Untap.in is a free, browser-based table for play-testing CCG and TCG 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 full card databases for 40+ games, import a list from plain text or by URL, and share it with a link.
• Play live - open a table or join a game from the public lobby, on desktop, tablet, or phone.
• Goldfish solo - test opening hands, mulligans, and your lines against an empty seat before a real match.
• Draft, cube, and sealed - run booster drafts with friends; bots fill any empty seats so a pod is always ready.
• 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. It gives you a deck builder over a full card database, a virtual 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. Optional supporter perks help 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 popular deck-building sites, then start play-testing straight away.

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 exactly like a published game. Untap.in does not enforce any game's rules, so a homebrew set behaves the same as anything else on the table. Solo play is the fastest way to flesh one out: goldfish a deck against an empty seat, or sit on both sides in Deck vs Deck, a supporter mode, and play two prototypes against each other.
