## Description

Submarine Hunter Depth Charge is a triangulation-based puzzle game where you command an elite squad to locate and sink hidden submarines. Use buoy tools to measure distances and drag the measuring circles to pinpoint their positions, then fire the depth charge to bring them down.

Campaign features 40 levels that test your logic, arithmetic, and estimation. After level 15, unlock Challenge Mode for high-score battles on Google Play Leaderboards, and master buoy types like sonar, range, and camera to improve your accuracy.

## Review summary

Overall sentiment is mixed to positive. Players praise the core depth-charge puzzle, triangulation lessons, and an ad-free, engaging experience, with many finding it fun and addictive. The educational angle and appealing visuals are common positives. Recurrent criticisms focus on too few levels and a sense of repetition, unclear distance measurements without a ruler tool, and several gameplay bugs (freezes, buoy-drop oscillation, distance-circle glitches). A few reviewers report inconsistent graphics/physics quality. The game is appealing for puzzle/strategy fans, but would benefit from more levels, better measurement tools, and improved stability.

### Pros

- Fun, engaging and challenging gameplay.
- Educational; teaches triangulation/positioning.
- Ad-free experience.
- Good graphics and reflections.
- Unique depth-charge puzzle mechanic (puzzle feel reminiscent of Minesweeper/Battleship).

### Cons

- Not enough levels / too short; requests for more missions.
- Game can become repetitive or boring after initial levels.
- Distance measurement tools and indicators are unclear; lack a ruler tool and UI can mislead.
- Gameplay bugs affecting play (freezes, buoy-drop oscillation, distance-circle glitches).
- Graphics/physics quality is inconsistent across reviews (praising visuals in some reviews, criticized as fake in others).
