What are some good project ideas to learn OOP?

Hi Ismael!

I found these online(specifically for c#):

Other than those, I would suggest trying to emulate a familiar real-world object or a game of some sort.

One popular (and rather challenging) game coding challenge is The Simon Game:

Which I usually see as a JavaScriptm HTML and CSS challenge, but I'm sure a C# version would be interesting, too.

This my quirky version of The Simon Game coding challenge (using React and Redux):

I also made my own project - a game using Python to essentially explore "The Monty Hall Problem":

My game allowed a user to play the game manually or several times in a row (100, 100, 10,000, or even 100,000) both staying every and switching every time, so you can really see the likelihood of winning or losing in each case. (You are definitely twice as likely to win if you switch every time instead of staying!?!)

I hope that helps.

Stay safe and happy coding!
