How To Play One Piece Card Game Online – App + OPTCGSim Install / Update Guide

How To Play One Piece Card Game Online

The best way to learn to play the One Piece Card Game right now is in person at a local event. The second best way is to play online. There is an official Tutorial App but there’s also a better way to play – OPTCGSim.

Right now, most people use an unofficial simulator to grind out games online and test decks. It’s a really good way of learning what different cards do and how decks will use them. It’s also great to see the current meta of what decks and strategies people are using before you play locally.

One Piece Card Game Tutorial App

Bandai have an official One Piece Card Game Tutorial App that is available on both Android and Apple devices. It’s pretty well laid out and has some simple tutorials, culminating in a couple of battles with starter decks.

As a tool for introducing beginners to the game, it does the job. It’s how I and many others first learned the basic rules. It’s also limited to just a few decks and cards, and the games are set up so it’s fairly easy to win.

Once you have those fundamentals down – there is a better way to place the One Piece Card Game online.

How To Play One Piece Card Game Online With OPTCGSim

OPTCGSim is a passion project made by a single developer. It’s unofficial, totally free to use, doesn’t use official assets, and is incredibly helpful for the community. It’s probably half the reason why the Global version is so widely played right now.

Note: The sim has versions for Windows, Mac, Linux, and Android. There is no working iPhone/iPad version right now. The version on Google Drive won’t quite work yet.

It’s pretty straightforward to use. You just build or import a deck, then find or host a lobby to play online. We’ve got a full visual guide below with some tricks and tips, plus how to get alternate arts in the game too!

How To Download + Install OPTCGSim

Steps 1 and 2 are optional but highly recommended. If you’re on the Discord you’ll know when there are updates or issues affecting all players. You’ll also be able to get help with issues and common problems.

Step 1 – Optional – Get Discord

Discord is a free chat program where you can join servers to chat about a certain topic. You can use it on the web, or download it for your PC or mobile device. Go to and click “Download for …” for your device, then install or just click “Open Discord in your browser”.

At – Choose the option that works for you

You’ll be prompted to create a username and password. Do that, then move to Step 2.

Step 2 – Optional – Join the One Piece Card Game server

Once you have Discord installed, click this link to be invited into a fan-run Discord server. It’s a really nice group full of helpful and passionate OPCG players. You should be prompted to open the server in your newly downloaded Discord app, or taken to the server on the web. If so, skip to Step 3.

If that doesn’t work, copy this text: Leave a comment on this article if any links are out and we’ll get back to you.

Then go to your Discord application on your PC or on your phone. On PC/Mac, look to the bottom left for a green “+” icon. You may need to scroll down to below your current servers.

On mobile you might need to press the gray three-lined “hamburger menu in the top left first to see a list of servers, then scroll down to the bottom left. Find the green “+” icon.

Press that, ignore the text about creating a server, and then press the “Join a Server” button.

Past the invite link above then press “Join Server”

Then paste in this link or even just type NJszccMeet and press “Join Server”. You’ll be taken to the One Piece Trading Card Game Community server. Welcome!

Step 3 – Download OPTCGSim

You can skip to point 5 in this step if you aren’t using Discord

Discord has lots of different servers for lots of different hobbies, events, and more. Each server has different categories and channels for different discussion topics. Some channels then have threads to organize discussions.

Think of it as a convention with different rooms for different speakers or purposes, and smaller booths for specialty topics.

To get OPTCGSim from Discord, we are going to find the right channel for OPTCGSim, look in the thread with the latest release, then find the latest link.

  1. On the left-hand side of the screen find the OPTCG-SIMULATOR category, then click the optcgsim-forum channel. On mobile, you might need to press the top left gray-lines hamburger menu to see the channel list.
  2. Click the pinned post at the top (with the blue pin icon). It should always have the latest release version.

  1. (Optional) We suggest you look at this in the full view by pressing the three dots (…) in the top right and pressing “Open in Full View”
  2. Either scroll to the top of the thread or just type !download in the latest Release thread to see the download links.
  3. You should see a link to this page, which you should click –
  4. The page has a list of different download links. You might want to bookmark this page and come back to it later when updating or making changes.
OPTCGSim Install Guide 5 Part 2
  1. The base version of the application doesn’t have any card images, as there are copyright of Bandai. However, there is a version with card images that an unknown person has made.
  2. Click the version you’d like. We think you should get the Swanky’s version with the images pre-installed.
  3. From the list of files here, choose the right one for the device you are using. For instance, on PC you are looking for the file with Windows in the name. For Android use the Android one.

Note: The sim is updated every so often. Check the forum and the pinned messages (the pin icon at the top of the #optcgsim-forum channel) for what version number you should get just in case the latest has major bugs. If in doubt – get the latest number version.

OPTCGSim Install Guide 6 1
  1. Hover over the file you want and press the download button, or click it and press Download.
  2. You then have to unzip the program on Windows/Mac/Linux or can install it straight away on Android. If you don’t know how to do that, here’s a handy guide to learning literally anything.
  3. Copy the whole folder to wherever you want it to be. Open that folder then click OPTCGSim.exe or whatever the filename is on Mac. Welcome to the sim!

Pro Tips for PC:
Move the folder to your desktop, or to somewhere like your documents where you’ll remember it. Rename the folder to OPTCGSim.
Right-click the OPTCGSim.exe file and select Send to > Desktop (create shortcut) to make a shortcut to the game on your desktop.
Later, when you come to update, you can just drag the new files into this folder and overwrite them. Then you won’t have to update your shortcut.

Step 4 – Choose Options

First, click Settings. Choose a name in the blank box, then you can choose some options while you’re playing. These will speed up gameplay and stop mistakes. We recommend ticking all of the boxes.

These will avoid common mistakes when playing

Step 5 – Build A Deck + Using The Deck Editor

Click “Deck Editor” on the main screen. You can select from a few pre-built options in the left drop-down, then click Load to take a look. Hovering over a card will show you the card details.

We suggest picking one of the pre-built decks, taking a look, then heading into a “Solo vs Self” game and learning how the sim and the card game itself work.

OPTCGSim Install Guide 8

There are lots of options to choose from here. Your deck is in the top box, and the cards you can add are in the lower box. The above-numbered things do the following: –

  1. Click the dropdown to view saved decks, and click Load to bring the deck into the editor.
  2. You can type the name of the deck and press Save to save it. A deck with the same name as another will overwrite the old one.
  3. If you have a decklist from a website like NakamaDecks or, you import it here
  4. To choose which card colors to see, click the tick boxes. You must have them selected to see any cards.
  5. Left-click on a card in the decklist on top to remove one. Right-click on the card to remove all copies of that card from the list.
  6. You can search by name, or even part of a name here. Bear in mind you’ll need to have the color selected. You can also search for a term or a name, like Whitebeard Pirates or Edward Newgate, or even things like Rush or OnKO, as well as OP02
  7. Your deck’s card total – including the leader – is shown here. You can go above 51, but you won’t be able to play the deck in most versions of the game.
  8. Click the cards in the lower part to add them to your deck.
  9. Press Clear Deck to clear your entire deck. If you have the deck saved already, you can load it again – unless you save it as a blank.
  10. Go back to the lobby to play.

Common Problems

  • Can’t see any cards? Make sure you have a color selected in the tick box.
  • If you click a card, it removes it from the deck. To add it back, click the tickbox of the color you want, find the card, then click it to add it back
  • There is a limit of 1 Leader and four of every other card per deck
  • The 51-card limit includes 50 cards in your main deck, and one Leader. You don’t need to add Don!! in the sim.
  • You can choose any color card in the sim, even if that Leader isn’t the same color. However, that won’t work in a real game. Your cards must match the color or colors of your Leader.
  • You can search by card name in the search bar on the right, remember to clear it after.
  • Check card sets by hovering over the card and looking in the bottom right-hand corner.

Step 6 – Importing / Exporting A Deck

If you find a deck on sites like or you can click an export or share button, then find the basic text list. If you copy that full list, you can then just press “Import Deck from Clipboard” in the “Deck Editor” and it will load the full deck.

You still need to name and save that deck but can use it straight away or make any changes you want.

In the same way, you can click the “Copy Deck List to Clipboard” and then import the deck to a decklist site to flaunt it. Many people just screenshot the deck in OPTCGSim and share that image.

Step 7 – Test The Sim!

Back on the main screen you can then click the “Solo v Self” option, select a couple of decks, and try the thing out by pressing “Start”. You should see the Leaders and both sets of cards in hand as you’re playing both sides.

The first thing you do is choose to keep the cards you’ve drawn or press “Mulligan” to shuffle them back and draw another five. From here, start clicking things and practicing!

Step 8 – Play Against Others

When you think you’re ready, click “Multiplayer”. You will get a few options:

OPTCGSim Install Guide 9 Select a meta
Choose the meta you want to play in. Practice the current set or for future releases
  • Western – All of the cards that are currently legal in play for the English release (or just a little ahead). Shows current bans and includes. If you play in a country where the cards are in English, probably play this.
  • Eastern – In Japan and the countries with Japanese cards, they are ahead and have more sets and cards to play with. Use this to get practice with upcoming sets.
  • Unlimited – Every card available now, plus any teased cards for unreleased sets that have been coded into this sim already.
  • Private – The same as unlimited but for private games. Create or join a game here and it won’t share your code to others.
OPTCGSim Install Guide 10 - Joining A Lobby
Choose your deck, pick a lobby, or host your own

On the top left you select the deck you want to use. You need to select this every time you come back to this screen.

In the middle, you’ll see the lobbies. You can click one to join a game but you should read what the text says first. This is important. People often put specific decks or sets that are trying to test.

The other important option is to host a public game. You can choose a name if you want to. You’ll be put into a lobby and someone should join shortly.

If you don’t see any games you can press “Refresh Lobbies”. If you want to play with a friend and don’t want to play with the public, go back and click the Private button instead.

You can press Quick Join to join the latest available lobby and jump into a game faster.

Step 9 – Have Fun!

Play a bunch of games, test out new strategies, find out what cards are best on different turns, and don’t be afraid to lose. Failing is learning if you take something from it.

The unwritten rules of OPTCGSim are:

  • Remember to press buttons to draw/confirm actions. Sometimes you’ll miss them.
  • Type gg at the end of a game even if you’re super salty.
  • Don’t take too long on a turn.
  • Don’t disconnect when you’re losing, play it out or click concede. It’s rude asf not to.
  • Always play another game!

The acronym in the name actually means One Piece Trading Card Game, not One Piece Card Game but we’ll ignore that for now…

How To Update OPTCGSim

Updating OPTCGSim is pretty easy, but isn’t automatic for all versions. To sum it up, just download the latest version and copy the files into the folder you already have OR install it into a new folder, and drag your decklists over from the Decks folder from the old one to the new.

Windows/PC Version

Currently, there is no in-game way of updating OPTCGSim on PC or Mac. You just need to download the new version, copy over the decks from the old one, and start the new version.

To simplify this, we are just going to drag or copy all of the new files from the new download and copy over the old ones. Full instructions below.

OPTCGSim Install Guide 11 Updating
Drag the new files into the place where the old files currently are. It will overwrite them.
  1. Open the location of the old folder where the main files are. Go into the folder where you can see the Decks, MonoBleedingEdge etc. folders, and the main exe files.
    • Optional – Copy the old Decks folder to somewhere safe, in case you lose them.
    • If you have custom cards or alts already installed, go to OPTCGSim\OPTCGSim_Data\StreamingAssets\Cards and copy the folders of the sets you have alts in to somewhere you can find them.
  2. Download the new version from
  3. Open the new zip file. In the zip, go into the folder where you can see the Decks, MonoBleedingEdge etc. folders, and the main exe files. Highlight these and drag them into the old folder.
  4. You can safely overwrite the files.
    • The only thing that might change is if you’ve made changes to the starter deck files without saving them as a different name.
  5. Open the new OPTCGSim.exe and check the decks are there
  6. Check all of the options you want are selected before going into a new game.
    • Pro Tip: Right-click the OPTCGSim.exe file and select Send to > Desktop (create shortcut) to make a shortcut to the game on your desktop.
  7. If you used Alt Arts and want to save time, drag the Cards folder from the old install to the new one and overwrite the new files. There is a guide to adding alt arts to OPTCGSim below.

Android Version

For Android, you just download the new .apk file and install it on your phone. It will overwrite the old game but keep all of your decks. It’s as easy as that. Your old preferences should be saved, but double-check before you jump into a live game.

Go to Batsu’s linktree here, and download Swanky’s version with the card images. Put the folder somewhere on your PC and run the OPTCGSim.exe file in the folder.

How To Use Alternate Arts In OPTCGSim

If you want to display the alternate art versions of cards, or even put in your own art for card, you can do so.

You can either repace every single art with the guide below, or just save the arts you want to use to your favorite folder, then when building the deck in the Deck Editor click Customize Images.

Windows/PC Version

You just have to replace the pictures in the OPTCGSim_Data > StreamingAssets > Cards folder on your PC. The image for each card is named by its ID and is a .png file.

You need to find the image to replace the original in a .png format, rename the file as just the ID, then put it in the correct folder. For instance

  1. Download card art for the alts you want to display: –
    • Update: A helpful person has collated all of the current alternate arts. You can download them from this Google drive link, then skip to Step 3. They are already named correctly but you need to put them in the right set folders as described in Step 4.
    • You can use the official source at or
    • An easier way to just find alt art is to go to and select the set or sets you want alt art for in the Set drop-down. Then click More Filters, and press the Alt Art slider.
    • Open the full-size image otherwise you’ll have a lower-quality version. Either drag the image from the browser to an open folder on your PC or right-click the image and save it.
    • You can also go to and click into the search, then click the Only Alternate Art option. Click the full image, then right-click and Save it.
    • The best images are from the official sites but they will have the SAMPLE text over the front. The unofficial sites are very accurate recreations made by fans.
  2. Once you have all of the images you want, make sure they are renamed to just the ID. For instance, if you download the alt art for OP01-002 Trafalgar Law and the file is named OP01-002-Alt.png you should rename it to just OP01-002.png
  3. Then you have to move the pictures from where you’ve saved them to the OPTCGSim_Data > StreamingAssets > Cards in the folder you use to store the sim.
  4. Make sure the card goes in the right set. So the OP01-002.png file needs to go into the OP01 folder.

You can keep the old images by moving them into a separate folder somewhere, or just overwrite the images, it’s up to you. You can also replace card backs for normal cards and Don!!, as well as Playmats, all in the folders in StreamingAssets.

Will There Be A One Piece Card Game Digital Version / App?

The current Tutorial app is definitely designed well enough that it could be a fully-featured digital version of the One Piece Card Game. However, right now Bandai hasn’t announced any plans to add more decks or let players face off against each other online.

That’s likely because right now they want people to play with (and buy) the real cards. The advantage of digital versions of card games is that it allows people to practice when locals aren’t available, try different cards and decks, and keep people engaged in the game.

The drawback is that if the game is good enough, many people will choose to play online instead of buying cards. That can be mitigated by having players purchase digital versions of cards and decks. However, Bandai seems to be focused on selling cards right now – which is fine by us because we have OPCTGSim, which at the moment does a great job as a One Piece Card Same simulator.

But wait! The Dragonball Super Card Game is one of Bandai’s other properties. It’s been waning in popularity recently but it was just recently announced there will be a Digital Version! There isn’t much info right now, but more will be released in March.

That means it’s totally possible we’ll get a One Piece Card Game Digital Version at some point. It could be that scannable codes in packs (like in Pokémon) are added so players are incentivized to buy the actual cards, but right now that’s pure speculation.

Hopefully, you enjoyed this article about one piece tcg online and the optcg sim. If you did, let us know what you’d like to see in a One Piece Card Game Digitial Version in the comments below.

  1. It’s fine they want you to buy cards to play but if thats the case BanDia should sell the cards online on their website or something because i never even saw any started decks in store until starter deck 8 and 9. And Im not paying over double the price to buy from some resaler.
