The reliability of casino software?

How can we determine which online casinos cooperate with trusted slot developers and do not use questionable software with dishonest algorithms?

Previously, I didn't really pay attention to who was developing slot machines, but one day I noticed that slots work strangely in some casinos – bonuses rarely fall out, and winnings are suspicious. After that, I started looking at providers. At Leveling Up Together I immediately saw the list of well-known developers with whom the casino cooperates, and realized that I could trust the platform. There are no questionable games, and the slots work honestly, without unexpected "failures". Now I always check the list of providers before I start playing.
