Three ways to set sail
Pick your rival
The same three ways the «Play» hub opens: online, against the AI or with friends.
- Online ranked
Against the world
Matched by rating, with Glicko-2 seasons, a clock with a time bank and a replay of every match.
Find a match - Against the AI
A rival that learns
Easy, Normal and Hard. Hard is a trained neural network that never sees your hand. Three matches need no account.
Play against the AI - Rooms with friends
Your code, your table
Make a room, share its six-letter code and play. With spectators live or delayed.

Questions
Is it free?
Yes. Grand Table is free, with no ads and nothing to buy, and it runs in your browser: there is nothing to download.
Do I need an account?
Not to look up cards, follow the lessons or play three matches against the AI. With a free account (Google or Discord) you play online and without limits, and keep your decks and replays.
Is it official?
No. It is a fan project with no ties to Bandai or the One Piece Card Game; the card images belong to their owners.
Does it work on a phone?
Yes: the table fits an upright phone, plays with touch and can be installed as an app from the browser.
Which rules does it use?
The full rules: the engine resolves every automated effect, attacks, blocks, Counters and Triggers, so you only make the choices a player makes.
How good is the AI?
There are three levels. Hard is a neural network that learned from more than three million matches and never sees your hand or your deck.
