SOLVE EVERY
VARIANT.
Hybrid Sudoku intelligence for classic, diagonal, hyper, jigsaw, anti-knight, killer, thermometer, arrow, palindrome, renban, whispers and custom constraint schemas. The browser engine combines logical propagation, MRV search, uniqueness analysis and an optional OR-Tools CP-SAT backend adapter.
Universal Sudoku
Solve, analyze, generate and verify Sudoku variants with candidates, reasoning traces, uniqueness scans, custom JSON constraints and responsive background workers.
Built to extend.
The first render is static and deterministic. The local worker engine handles the full interactive workflow, while the included CP-SAT adapter remains optional for server-scale searches.
google/or-tools
OR-Tools CP-SAT-inspired constraint modeling, integer domains, feasibility statuses, solution enumeration and bounded search are reflected in the optional backend adapter.
