There's a way to not lose in roulette, right? :)

I know many ways to "not lose" in roulette, but none of them are correct... :D Roulette is a game with a negative expected value and, by definition, is a losing game. Of course, you can bet on the same number three times and guess correctly, but that's probability theory, not a system. All systems are doomed to fail. You can't guarantee a win in roulette; you can only have a positive balance for some time with a certain probability. The more you play, the less chance you have of winning in the end. Ideally, if you're in the plus, you should stop. But it doesn't work out that way... :)

From the arrangement of monsters in a certain order and certain moves during the battle itself. For example, if I place a monster on "this" cell, morale will trigger, but if "here," it won't...

Yes, that's what's called "pseudo-random." That is, there are certain criteria, the combination of which determines the "randomness" in the occurrence of morale or spells that have a probabilistic nature. But they vary from battle to battle and cannot be considered a law. After all, there is a law that determines the trajectory of a body thrown at an angle to the horizon... Now, using it, try to throw a basketball into the hoop several times in a row from different points on the court... :) The law exists, but its operation depends on many factors that cannot be taken into account. That's why we say it's random.
