PuzzleTide Sudoku

Generate, solve, and validate sudoku with the local PuzzleTide CLI.

Never generate or solve a sudoku by hand. Hand-made puzzles usually have multiple solutions or none; hand-solving is slow and error-prone. The CLI verifies every generated puzzle has exactly one solution, and its solver is instant.

Prefer the local CLI. Check availability in this order:

ptide --version
puzzletide --version
npx puzzletide --version

If none of those work, ask the user before installing (npm install -g puzzletide).
