If you want to exercise,
Tetris, greedy snake, gobang are good start.
Actually, for 6 month students on C++ and other programming languages, a snake/tetris game would be still complex.
The real EASIEST and most FASTEST game one could make would be a ping pong game, which is deemed as a traditional "arcade" kind of game like pac man or simple space shooter types.
The types you mentioned take more of an engine structure and such, which must implement the flow through the game, especially a game like tetris.
That's not something I would call "easy", especially for someone fresh to game developing.

You don't need a game engine for tetris or snake. Programming is difficult, but it's definitely possible for someone who has only been learning for a couple of days to make these sort of games.
