Signals

Click cells to reveal resources hidden in the grid. Every find adds to your score.

Numbers indicate how many hazards are in the 9 that surround the cell.
Use these to navigate the grid safely.

The cell highlighted yellow has 3 surrounding hazards. 2 are already shown so the square directly above must contain a hazard.

Use flags to mark cells where you suspect a hazard. The lower bar has a hazard count and a button to turn flag mode off/on. Right-clicking also adds a flag.

You have 5 health points. Hitting a hazard costs 1 point.
