The hosted playmat's limits

The hosted playmat at tcgreplay.demo.gs is free and small. It runs on a single server, so it keeps games only in memory and serves a limited number of players at once. Here is what that means for you.

What it keeps

Each Google account has one game at a time, held in the playmat's memory: the imported battle log, the moves on the board, its branches and the assistant's coaching notes. Importing or starting another game replaces it. See privacy for everything it keeps about you.

When games are dropped

• After 60 minutes without activity. The next time your assistant uses the game, it is told the game expired.
• Whenever the playmat is updated or restarted, which can happen at any time: every change to tcgreplay is deployed straight away, and every game is lost when it is.
• When your last sign-in ends.

Keep the record

To come back to a game later, ask your assistant for its record and keep it somewhere safe, such as a note. The record holds the battle log, both decklists and everything needed to rebuild the game exactly.

Give me this game's record so I can keep it.

Later, paste the record into a chat and ask your assistant to import it: the same game comes back, move for move. Branches you made and coaching notes aren't part of the record.

How many players and requests

• It serves up to 10 signed-in players at once. A place is freed when a player's game is dropped or their last sign-in ends.
• Each account may make up to 300 requests a minute, from the assistant and the board together. Normal play stays well under it.

Messages you may see

"tcgreplay is busy"

The playmat already has 10 players signed in. Your assistant may say "the server is busy: it already has the most signed-in users it serves at once (10); try again later". Try again later, or run it on your desktop (below).

"too many requests"

Your account went over 300 requests a minute: "too many requests: this account is limited to 300 requests a minute; try again in …s". Wait the few seconds it says and carry on.

"Your game expired"

The game was dropped after 60 minutes without activity. Import its record again to carry on.

When it's full: run it on your desktop

The playmat is open source and runs on your own computer with the Claude desktop app, with no sign-in and no limits, and your games stay on your machine. See running it on your desktop.
