YGO Omega Install Guide

This YGO Omega install guide covers every platform. To install YGO Omega, open the download page, get the file for your system, run it and let the first update finish. Then press Online and authorize the game in Discord. The game is free and every card is unlocked from the first launch.

Windows, Mac and Android take a few minutes. iOS needs a computer, because the game isn't on the App Store and has to be sideloaded. If you're already installed and just want to play, the Beginner's Guide picks up from your first deck.

Every build is on the download page. It always points at the latest release, which is also published on GitHub.

Every platform needs at least 4 GB of free space, and 6 GB is recommended. On desktop, the minimum graphics are Intel HD Graphics 3000 and the minimum resolution is 1280 x 720. The download page lists the recommended specs.

1. Install the Discord desktop app and leave it running. The game needs it to go online.
2. Download Omega_Installer-Windows.exe from the download page.
3. Run the installer and follow the prompts.
4. Open YGO Omega and let it update.

The installer is optional, because the Omega Launcher alone can install the whole game. It's still the better choice for most players: it adds the Windows Firewall exceptions, checks for updates and lets you uninstall from the Control Panel.

1. Download Omega_Launcher-Mac.dmg from the download page and move the app to Applications.
2. On an Apple silicon Mac (M1, M2 or later), right-click the app and choose Get Info.
3. Check Open using Rosetta. Intel Macs can skip this step.
4. Open the app and let it update.

If the game won't start, reset it from Terminal. This assumes it's in Applications:

cd /Applications/YGO\ Omega/YGO\ Omega.app/Contents/MacOS
./YGO\ Omega --reset

Open the game, close it, then open the updater again.

1. Download linux-x64.zip from the download page.
2. Extract it to a folder your user can write to, since the game updates itself there.
3. Run the game from that folder and let it update.

Discord has to be running for online play, the same as on Windows. For distro-specific problems, ask in the Omega-help channel.

1. Download android.apk from the download page on your phone or tablet.
2. Open the file. If Android blocks it, allow installs from that app when prompted.
3. Open YGO Omega and let it update.

If you drop offline during duels, turn off Battery Optimization for the game, or the setting that closes apps in the background. The name changes between phone makers, so search for your model if you can't find it.

YGO Omega isn't on the App Store, so you sideload ios.ipa with a Mac or PC. Try AltStore first, and use Sideloadly if it fails.

1. Download AltStore, install AltServer on your computer, then use AltServer to install AltStore on your phone.
2. On your phone, download ios.ipa.
3. Open AltStore, go to My Apps, press + and select ios.ipa.

If a step fails, the AltStore FAQ covers the common errors.

1. Install Sideloadly on your computer.
2. Download ios.ipa to the computer, not the phone.
3. Connect the phone, open Sideloadly and press Trust on the phone when asked.
4. Select the phone, add your Apple account and drag ios.ipa into Sideloadly.
5. Press and sign in to your Apple account when prompted.

1. Launch the game and let the first update finish. It's about 2.9 GB, so use a stable connection.
2. From the main menu, click Online.
3. Discord asks you to authorize YGO Omega. Accept it. You can't play online without this step.

If you land on a blank background or get disconnected, work through the next section.

Try these in order:

1. Check the Discord authorization. If you missed or denied the prompt, close YGO Omega and Discord, open Discord first, then open the game and accept.
2. Check your firewall. The installer only adds exceptions to Windows Firewall. Any other antivirus or firewall needs a manual exception for YGO Omega.
3. On Android, check battery settings. Turn off Battery Optimization for the game, as in the Android section.
4. Ask in Omega-help. The channel is on the Duelists Unite Discord.

If a card behaves wrong, that's a bug rather than an install problem. Confirm it with a judge in the Discord Rulings channel, then follow the steps in Bug Reports.

The defaults work on most machines. If the game runs slowly, change these under Settings > Graphics, starting at the top:

Two more that matter to new players:

• Language changes the interface and Card Language changes card text. They're separate settings, under Other.
• Update Server and Game Server should stay on their defaults unless the Omega team tells you otherwise.

Your images go in the game folder. On Windows it's here:

%userprofile%\AppData\LocalLow\Duelists Unite\YGO Omega

You can also open it from the game: go to Settings and click the icon at the top right.

JPG loads faster and PNG looks better.

Name a sleeve image exactly like the deck it belongs to: the deck Aroma uses the image Aroma. A deck with no match gets a random sleeve. Sleeves only appear while you're connected online, and the turn card button in the deck editor previews them.

Opponents see your sleeves and mat if you're a VIP, so keep them PG-13. The download page explains VIP.

YGO Omega doesn't sync local files on its own. The free personal version of Resilio Sync keeps your decks, sleeves, replays and deck thumbnails the same on every computer. Install it normally, but not as a service.

On your main computer:

1. Open Resilio Sync, click + at the top left and choose Standard Folder.
2. Type %userprofile%\AppData\LocalLow in the address bar and press Enter.
3. Open Duelists Unite, select YGO Omega and click Select Folder.
4. Share the folder by emailing yourself the link.

• Follow the Beginner's Guide from your first deck to your first tournament.
• Build a deck in the Deck Builder and load it into the game.
• Read the Format Primer to pick what to play.
