24 alternatives to Tetris Time
It's almost New Year's and here's an original way to show the countdown using Tetris. I'm sure something similar has been done before, but I had a lot of fun building this (TDD style) using Claude Code. After New Year's it can also function as a regular clock: https://tetris-time.koenvangilst.nl/ For the impatient, it's possible to increase the speed using url parameters: https://tetris-time.koenvangilst.nl/?to=2025-12-31T23:00:00....

Ever heard of the Tetris effect? It’s where you play so much Tetris that the game starts to seep into your thoughts, your dreams, your half-waking hallucinations, and pretty much every part of your reality that has nothing to do with Tetris. Well, I do a lot of crosswords—by “do” I mean both “solve”

Hi HN, I built TetrisBench, a benchmark that tests LLMs on real-time code generation and reasoning through Tetris. Live: https://tetrisbench.com/ *How it works:* Each model starts with an initial optimization function for evaluating Tetris moves. As the game progresses, the model sees the current board state and updates its algorithm—adapting its strategy based on how the game is evolving. The model continuously refines its optimizer: - Board getting too high? Prioritize clearing lines. - Hole forming? Adjust penalties. - Safe stack? Build for a Tetris. The model generates…
