A-Puzzle-A-Day Solver

A solver of DragonFjord's A-Puzzle-A-Day and similar puzzle(s) like this one with tetrominoes.

The web version of this tool is available here.

The solver's algorithm is implemented in Rust and its code is compiled to WebAssembly to run on browsers. Algorithm details are documented in SOLVER_ALGORITHM.md.

Note that this is my personal hobby project and has nothing to do with the authors of the puzzles or my employer.
