The card room is open
Describe a card game. Deal it tonight.
DeckLex turns plain English into real, playable card games — the rules drafted with you in conversation, proven winnable by the engine, then dealt onto a shared felt. Or just sit down — the classics, Hearts to Gin Rummy, are already dealt.

The catalog
Play what people are making.
DeckLex is a marketplace. The classics were authored and verified by the house; the rest of the room is built by players like you. One bar for everyone: if it’s listed, the engine proved it plays.
Authoring
You talk. The house builds the game.
The rules of your childhood — the ones nobody ever wrote down — become a real game your friends can play tonight. No code, no rulebook formatting. A conversation.
Describe it
In your own words. “A shedding race where eights are wild and jacks skip.” DeckLex asks the questions a rules lawyer would.
Watch it compile
Your rules become a precise, machine-readable game — and if something can’t work, you hear it straight, with the reason, not after your friends are seated.
The engine proves it
Before anyone can play, the engine plays your game to completion. If it can’t be won, it can’t be published. Every published game carries that proof.
Deal it
Your table goes live in the room with your name on the rail — playable solo against the house bots, or with friends by invite.
DeckLex Verified
Honest to the ruleset. Every shortcut disclosed.
Card games live on trust — that the rules are the rules, and the deck isn’t stacked. We made both mechanical.
The seal means something
Verified = faithful to a stated ruleset. Where a game simplifies the classic, the table says so plainly — before you sit down, not in fine print.
Proven winnable
No game publishes until the engine has played it to a win — not spot-checked, played to completion, deterministically, with the proof kept.
No AI at the table
AI helps write the rules, then leaves the room. Every shuffle, deal and turn runs on a deterministic engine — and the server never shows anyone a card they shouldn’t see.
The honest bit Whist, as built: we count tricks, not honors — the classic scoring shortcut, declared right on the table.
Where to play
Your table, three doors.
