I'm a huge fan of Tetris and have played them all. I think this version is the best one. Not only because of the drama behind it, but two player mode is actually pretty fun.<p><a href="https://tetris.wiki/Tetris_(NES,_Tengen)" rel="nofollow">https://tetris.wiki/Tetris_(NES,_Tengen)</a>

I was expecting something like DQN, but what I actually saw was a new approach, so it was fascinating. Usually when you're making small AI demos and doing hands-on exercises, you work with Tetris a lot.<p>In NES Tetris, if the input is the same, the result is the same, so you can store all the inputs and reproduce specific moments. The state becomes like a graph, which allows for fuzzing testing. It's interesting

    Seems to be influenced by the pieces on the board. Bill talks about it a little in the article. You do seem to get more | shaped pieces when you leave those spaces open on the board.

    You're talking about piece, right? I know that it's actually determined by the execution state per frame and the button inputs [1]. I looked into Tetris AI before because I found it fascinating, but I might be mistaken.<p>[1]<a href="https://tetrissuomi.wordpress.com/wp-content/uploads/2020/04/nes_tetris_rng.pdf" rel="nofollow">https://tetrissuomi.wordpress.com/wp-content/uploads/2020/04...</a>
