About this game

Read the clues. Mark the hazards. Find a safe path.

This offline logic game turns each field into a short, focused deduction session. Choose a Beginner, Intermediate, or Advanced field, then use the numbers around revealed cells to separate safe ground from hidden hazards.

Clear controls keep every decision understandable:
• Reveal cells with a tap.
• Cycle flags and question marks in Mark mode, or long press a cell.
• Let empty safe areas expand automatically.
• Pause the clock, undo a recent marker by clearing it, or restart a field when you want a fresh line of reasoning.

Every first move is protected, and fixed fields use repeatable layouts. The guide explains single-cell certainty, remaining hazard counts, and crossing clues so you can solve with evidence instead of relying on blind guesses.

Choose from progressive fixed chapters, a local daily field, or a new random field. On a mistake, the field pauses for review so you can inspect the trigger and nearby clues before trying again. Completed fields show your time and keep local progress.

No account, connection, advertising, camera, microphone, or location access is needed. Your current field, preferences, and progress remain on your device.
