Allow me to answer some questions you guys may have.
* Yes, it does sound like I combined 3 different game concepts (though in some cases, some slight elements of Rat Race and Time is Money were also integrated if you look carefully
) into one new game, but only because I liked the idea of using multiple game elements to make a game.
* The element of risk involves that, if the contestant continues going forward after making one mistake; let's say, the contestant lost half of their $10k, won another chance, and made another mistake, they would keep losing their money until they have no more chances. From the moment that they won their last chance (say, start from $10,000, down to $5k, to $2.5k, to $1,250 at last), if they mess up at that point, they lose it all. For each layer they guess correctly, they win $10,000 more to their total. If they make a mistake, and win a second chance, the game continues, but they don't get the $10k for that layer if they win a second chance. ($10k becomes $5k, win second chance to next layer, gets next grocery item correct, win $10k for a total of $15k and so on) So, if to say, the contestant made 4 correct guesses to win $40,000, and they messed up on the last layer/grocery item, they would lose $20,000, but would still have another chance to win the car and the remainder of their bank, so long as they do not mess up on the last medium prize (which means that it is possible to lose everything on the last layer - or any layer in the game - by getting all three of the medium prizes' prices wrong). The all-or-nothing risk is there, but it depends on how you look at it. That being said, however, there are no guranteed sums. Just like "It's In The Bag," a contestant can take the money they have up to the point they reached, or they can risk losing half their bank to correctly identify the correct price of a grocery item in the layers, or they can risk it all trying to win another chance to continue the game.
* I do admit that a cash prize of $50,000 ($10,000 a level for each correct guess on the grocery items) does sound rather big for a car game, whether the car is less than $20,000, or even greater than $100,000! However, the only reason why I suggested that big of a cash prize is to accommodate the factor of inflation. If this were Big Money Week (or the Million Dollar Spectaculars, which I wish we could have again), then, I would double the ante of the cash prize to $100,000. That being said, however, given that there is a large cash prize as a bonus, this game would do best with cars that make the $50,000 worth going for (I can't necessarily give an exact amount, unfortunately).
* With all that in mind, on a slightly lighter note, the reason why I suggested this would be a car game for both a car and cash is partly due to the game's name about finding oil to power cars with internal combustion engines (although my direct inspiration about it is slightly related to politics, so I won't go into that topic here).
