Gas Money - Eliminating the wrong prices and trying to leave the right one for last rather than picking the right one at the beginning of the game.
Pocket Change - Giving the first digit of the car for free, and starting the player off with 25 cents pocket change rather than having to guess all 5 digits in the car and having nothing in pocket change to begin. (On a side note, since the contestant eventually ends up picking 4 envelopes off of the board, as a time saver I'd like to see the contestant just pick all 4 off right away to start the game.)
Half Off - Giving a $1,000 bonus for getting all 3 half off items correct.
Time Is Money - The revamped game, while more exciting than the original concept, still makes it very difficult for audience members (both at home and in the studio) to play along with.
Pass The Buck - Going from 8 numbers with 3 "Lose Everything" cards down to 6 numbers and only 2 "Lose Everything" cards, as well as only having to pass the buck twice instead of 3 times during the game, and in doing so earning 1 free pick.
Make Your Move - When they reverted back to the 2-3-4 formula rather than the overlapping digit they did for a brief time.
Hole In One - Adding the second putt although I would amend the rule whereby if a player goofed right away on the pricing portion, and had to putt from the line farthest away from the hole, they only get one chance. To me, they should have to get at least one pricing decision right to earn a second putt.
Dice Game - Going from cars using any digits to digits only appearing on the dice.
Cliff Hangers - For a very brief time when the game began, if I recall correctly, there were 4 small prizes to guess instead of 3. Cutting it down to 3 was much better.
Ten Chances - The unspoken rule of all prices ending in zero.
Lucky Seven - The unspoken rule of no zeroes appearing in the price, although I know they did in the earlier years.
Hi Lo - Having to pick the 3 highest priced products is better than the original version where a player saw the price and had to place it in the Hi or Lo row, and the game continued that way until it was evident that they lost.
Range Game - Increasing the original range from $50 to $150!
Grocery Game - Ditching the $100 bonus if a player quit the game or used up all 5 products before reaching the $6.75 minimum amount required to win.
