:tetris:📄 You can now play Tetris in a PDF File.

[Thomas Rinsma], a security analyst and hobbyist tinkerer, recently figured out how to create a version of Tetris that runs inside a PDF file. He tackled the project “just for fun” after learning the potential implementations of PDF’s JavaScript API. The result is a novel version [Rinsma] calls PDFTRIS.

There’s a global community dedicated to finding new ways to challenge themselves in Tetris, from speedruning the classic puzzler to technically “beating” it. But the latest feat isn’t a newly discovered hidden glitch or high score — it’s an entirely new way to play the game.

[Rinsma] explained that it’s already “relatively well-known” that PDFs can support a number of features such as dynamic content scripting when opened in something like Adobe Acrobat/Reader. Some of that same scripting support, however, is also available in both Mozilla Firefox and Google Chromium’s respective PDF readers, PDF.js and PDFium.

The PDF containing a 10×20 grid of field buttons. These alternate between shaded and empty blocks depending on the JavaScript input, allowing a player to use preprogrammed keyboard instructions to move and shift the tetronimoes — the official term for four-block shapes such as those in Tetris blocks.

“It was a bit tricky to find a union of features that work in both engines, but in the end it turns out that showing/hiding annotation ‘fields’ works well to make monochrome pixels, and keyboard input can be achieved by typing in a text input box,” [Rinsma] wrote in a post.

Thomas Rinsma decided to abuse PDF field objects to render monochrome grid, and combine it with keystroke-entry in a text field to receive inputs – that’s how #PDFTris, a playable Tetris in a PDF file was born.
