I can't visualize a tetris block, much less a whole tetris game. I think I could draw all the tetris blocks if I tried so the information is there, just not stored as jpg. More like a zipped text file.
Yeah I have the same thing. I can sort of visualize the concept, like foggy still images of tetris games I've played but I cannot imagine a game setup where a piece would fall and complete a line. That is too specific. I can just do like general concepts, not specifics.
Since learning about this, I have decided to keep the game installed on my phone in case something wild happens (I'm thinking after witnessing an accident or something). It is sort of comforting to have a scientifically backed up mental strategy that is easily accessible, even if it's not a lot. I gather that tetris keeps the part of your brain responsible for looping images occupied with, well, tetris.
