## What is Submarine Hunter Depth Charge?

Take command of Depth Charge, an elite squad of submarine hunters.
Use a variety of tools to discover the location of the hidden submarines and destroy them.

HOW TO PLAY
• This is a game of logic, arithmetic, estimation and triangulation.
• Drop buoys in the ocean water
• The buoys tell you how far they are from the submarine
• Estimate how far that distance is from the buoy
• Drag the measuring circle of each buoy to match the distance
• The enemy submarine should be at the location where the measuring circles intersect
• Fire a depth charge from your warship at that location
• If you've estimated correctly the enemy attack submarine will sink
• Find and eliminate all the submarines in the level

CAMPAIGN
The first level will familiarize you with the basics.
After that there's an additional 39 levels for you to solve.
Only the smartest will be able to get a three star score on all the levels.

CHALLENGE MODE
Play for a highscore on the Game Center Leaderboards.
Should only be attempted by experienced players,
that's why this mode only unlocks after completing level 15 of the campaign.


Tools available to find and destroy submarines:

• SONAR BUOY
The standard tool for detecting submarines
• RANGE BUOY
Automatically places the measuring circle at the exact position
No need to drag it manually
• CAMERA BUOY
Equipped with the U96 underwater camera.
If the submarine is in viewing range it will show exactly where it is.

• DEPTH CHARGE
The standard submarine eliminating tool
• TRIPLE CHARGE
Three charges dropped in a triangular shape for maximum coverage, carpet bombing.
• HOMING CHARGE
When in range, always a direct hit!

### 1/5 — Dumb! Text too small numbnuts.

*2025-09-27, version 1.0.4*

You have to keep stepping through the same, meaningless banter. Flawed design. Good for non-thinkers. Text too small to read! LOL

### 2/5 — Dumb!

### 5/5 — Tactical & Intuitive Harpoonish Challenge

*2019-11-06, version 1.0.4*

This scratches that itch. Hard to define what game playing desires I have but so few of the games in the iPhone match it. If ya think you might have salt water & a protractor in your family crest - this is super satisfying. Congrats to the coder!

### 5/5 — Great game!!

*2019-10-27, version 1.0.4*

I love the mechanics of the game and how you need to think quick with subs that are moving!

### 3/5 — NEEDS MORE LEVELS!!!

*2019-07-08*

Ok game but definitely needs more levels with greater equipment & challenges. Has great potential.

### 5/5 — Sub

*2019-03-13, version 1.0.4*

It’s a good and underrated game wish they would make more levels like it.

### 5/5 — Fun!

*2018-09-07, version 1.0.4*

This is my favorite game for pooping.

### 3/5 — Won’t start

*2017-11-15, version 1.0.3*

This is a great game that simulates aspects of ASW.

I used to be able to play this game on my iPhone 5s but as of yesterday the game won’t start. I’m using an iPhone 5S and running iOS 11.1.1 . Any help would be appreciated as I love this game, thanks.
