Precision Drill

Depth Charge

Ping the wire, read the sonar, triangulate the sector: then land the exact ring before your fuel runs dry.

Fuel reserve
Sink 3 hidden submarines before your darts run out.
How it works
Each sub hides on one of the board's 20 sectors. Ping any number: the ring doesn't matter yet: and sonar tells you how many wedges away you are along the real board wire: COLD (4+), WARM (2–3), HOT (1), or LOCKED (found it). Once locked, the sector's revealed: hit the right ring to detonate: Single for a Patrol Sub, Treble for an Attack Sub, Double for a Command Sub.
Target 1 of 3
Fuel left 24 darts
Sonar armed: throw a search dart anywhere on the board.
Sonar Radar: last ping neighbourhood
Throw your first ping to begin triangulating.
SEARCHING: target hidden somewhere on the wire.

How to Play

Depth Charge: Submarine Hunt turns your darts into sonar. Ping the wire with search darts and read back Cold, Warm or Hot feedback to triangulate which sector a hidden submarine is hiding in, narrowing it down ring by ring. Once you've pinpointed it, you need to land the exact ring to detonate the charge: all before your fuel runs out.

Why It Helps Your Game

This is a pure precision drill dressed up as a puzzle: the sonar feedback loop trains you to read information from each dart and adjust your next throw accordingly, rather than just repeating the same shot. Working under a fuel limit adds real time pressure too, so you're learning to combine deduction with accuracy rather than either skill alone.
