One Ping: Sonar Logic Puzzle

Daily submarine deduction

Free · In‑App Purchases · Designed for iPad. Not verified for macOS.

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.
