Here's some more insights on 10 Chances.
The game has not used a $20K+ car since since January 13, 2015, though it should be self explanatory to not use something other than 1 for the first digit in a guess if there's no 2, and I'm pretty sure they have never put 1 and 2 in the same set of digits when using a <$20K car. They'll typically use a cluster of higher digits to go with the 1 and 0.
The first prize's digit choices almost-always have a 5 (surely so contestants waste a guess on $X5). However, $50 has not been a correct price for the first prize more often than once per season since Season 44. Also, $90 has not been a correct price since March 2015, although 9 is hardly ever a choice.
For the second prize, they have not used anything under $500 (or $510 for that matter) since November 2, 2011, and every playing since Season 43, with only two exceptions (one each in S43 and 44), has had a 5 and/or 9 among the choices, likely to draw non-LFAT contestants into using them as last digits in their guesses.
Here's the breakdown on how 5's and 9's fared for the second prize from Seasons 40-47 (50 playings):
If 5 was a choice...The price was $5X0: 12 times
The price was $X50: 6 times
There was no 5: 12 times
If 9 was a choice...The price was $9X0: 4 times
The price was $X90: 3 times
There was no 9: 6 times
However... Since Season 44, they have since lightened up on dud 5's and 9's. In Season 44, 5 was the dud 3 times and 9 was the dud just once. Since Season 45, 5 and 9 have been a dud only one time each.
If both 5 AND 9 were choices...The price was $950: 2 times
The price was $590: 1 time
The price was $X50: 4 times
The price was $X90: 0 times
The price was $5X0: 0 times
The price was $9X0: 0 times
Additional note: In all Season 42 playings, 9 was never a choice.
In conclusion, should you get to play 10 Chances in the near future...
-
DO NOT GUESS ANYTHING NOT ENDING IN ZERO. (but we know everyone will anyway, and the audience will still chant and cheer with approval for guesses ending in 5 or 9

)
- If 5 is a choice for the second prize, try $5X0 before $X50.
- If both 5 and 9 are choices for the second prize, try $X50 or $950 first. 5 will most definitely be in the price in this scenario.
- Don't guess anything under $510 for the second prize.
- Don't guess anything higher than $19,870 for the car.
