Learn Through Logic
Hints don’t solve the puzzle — they explain it.
• Conflict check
• Box-line interaction
• Naked singles
• Optional cell reveal (with warning)
Advanced techniques are intentionally left to the player.
The goal is learning, not skipping.
Zendoku is a thinking companion — closer to paper Sudoku than a typical mobile game.
