## Description

One board a day. Read the sonar digits, deduce where the contacts hide, and fire a clean solution. Sink the flagship every tenth mission.

You are the sonar operator. Somewhere under the grid, silent contacts are hiding.

Every digit on the board is a hydrophone: it reports the exact distance to the NEAREST contact — counted in cells, no diagonals. Cross-reference the readings, rule out impossible waters, and place your fixes. When every sensor confirms, fire the solution and watch the torpedoes run.

ONE PING A DAY
A single daily patrol, the same board for everyone. Keep your streak alive and see how deep your run takes you — and how you rank against every other operator who dived today.

PATROL I — THE CAMPAIGN
150 hand-verified missions across three depth zones: the Shallows, the Trench and the Abyss. Two to five contacts per board, a rhythm that keeps you guessing, and every tenth mission a FLAGSHIP hunt on a big 8×8 grid — five bearings, one implosion you will not forget. One purchase, no ads, yours forever.

PURE DEDUCTION
Every board has exactly one solution and never needs guessing. Fewer moves, better rank: a clean fix with no wasted marks is the mark of a true operator.

Dive. Listen. Deduce. One ping only.
