Hi
Many option strategies do exist with multiple legs. At the moment any future leg is involved beside the option/s leg/s, we talk about: Synthetic option strategies.
Still: 100% risk free and even with guaranteed low profits is a task hardly non of even what you mentioned on option strategies will fulfill that straight away. A better chances you will have when studying "Back spreads" in all the ways they can be traded. Here you sell option on one side and you buy options on the other side. Various ways can be done with this option strategies.
The whole thing is finally a math thing and best traded and tested with adequate option strategy analyzing software or a very advanced excel sheet who is able to do the work on it.
Now to explain all of this is not what I have time to do so. Nevertheless, there are books who will give you a deeper look into the subject. My first book my mentor put in my hands was this one:

An other one was this:
The Option Trader Handbook: Strategies and Trade Adjustments by George Jabbour (Author), Philip H. Budwick (Author)
and a final one which I also had to read was this one from "
Charles M Cottle: Options Trading: The hidden reality".
The mentioned books are heavy stuff to read, very deep going into the subjects, may take months to understand all in dept and if you are interested in it like I was, I am sure you will take your time to start reading in them. Keep a list of the topics or know all the topics posted in those books and when ever you have questions, you may read this chapter or that chapter and after time it will be in your head and you can start to use it to your advantage the way you want to use that very specific knowledge which is not told in any forum nor in any thread in absolute dept.
Take care and have a nice weekend / Dan
