Play Deep Sonar — No-Guess Mine Puzzle

Hints cost 10 coins

Deep Sonar is a mine deduction puzzle where every board can be cleared by logic alone. Each number counts the mines inside its sonar shape: a ring of eight neighbours, a cross, or a diagonal. Flag the mines, clear every safe cell, and use the edge totals on later boards. Sixty boards run across five tiers, with a daily board and hints that explain each step.
