About today's four Zeloku boards

Each Zeloku day ships four generated 9×9 Sudoku boards — one Easy, one Medium, one Hard and one Expert. Every published board is checked to have exactly one solution.

The four boards use independent date-based seeds. Difficulty bands currently combine clue targets with an estimated complexity score; they do not guarantee that a particular named technique will appear.

How Zeloku rates difficulty

Clue count alone is an imperfect difficulty proxy, so Zeloku also records an estimated complexity score. Treat the label as a starting point and move up or down based on your own solving experience. The techniques library explains patterns that can help on tougher boards.

If you're stuck, tap Hint. The current hint engine can explain Naked and Hidden Singles; broader technique coverage is still being developed.
