ONE RULE SIMPLIFIED!!!! :3
If you've 3 or more of the same shapes (numbers)! And your opponent is less..for example he has two : ll ll and the other are different numbers and you've three: ll ll ll and the other are different..You would win! Because you've three numbers are the same and he is less! And so on..This is one side of it! There is also the value of the numbers, if you've a mix of numbers there are rules for certain sets! Well, long ones too! You'd read them somewhere idk maybe in the manuals of the games!
edit: I quoted this from witcher-wiki for you since I fail at explaining lol

- Five-high straight – dice showing I, II, III, IV and V
