Just a word of warning, the Tetris Company is pretty aggressive about protecting their trademarks. I'd at least pick a different name, but sometimes they even go after Tetris clones which don't use the name (e.g. Apotris). https://github.com/github/dmca/blob/adcac3eddac2e5555d87942d...
It is good but not intuitive. Also the line doesn’t clear when all tiles in the row are filled. It is good to show the shadow of the piece where it would fall - at least as an option.
You gotta press “clear” to Clear the rows And you can click the “ghost” icon to get the shadow piece. You’re absolutely right, not intuitive

Which is crazy, because the shapes are just an idea, and you can't copyright ideas. They also couldn't be a trademark infringement (IANAL, though) if you don't use them in your branding.
> you can't copyright ideas They can go after you for anything. Whether or not that would hold in court is a separate question, but they count on the fact that you would be probably unwilling to test it.

Not just 'Tetris' (and *-'tris') trademark and Lanham Act trade dress, but they have also successfully argued in court [1] that the 'look and feel' of Tetris constitutes its copyrighted expression. In that case, Tetris Holding argued (and the judge agreed) that even the use of the seven one-sided tetromino playing pieces was part of their copyright. Here's the description of the only Tetris gameplay mechanics the jud…
Disclaimer: I chose the colors from first principles and drew the graphics for Xio's version from scratch in Photoshop without any reference (as a volunteer; it was my friends' company), had to sit through depositions about this, etc. In theory the Tetris Company is incorrect on the merits (the features they claim as "trade dress" are clear aspects of the game rules, not ornamentation, and in Xio's game had quite not…
What surprised me most from the ruling was how it took the legal doctrine of idea-expression dichotomy and twisted it into absurdity, hinging on an implicit argument that a game design essentially serves no utilitarian 'function' or 'purpose'. Core mechanics or essential gameplay rules like the tetrominoes or the 10-block width of the playfield are thus marked 'expression' or 'arbitrary flourishes', leaving a vague, unidentifiable abstraction of a falling-blocks puzzle game as the only unprotectible set of game rules that form its 'idea'.
Xio was free to design a puzzle game without tetrominoes, or downward+lateral+rotating movements, or a 10x20 playfield, and it would still 'function' just as well (that is: not at all, it's just a game). A chess game developer is equally free to design a strategy game without an 8x8 board or the knight's distinctive L-shaped movement, but it would no longer be chess, it would be rules for a completely different game.

Thank you all for playing and leaving such great suggestions and comments!! I will likely add many of these suggestions over the weekend. - Multi bag instead of fully random - No auto clear on game end - Clear hold on game reset - Rename to LAZY PUBLIC DOMAIN BLOCK GAME also, I need better UX or something, because some of the suggestions are already implemented but it’s prob not initiative/ hard to find. Clicking on…
While we are at unconventional tetris implementations: I wrote a cosmopolitan libc based tetris clone for Braille display users. IOW, pieces "fall" horizontally, and blocks are rendered with (unicode) braille. https://github.com/mlang/betris Big thanks to @jart, cosmo is a godsent for cross-platform TUI stuff.
