My question on How to Gain Programs Building Experience Beyond Basic Grammar and Formatting.

Hello fellow quest mates. My question of the day is as follows: I have previewed c++ in the most shallow sense over the winter break, meaning I just know the basic concepts, grammar, and formatting. But say I want to build a mini game for my own entertainment. How should I lay out my plans for the game and utilize the programming language to actually build it? In another words, I know the basic pieces of the Lego blocks, now how should I start practising my skills in coming up with a schema or a blueprint to actually build a building based on what I learned about the Lego blocks? To me, in order to better motivate oneself to learn something, it's best if I can actually build something useful or entertaining using what I just learned, otherwise it would be tedious, as concepts and grammar are mere meaningless strings without knowing their application.
