Best One Piece TCG simulators in 2026: how to play online

Bandai has no official game for playing the One Piece Card Game online against other people. If you want to test decks, practise or play with a friend who lives far away, you need a fan-made One Piece TCG simulator. In this guide we compare the eight most used options as of 5 November 2026: which platform each one runs on, what it costs, whether it enforces the rules for you and who it suits best.

A disclaimer before we start: ARENA is our own simulator, so you will see it on the list. We have tried to be fair to the rest. Where we could not verify a feature on a project's website or in public sources, we say so.

8 ways to play One Piece TCG online

ARENA (ONLYCHASES)

Our browser-based One Piece TCG simulator. We built it so you can play from any device without installing anything.

• Platform: browser, on mobile and desktop. Works on Windows, Mac, iPad, Android and iPhone with no downloads.
• Price: free. You sign in with a code sent to your email, no password.
• Rules: automated, with the official rules and every card.
• Ranked, tournaments and AI: ranked league with 8 ranks, from Stowaway to Pirate King, with an OP-17 Booster Box as the Season 1 prize; online Swiss tournaments with top cut; AI with 4 difficulty levels; private 1v1 rooms joined with a code.
• Decks: meta decklists load in one tap and you can build your own deck around any Leader.
• Language: ARENA's interface is in Spanish, English, French, Italian and German.
• Best for: players on mobile, Mac or iPad, and anyone who wants ranked, tournaments and AI in one place.

OPTCGSim

The longest-running simulator and the one the community mentions most. It is developed by Batsu and downloaded from its website.

• Platform: download. Its website offers versions for Windows, Mac, Linux, Android and iOS. When a new version comes out you have to download it again, and both players must be on the same version.
• Price: free.
• Rules: automates drawing, damage and Life, and according to its patch notes it implements card effects. Version 1.44a, released on 7 October 2026, added 87 already revealed cards from EB-05 and OP-18.
• Ranked, tournaments and AI: no ranked mode of its own; the community plays it through Discord ladders such as TCG Matchmaking. It has public and private rooms and Western (English cards), Eastern (Japanese cards) and Unlimited formats. For solo play it has Solo vs Self mode, where you control both sides. We could not confirm an AI opponent.
• Deck import: yes, by pasting a text decklist from the clipboard into the deck editor.
• Language: the most widely used version comes with English card images.
• Best for: players who want the most established community and don't mind installing and updating.

DuelVoyager

Untap.in

A virtual tabletop for lots of card games, with One Piece support. You'll find it at untap.in.

• Platform: browser on desktop, tablet and mobile. You can install it as an app from the browser.
• Price: free, with optional perks for supporters of the project.
• Rules: manual. You move the cards and the DON!! yourself, just like at a real table; the software does not check the rules.

• Deck import: yes, from text or from a deckbuilding site URL.
• Language: the website is in English.
• Best for: anyone who wants to play as if at the table, with no automation, and people who play several TCGs.

Tabletop Simulator

A Steam game for simulating any tabletop game. For One Piece you need a community mod. It is on its Steam page.

• Platform: download for Windows, Mac and Linux. There is no mobile version.
• Price: paid, around €19.50 (November 2026 price; it changes with sales). Both players need to buy it.
• Rules: manual. Some mods add buttons to draw, set up Life or refresh, but you enforce the rules yourself. Note: some One Piece mods have been removed from the Steam Workshop.
• Ranked, tournaments and AI: no. You create a game and invite whoever you like.
• Deck import: depends on the mod; some accept decklists in the same text format as OPTCGSim.
• Language: depends on the mod.
• Best for: people who already own it and want a free-form tabletop experience.

TCG Matchmaking

It is not a simulator. It is a Discord community that runs ladders and matchmaking, and the games are played on OPTCGSim or another simulator.

• Platform: Discord plus whichever simulator you use.
• Price: we could not confirm this.
• Rules: those of the simulator you play on.
• Ranked, tournaments and AI: ranked with ratings and a ladder; moderators act as judges. No AI.
• Deck import: depends on the simulator.
• Language: not confirmed.
• Best for: competitive OPTCGSim players who want strong opponents.

Bandai's official app (ONE PIECE CARDGAME Teaching)

Bandai's only official app for playing the game. It is a tutorial, available on the App Store and Google Play.

• Platform: app for iPhone, iPad and Android.
• Price: free.
• Rules: enforced by the app, with a tutorial mode that walks you through the basics.
• Ranked, tournaments and AI: it has a free battle mode against the computer. The store listing does not mention games against other people, ranked or tournaments.
• Deck import: no. According to reviews, it only includes preconstructed decks from the first starter decks.
• Language: English.
• Best for: complete beginners. Its last update was in March 2025, so it is no use for practising the current meta.

Data as of 5 November 2026.

Which one should you choose?

If you are just starting out

Start with Bandai's Teaching app to learn the turn structure and phases, or read how to play the One Piece Card Game. After that you need a simulator that enforces the rules for you, so mistakes don't slip through. On ARENA you can play against the AI on the easiest level and move up when you feel comfortable.

If you play competitively

OPTCGSim with TCG Matchmaking is still the combination with the longest history in the international competitive scene. DuelVoyager has ranked and replays in the browser. ARENA has ranked with 8 ranks and an OP-17 Booster Box as the Season 1 prize. The best approach is to try more than one and stick with whichever has opponents at your level at the times you play.

If you play on Mac, iPad or mobile

Not having to install anything matters a lot here. ARENA, DuelVoyager, OneSimulator and Untap.in all run in the browser. OPTCGSim has Mac, Android and iOS versions, but you have to download them and update them with every release. If you want to play One Piece TCG online on a Mac or your phone with automated rules, ARENA runs in the browser with no downloads.

If you want to play with a friend

Almost all of them work. On ARENA you create a private room and send your friend the code. OPTCGSim and OneSimulator also have private rooms. If you'd rather move the cards by hand, like at the table, Untap.in is free and needs no install.

If you want to practise before a tournament

What helps most is playing lots of games in a row against meta decks. First check what is being played in the best meta decks and in our OP-18 and EB-05 meta forecast. Then play a few Swiss rounds to see how your deck holds up. If you are on Rocks, the full decklist is explained in our Rocks OP17-039 deck guide. And before you sign up, check the banned cards: whichever simulator you use needs an up-to-date banlist.

They are all unofficial projects

None of the simulators on this list is an official Bandai product, ARENA included. They are all fan projects (in Tabletop Simulator's case, the One Piece mods) that use cards whose rights belong to Bandai. The only official app for playing is Teaching, which is a tutorial. As far as we have been able to check, as of November 2026 Bandai has not announced an official online game.

This has consequences. In August 2026, according to community reports, two simulators, Project Raftel and OPTCG Rush, received notices to shut down. Any simulator, ours included, could have to close if Bandai asks. That is why we recommend not relying on just one and keeping your decklists saved as text, so you can take them elsewhere.

Simulators are for practising and testing ideas. Official tournaments are played with physical cards, and in Europe in English. If a deck convinces you in the simulator, the next step is to build it for real; we explain how in how to build a One Piece TCG deck.
