I Made a Math Crossword
The project grafts hexadecimal arithmetic onto a tiled crossword mechanic — you pick squares or shapes that represent a target hex number, with difficulty toggles, a timer, and an on-demand hint (press H). The UI is clean and immediately playable, but the core idea is a clever niche twist rather than a broad innovation; it could use better onboarding, scoring explanation, and shareable hooks to make it stick.
