How to play Craftsman online with a friend on Android

Modern mobile devices have turned into full-fledged gaming consoles, allowing you to enjoy complex sandboxes anywhere in the world. The game Craftsman: Building Craft was no exception, offering users features similar to its legendary counterparts, but with a unique style. Many players are faced with the desire to join forces with friends to build grandiose projects or survive together, but the process of setting up a local network often raises questions among beginners. Understanding the basic principles of operation local Wi-Fi connection is the key to a successful session without delays and interruptions.

Unlike server solutions with a dedicated IP address, the mobile version often relies on a direct connection between devices on the same local network. This means that the quality of the connection directly depends on the stability of your router and the distance to it. Before starting the game, you need to make sure that both smartphones are in the same network conditions. Both devices must be connected to the same Wi-Fi network with a frequency of 2.4 GHz or 5 GHz, use mobile data (4G/5G) for local host is impossible without special emulators. Ignoring this fundamental rule results in the server simply not being displayed in the list of available worlds.

The process of creating a multi-player world requires attention to privacy settings and connection ports. If you plan to spend time in a company, you will need to choose the right hosting mode that will allow incoming connections to pass through the Android system firewall. In some cases, system restrictions may block server detection, so it is important to check the application permissions in your operating system settings. Next, we will analyze in detail each step necessary to organize a stable game.

Technical requirements and network preparation

Before moving on to setting up the gameplay, you should evaluate the capabilities of your equipment. Mobile sandbox games require significant CPU resources, especially when rendering to multiple players simultaneously. A weak Wi-Fi module or outdated communication standard can become a (bottleneck) of the entire system. It is recommended to use routers that support standard 802.11ac or later, as they provide better throughput.

Connection stability is a critical factor. If one of the participants has an unstable signal, this can lead to blocks being desynchronized and all participants crashing out of the game. Often the problem lies in range congestion, especially if you live in an apartment building where dozens of neighboring networks create interference. Switching to a less crowded channel or using the 5 GHz band can dramatically improve the situation.

• 📶 Make sure both smartphones are connected to the same router and not to different access points (a guest network can isolate devices).
• 🔋 Charge your device batteries to at least 50%, as active network communication quickly drains energy.
• 📱 Close background applications that consume traffic (torrents, downloads, streaming) to free up the channel.
• 🛡️ Check that your antivirus or router settings do not block local connections (AP Isolation).

⚠️ Attention: Some public Wi-Fi networks (in cafes, shopping centers, educational institutions) have built-in client isolation. In such networks, devices cannot see each other, and playing over a local network will be impossible, even if the Internet is working.

It is also worth considering that the Android operating system can aggressively save energy by turning off the Wi-Fi module in the background or limiting the operation of applications. For uninterrupted gaming, you need to add Craftsman battery optimization to the exclusion list. This ensures that the system will not interrupt the network connection if you minimize the game or the screen goes dark for a short time.

Creating a server and setting up the world

Organizing the gameplay begins with choosing a device that will act as a host. The host is the smartphone on which the world is running and which broadcasts its state to other players. It is on this device that the world is created, and it is its performance that determines the quality of graphics and drawing distance for all participants. Choose a phone with a more powerful processor and more RAM for this role.

Once you launch the application, go to the main menu and select the option to create a new world or load an existing one. In the world settings (often available before launch or through the settings button in the world selection menu), you must activate the multiplayer game mode. Look for the switch with the name "Multiplayer","Play with Friends" or the Wi-Fi icon. Without activating this option, the world will remain visible only to the owner.

After activating the multiplayer mode, the world will begin to load. At this point, the system creates a local server that listens for connections. Firewall notifications may appear on your screen asking for permission to access the network—be sure to select Allow or Allow. If you skip this step, the operating system will block incoming connections and friends will not be able to enter the game.

It is important to note that some versions of the game have a limit on the number of simultaneous players. Typically, mobile sandboxes support from 4 to 8 people in one session, but this depends on the specific build Craftsman. If you are planning a game with a large group, make sure that your router tariff plan and the power of the host device will allow you to process this amount of data without lags.

Connecting a second player

The second player (client) must perform a series of actions to detect the running world. While in the main menu of the game, you need to go to the section responsible for the network game. Usually this is a button Play or Multiplayer. After going to this section, the game will automatically begin scanning the local network in search of available servers.

If the setting is correct, after a few seconds the name of the world created by the host will appear in the list. It can be the same as the name of the world or the name of the creator's device. To connect, just click on the server name. If the world is password protected (optional setting), the system will ask you to enter a passphrase, which must be provided by the host.

• 🔍 If the server is not found, try refreshing the list by clicking the refresh button or the crossed out arrow.
• 📝 Make sure that the game versions on both devices are exactly the same (check the version number in the settings).
• 📵 Disable VPN on both devices, as they can change the virtual location and interfere with local discovery.
• 🔄 Restart the game on both smartphones if the search does not produce results within a minute.

During the connection process, a situation may arise where the server is visible, but the connection is reset immediately after the login attempt. This often indicates incompatible versions of resource files or modifications. If you used any addons or skins, make sure they are installed on all devices participating in the session. Otherwise, the game may block the input to prevent texture errors.

What to do if device names are not visible?

If automatic search does not work, some versions of the game allow you to connect manually by IP address. To do this, the host must find out its local IP (for example, 192.168.1.5) in the Android Wi-Fi settings and enter it in the "Add Server" field on the friend's device. However, in mobile Craftsman this feature may be hidden or absent, relying solely on automatic discovery (UPnP).

Solving connection problems

Despite its apparent simplicity, LAN technologies often encounter software conflicts. One of the most common problems is when devices “see” the router, but do not see each other. This is a classic symptom of the enabled feature AP Isolation (access point isolation) on the router. This feature is intended for security in public places, but it makes it impossible to directly exchange data between smartphones on a home network.

Another common cause of failures is antivirus software. Built-in defenders or third-party applications may classify a game's attempt to create a server as a potentially dangerous activity. In this case, you need to temporarily disable network protection or add the game to the white list of trusted applications. It’s also worth checking if your phone is in “Data Saver” mode, which may limit background network activity.

Problem	Probable cause	Solution
Server not found	Various Wi-Fi networks or AP Isolation	Check the name of the network, go to the router settings
Crash when connecting	Game version mismatch	Update the application in Google Play on both devices
Lags and teleportation	Weak signal or low speed	Move closer to the router, turn off downloads
Black screen from a friend	Error in textures or addons	Delete mods, reinstall game

If you are using a dual-band router, make sure that both phones are connected to exactly the same frequency. Although modern routers often combine 2.4 GHz and 5 GHz under one name (Smart Connect), this sometimes causes problems with device visibility. In this case, it makes sense to temporarily separate the networks in the router settings or force both devices to connect to one specific frequency through the Wi-Fi settings on the phone.

Optimizing performance for multiplayer

Playing over the network creates additional load on the processor, since the device must not only render the image, but also constantly synchronize the position of players, the state of blocks and mobs. On mid-range and budget smartphones, this can lead to a drop in FPS. To improve the situation, it is recommended to lower the graphics settings within the game. Reducing rendering distance (Render Distance) will significantly reduce the load.

It is also worth disabling beautiful but resource-intensive effects such as dynamic lighting, shadows and anti-aliasing. In multiplayer mode, the visuals often take a backseat to the fluidity of the controls. If the game still slows down, try closing all other applications and clearing the RAM before starting.

• 📉 Reduce the "Render Distance" value to 8-10 chunks.
• 🌫️ Disable the "Fancy Graphics" or "Beautiful Skies" option.
• 🔇 Turning off music and reducing the quality of sounds can free up CPU resources a little.
• 📱 Use the "Game Mode" in the smartphone shell, if it has one, to prioritize processes.

If the host begins to experience difficulties processing data, all connected players will lag, even if they have powerful telephones. Therefore, it is always better to choose a more powerful device as a host, even if its screen is smaller.

Frequently asked questions (FAQ)

Is it possible to play Craftsman via mobile data (4G/5G) without Wi-Fi?

This cannot be done using standard game tools, since the local network function requires being on the same LAN network. However, there are workarounds: creating a virtual local network (VPN) on one of the devices (for example, through the NetBridge application or similar), to which the second player will connect. But this method is difficult to set up and requires root access or special permissions.

Why does my friend see my world, but cannot connect to it?

Most likely, the problem is with a firewall or antivirus that is blocking the incoming connection. Also check to see if the world has a password that your friend doesn't know about. In rare cases, rebooting the router helps, as there may have been an error in the entry of IP addresses.

Will progress be saved if the host exits the game?

No, in Local Wi-Fi mode the world exists only while the host is running. If the server creator leaves the game, the session will end for everyone, and progress made in that session by other players may be lost if they did not have time to exit and save the data to their devices (which in local mode usually does not happen automatically). It is recommended to make backups of the world manually.

Do both players need to buy the full version of the game?

Yes, for a comfortable game and access to all functions, both participants need the full version Craftsman: Building Craft. Free versions may have a limited number of slots for multiplayer or may contain advertising that interrupts the gameplay.

⚠️ Attention: The interface and names of menu items may vary slightly depending on the version of the game and the model of your smartphone. If you do not find the options described, look for similar buttons or refer to the official developer updates.
