Slay the Spire 2 patch fixes RNG after player proof

Mega Crit has released the second major update for Slay the Spire 2 to the main Steam branch, calling it "4 patches in 1." Alongside changes beta branch players are already familiar with, the studio says the update also has "big changes that will be totally new for everyone." A dedicated fan, Tckmn, spent an eight-hour stream and wrote a 6,600-word essay arguing the game's randomness was rigged.

Their argument was that "knowing the first output of one of the game's RNGs gives information that helps predict the first output of all of the others." Mega Crit admitted that "we did, in fact, have some unusual RNG problems" and gave a "Huge shoutout to Tckmn for doing the research - their eight-hour descent into madness was an entertaining watch, and we wouldn't have caught the issue without it." The studio explained how run seeds had accidentally "allowed players to predict outcomes given knowledge of unrelated parts of the game," and said an RNG rework was necessary to prevent players prioritizing pattern memorization.
