of claim 1 , wherein the minimum award threshold is larger than zero and the displayed symbol combination is determined to be a non-losing outcome when the award corresponding to the displayed non-losing outcome meets or exceeds the minimum award threshold.

5. The gaming system of claim 4 , wherein the game-logic circuitry is further configured to determine the minimum award threshold based, at least in part, on the one or more random elements.

6. The gaming system of claim 5 , wherein the minimum award threshold is a positive integer multiple of the wager.

7. The gaming system of claim 1 , wherein the at least one cash-spin reels are simultaneously displayed on the electronic display device, each cash-spin reel spinning and stopping independently.

8. A gaming system primarily dedicated to playing at least one regulated casino wagering game having a base game and a bonus game; the gaming system comprising:

an electronic display device;

one or more electronic input devices configured to detect a physical item associated with a monetary value that establishes a credit balance on the gaming system;

a random element generator configured to generate one or more random elements; and

game-logic circuitry configured to:

initiate the base game in response to an input indicative of a wager drawn on the credit balance;

determine an outcome of the base game based, at least in part, on the one or more random elements;

grant an award in response to the outcome of the base game meeting a predetermined award criterion;

in response to a triggering event, provide the player a first number of free spins and a second number of guaranteed-win plays;

for each of the first number of free spins, rotate a first plurality of symbol-containing reels to a random stop position, the random stop position being determined, at least in part, by the one or more random elements, pay any awards associated with the random stop position, and in response to paying any award associated with the random stop position, decrement the number of guaranteed-win plays; and

in response to at least one guaranteed-win play remaining at the conclusion of the first number of free spins, display the spinning and stopping of at least one cash-spin reel for each of the remaining accrued guaranteed wins, the spinning and stopping being based, at least in part, on the one or more random elements, the at least one cash-spin reel being populated with one or more cash symbols specifying a monetary award amount, and provide a guaranteed award associated with each cash-spin reel spin.
