The trick is to position the rule set in a place where it doesn't fall below the threshold of its too easy to comprehend and doesn't fall above the threshold where its too hard to comprehend, because the brain calls both of those boring. Of course, that range is different for every person and for every different model, because we have different experiences. So a kid starts out and they start learning tic tac toe and they think that it's a game that is worth playing and they are not wrong there are 127,000 possible games of tic tac toe its only you get some more experience and figure out yah but the 127 really kinda boil down to four, right? At a broad level I don't need to know more than that, and suddenly you regard it as trivial. At first its too little its above the line and its noise. Then they understand it then as the experience rises it falls of the bottom and becomes trivial.
