Math puzzle meets rolling-ball navigation with adaptive performance for older phones.
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.
Wordle-for-math with rare-solution hunting, but Nerdle and Countdown already solved this.
Clever tessellation math puzzles—hexagon and triangle variants add genuine cognitive depth.
Math-hard puzzle game auto-generates thousands of levels from group theory.
Clean Flash Anzan implementation but mental math games are well-established.
