What World Solve is

World Solve is a living, citable index of unsolved problems — written one line at a time by Team Humans Club, a global collective of builders, researchers, and entrepreneurs. We do not solve the problems here. We Democratize Innovation.

For buildersSkip the search for a problem worth your time. Browse a vetted, growing list and start where the gap is real.
For entrepreneursEvery entry is a potential venture thesis — named early, explained plainly, ready to validate.
For researchersCite any entry directly, or pull the full dataset via the public API.

We still haven't proven whether it's possible to always tile a rectangle perfectly using only squares of different, non-repeating sizes.

open Mathematics & Logic

While specific solutions exist for certain rectangles, a full general theory predicting exactly which rectangles allow this kind of tiling remains incomplete. This puzzle blends recreational mathematics with serious combinatorics.
