Play-test trading card games online

Untap.in is a free, browser-based table for play-testing trading card game decks. Build a deck, shuffle up, and test it against live opponents anywhere in the world - no download, no install, nothing to patch.

What you can do here

• Build decks - search the full card database for 50+ games, import a list from text or a URL, and share your deck with a link.
• Play live - open a table or join one from the public lobby, on desktop, tablet or phone - up to six seats at a table.
• Goldfish solo - test opening hands, mulligans and your lines against an empty seat before a real match.
• Draft, cube, and sealed - run booster drafts and cubes with friends. Bots fill the empty seats, and the deck you draft is played at the same table.
• Spectate and rewind - watch live matches, undo a misclick, or play a finished game back turn by turn.

Questions

What is Untap.in?

A free online table for play-testing trading card games: a deck builder over a full card database, a play area, and live opponents. It does not enforce the rules, so you play the way you would across a real table.

Is Untap.in free?

Yes. Untap.in is free to play-test - build decks, goldfish, draft, and join live multiplayer games at no cost. A table opens with four seats; the optional Power Up subscription opens the fifth and sixth and helps keep the servers running.

Do I need to download anything?

No. Untap.in runs in your web browser on desktop, tablet, and phone, and installs as an app straight from the browser. There is nothing to download or patch.

Can I import a decklist I already have?

Yes. Paste a plain-text decklist, or import one by URL from over 80 deck-building sites, then start play-testing straight away.

Can I play with friends?

Yes. Open a table and send your friends the link, or find each other in the public lobby. A game can be open to everyone or only to the people you invite.

Can I play my own custom card game?

Yes. Upload your own cards - art, text, and whatever fields your game needs - and build decks from them like any published game. Nothing enforces a game's rules, so a homebrew set plays the same as anything else on the table. To flesh one out fast, goldfish it against an empty seat, or sit on both sides in Deck vs Deck, a Power Up mode, and play two prototypes against each other.
