Original fiction.
Shared curiosity.
El caso de hoy is a collection of original mysteries in Spanish and English. Each case can be solved using the information it contains.
A difficulty for every mood
Easy cases focus on one clear deduction. Medium cases connect several clues. Hard cases require a chain of deductions, without relying on outside knowledge or hidden information.
How the cases are made
We use artificial intelligence to assist with writing, reviewing and developing the website. We check premises and solutions and review each story independently. Characters and events are fictional.
The first collection
The archive includes retrospective practice cases dated 1–28 September 2026. It was created for this launch; the website was not active on those dates. We publish a new daily selection when an edition is ready. Otherwise we say so instead of presenting an old case as new.
