Someone first implemented something like this and shared it on HN https://news.ycombinator.com/item?id=44103839

...and I love it :D

Unfortunately, they removed it later (no idea why). So I decided to make my own implementation.

Key features: - The pieces are selected at random, unlike the true Tetris, which uses Multi bag sampling. VERY interesting dynamic. Try it! - The pieces don't fall on their own. They await my instruction - The line clears when I decide it's time for it to clear :D

Enjoy ;-)
