HazardTrace

Read the clues. Trace a safe path. Solve a short logic field without relying on luck.

This offline deduction game turns hazard finding into a calm, replayable reasoning exercise. Reveal safe cells, interpret the numbers around them, and place markers only when the evidence supports your choice. Empty areas open together so each correct deduction gives you useful momentum.

Choose a field that fits your time:

• Beginner: a 9 x 9 field with 10 hazards
• Intermediate: a 12 x 12 field with 24 hazards
• Advanced: a 16 x 16 field with 40 hazards

Play a fresh random field or work through 60 fixed levels. The chapter path gradually introduces single-cell certainty, remaining counts, cross-clue reasoning, irregular safe areas, and locked safe boundaries. Fixed fields are consistent when reopened, making them useful for learning and replay.

The board gives you the tools needed for a fair challenge: a safe first reveal, automatic expansion through clear areas, visible marker counts, pause, restart, and a review view when a decision goes wrong. Markers can be removed, and a normal reveal never opens a marked cell. Numbers use strong shapes and labels as well as color, so important information stays readable.

Your current field, settings, completion progress, and personal records are kept locally on your device. No account, connection, advertising, purchases, social ranking, or personal data collection is required.
