I used to be really against the hint systems, until I was able to learn its algorithms and decision-making processes and used that advantage to trap people. All the way to 10th Dan.

I noticed as much when I played against you. At first I was stunned. "10th Dan? Who reaches that? Either a mastermind, a bot or..." And then I realized in horror that the most likely alternative was "someone who knows how to exploit the bot and suji-trap people."

To anyone interested in knowing what the hint system prioritizes, here are some writings I found. Credit to Sirocco (the person I'm replying to) herself.

The hint system does not simply follow a pure probability approach, but with a priority system. My speculation of the priority is: Nomi tenpai < Yakuhai < Pinfu < Tanyao < Sanshoku Doujun < Toitoi < Chiitoi < Chanta < Honitsu < everything else, even if there is only 1 tile left to complete such Yaku. It appears to disregard anything else besides the aforementioned Yaku. On several occasions it told me to discard my slightly less advantageous Yaku dora pons, discard my tenpai Suuankou, discard my Iishanten Kokushi Musou. It also disapproves of Jigoku even though in many occasions the Jigoku tanki wait would work and have worked extremely well.

The dangerous tiles indicating system strictly follows a "live tiles/furiten/suji" code. It (...) Gives advantages to veterans who know how to exploit it when they know their opponents are blindly following the hints. By committing kanchan/penchan/jigoku tanki/suji trap, they easily trick such players to deal into their hands.

Since you mentioned kanchan, can I assume that the bot won't consider if something is a riichi tile or not when doing the danger tile calculation when human players normally would (i.e. to allow ryankan)?
