rustoku
High-performance Sudoku solving and generation for Python, powered by a core Rust engine.
Installation
pip install rustoku
Quick Start
import rustoku
# 1. Generate a puzzle
puzzle = rustoku.generate("medium")
print("Generated puzzle:", puzzle)
# 2. Solve a puzzle
solution = rustoku.solve(puzzle)
print("Solved puzzle: ", solution)
# 3. Check solution validity
assert rustoku.check(solution)
# 4. Generate with symmetry and difficulty
symmetric = rustoku.generate_advanced(symmetry="rotational180", difficulty="hard")
# 5. Find all solutions (or check for uniqueness)
solutions = rustoku.solve_all(puzzle)
print(f"Found {len(solutions)} solution(s)")
# 6. Step-by-step human technique solve trace
trace = rustoku.solve_steps(puzzle, difficulty="expert")
print(f"Solved in {len(trace)} steps")
Features
- Blazing Fast: Solves puzzles in microseconds using bitmask constraint tracking and MRV backtracking.
- Human-like Techniques: Explains steps using human solving strategies (Naked/Hidden Singles, Pairs, Triples, Quads, Pointing/Claiming, X-Wing, Swordfish, Jellyfish, Skyscraper, W-Wing, XY-Wing, XYZ-Wing, and AIC).
- Flexible Generation: Generate valid, uniquely solvable Sudoku boards across multiple difficulty levels (
easy,medium,hard,expert) and symmetry modes (rotational180,rotational90,mirrorvertical,mirrorhorizontal,mirrordiagonal).
