Ah well, it’s still fun and it does appear to measure how good AI is in creating these kind of games.
The link was broken indeed. Should be fixed now. Glad you like it!
The one I shared in the parent is for the New Year's countdown: https://tetris-time.koenvangilst.nl/?mode=countdown&to=2026-...
The basic link should show the current time, even at high speeds: https://tetris-time.koenvangilst.nl/?speed=10
Oh wait, I just tested it on a higher speed (20) and I see what you mean. It's drawing over the existing Tetrominoes! I'm going to max the speed at 10.
What worked particularly well here was a test-driven (TDD) approach. I asked Claude Code to focus only on the algorithm for selecting the next Tetromino (the Tetris blocks), starting with tests. After that, things went smoothly, though it still took many follow-up prompts (around 100) to reach the final result.
- You can play the Claude game here (note: doesn't work on Safari for some reason): https://html-preview.github.io/?url=https://raw.githubuserco...
- o3-mini's version is here: https://html-preview.github.io/?url=https://raw.githubuserco...

I've now corrected the experiment to accurately take the image into account. This meant that Deepseek was no longer able to find all the sets, but o3-mini still did a good job.
Though this game is a solved computer problem — easily tackled by algorithms or deep learning — I thought it would be interesting to see if Large Language Models (LLMs) could figure it out.
According the the Wageningen University report there is! It's small road, highways but also rail road tracks. The actual report can be found here: https://research.wur.nl/en/publications/landelijk-grondgebru...
This also contains the definitions of land use categories. I've grouped all of the above (roads, rail, highways) under infrastructure.
