Description
U-Boat Simulator (Demo) is the free test version of the full game U-Boat Simulator.
In this game set in World War 2, you can control a U-Boat VII-C German submarine, search enemy ships and engage in dangerous battles to sink them with torpedoes.
This is not an “arcade” game but a complex and realistic simulator, a bit difficult at the beginning but after a little practice you will enjoy hours and hours of fun.
It has options that you can enable to make the game more realistic and difficult, you can look around your submarine with the 3D views, and so on…

PLEASE VISIT THE WEB SITE AT THIS ADDRESS:
http://www.UBoatSimulator.com
In this web site you will find the instructions for this game, several screenshots and a forum where you can post comments, ideas, report bugs, ask for help or add your stories and screenshots.

Here is a brief explanation:

You can scroll and zoom the map with your fingers, and its limitations are highlighted by yellow lines on the edges.
Your submarine is green, enemies are red, allies are blue and neutral units are black, while the units not yet identified are gray.
The submarine is indicated with a diamond and a cross, warships with a diamond and commercial vessels with a square.

On the top left of the screen there are the indicators with the speed, course and depth.
Clicking on it opens a window to edit them and MOVE THE SUBMARINE.

Always at the top, there are the boxes with the health, the batteries, the oxygen and fuel, the date and time acceleration.
Clicking on the box acceleration is possible to increase the speed of the game.

On the bottom and left there is the map scale.

On the bottom of the screen there are buttons to go on the map, to go to the screen of the charging torpedoes, to bring up the window for launching torpedoes and guidelines, the button to exit the game and on the right the button to put in pause the game.

Clicking on any unit, on the left some usefull informations will appear about its distance, course, speed etc..

The fuel is consumed only browsing on the surface, the batteries and the oxygen staying underwater (they can be recharged at the surface), health decreases when you bang against a ship, when hit by the guns of the enemy ships or near breaks out of depth charges.


This is the free demo version of the game, it contains some limitations, it is better to download it just to have an idea of the game and to test if this game is compatible with your smartphone.

Comments on U-Boat Simulator (Demo) for Android

★★★★★ Tennyson Brown · Aug 17, 2025
As a navy lover that has been begging for a subsim game, this demo is peak, and I have bought the main game now. The torpedo damage is just right and the is slow at the start, but once explosions go off its entertaining as heck. The only problem is that the battery gets used instantly AND THERE'S NO WAY TO RECHARGE IT IN THE DEMO!! Really annoying and game ruining but yeah I bought the main game now so idrc. THE FIGHTER PILOTS CAN SEE A PERISCOPE FROM SO HIGH AND JUST LOCK ONTO ME LIKE WHAT.
★★★★★ Yo when · Feb 18, 2025
The game looks bad though but The explosion and Sinking ships makes me more satisfied
★★★★★ Abbad Rios · Dec 20, 2017
The game is perfect but I am saddened that you cannot repair or replace anything, but I guess that gives me another reason to install the full version right. I did like it though.
★★★★☆ Alexander Duncan · Dec 30, 2020
It's a good game, but you cant put in accurate coordinates for the u - boat.
★☆☆☆☆ Sean Ellis · Nov 23, 2020
It's a nice idea, but it lags like nothing else on my phone. If this is representative of the full game, I can't justify buying it.
★☆☆☆☆ Veena Bijoor · Oct 12, 2021
What game is this I dose'nt understand how to play no boat is I seen so don't waste your time and data very bad game is this I was saying about improve get and improve graphics
