Holmio turns the periodic table into a daily detective game
Each day brings a new case with 118 suspects, the chemical elements, and six accusations to find the culprit; according to its author, no registration is required.
Holmio is a daily deduction game, in the style of Wordle but with a noir setting, for reviewing the elements of the periodic table. You read the case report, accuse an element and, if you are wrong, choose a clue to keep investigating. You have six accusations to find the culprit.
Besides the case of the day, the website offers an archive for playing earlier cases and free practice with a random element that does not count towards the archive. It has light and dark modes and lets you share your result as an image.
It was presented in Vibe Coding Educativo by Dani García, who explains that he made it with Claude Code in HTML, CSS and JavaScript, with no frameworks or server of its own, and publishes it on GitHub Pages; the website is signed by El profe de la bata. According to its author, the most work went into the content: a case for each of the 118 elements with data checked against sources. He asks users to tell him about bugs or ideas for the classroom. Another activity by El profe de la bata, on the gravitational field, has already appeared in the paper.
