Sometimes when you create a class you can add there several properties (new data members) that you are not certain if you want to do or not. For example, I have a casino slots game. I have tiles and tiles are spinning on different reels. So once 3 tiles come on the same line then player wins 3$, 4 tiles - 4$ and 5 tiles - 5$ for tile
A and for tile
B player wins 5$, 10$, 20$ accordingly. Should, for example, each tile store the data of its reward or there should be a reward manager for checking how many tiles are consecutive next to each other to give the reward to the player?
Please note that I don't want to have such a situation. But I find me many times thinking "Should I add this data, and consequently, corresponding logic the my class or not?". I worry about single responsibility principle when I want to have different managers for such things, but on the other hand I came to a situation to create several singletons or singleton-like classes.
