The treasure chests in the Chamber of Fortune were almost certainly reweighed after the first day or two of “Christmas presents”. I’ve had the same experience as each of you - I have gotten the 250-350k chests a few times, and a couple of 75-85 gem chests, but the occasions on which I open 2 - let alone 3 - in a row is less than before. This is over a significant sample, consisting of hundreds of visits to the chamber.
Here’s the interesting part:
As any kid versed in the most basic probability and statistics could tell you, with 3 skulls and 3 rewards in a total of 6 chests, the probability of getting 1 reward is 50%. The probability of getting a second reward is 40% (2 of 5 remaining). The probability of getting a third reward is 25% (1 of 4 remaining).
This is entirely objective. The numbers are: 50%, 40%, 25%. And yet the majority perception of the player base (by far, it seems) is that getting to the 3rd chest is now significantly more difficult; just as the majority perception is that getting there was far easier in the first couple days after the announcement about larger rewards.
So, this begs the question: what is going on behind the scenes that handicaps these base probability values? The algorithm that runs the Chamber is clearly capable of stacking the deck in the player’s - or the House’s - favor. At the very least, the manipulation of these probabilities suggests that the Chamber of Fortune is “dynamic”; or in other words, the placement of skulls and rewards changes (and the values of those rewards may change) with every chest that is opened. How it’s done (e.g. senses touches on phones/tablets, mouse position on PC, etc, sorts based off previous choices the player has made) is the question.
