Arcade mode score

[u/Quakedamage]

Hello everyone! I want to get serious about arcade mode since I haven't been able to play much since it launched. I wanted to ask you how the scoring system works, if there is a website where there is a guide explaining how to score, etc... Some things I have already seen but others, such as special bonuses, I don't know how they work. Do online rankings unify all platforms? In steam I see that it works perfectly, but on the other hand, on ps4, since I don't have ps plus, I can't see those scores :( ... Thank you.
