I only can open about 1/5 brown chests anyways, which blows and makes me think there most be some other way to open them.
1/5 seems rather low, generally I can at least hit ~2/3, including caskets with only 5 attempts.
There are 6 possible hints:
1. First digit is Even/Odd. (Cuts possible choices to a pool of 50 max)
2. Second digit is Even/Odd. (Cuts possible choices to a pool of 45 max)
3. First digit is [3 Numbers]. (Cuts possible answers to a pool of 30 max)
4. Second digit is [3 Numbers]. (Cuts possible answers to a pool of 27 max)
5. One of the digits is [X]. (Cuts possible answers to a pool of 18 max)
6. The correct number is between [X] and [Y]. (Cuts possible answers to w/e range given)
Even on a 5 attempt box, getting the least useful clue, and then just guessing at a the halway point, you should still should be seeing better results than 1/5.
One of the numbers is a 3
The first number is odd
The first number is a 2,3,4
The combination is less then 39
1 attempt left...
The number was 35!
Not assuming that you actually played out that scenario, but in this specific situation, it's played out very incorrectly, it's almost always a bad idea to take more than two hints, especially with a five-guess box. The first clue by itself eliminates around 80% of the guesses. From that clue alone, the worst possible chance you have at opening the box should be 1/2, on a good second clue, you might even be able to bump it to 100%. Now in the example given, the second clue is largely useless (the worst possible clue in that situation
), and that of course can happen. It's just a matter of knowing what possible choices you have left, and the guess most likely to remove the most answers.
Personally, I almost always stop at 2 hints, very rarely 3. I get a pretty good success rate going with that. Edited, Jul 20th 2011 7:15pm by KodoReturns
