Change the rule. Keep the game moving.
The fastest way to playtest your board game design online, rules included.
Describe your game's rules and Ludira turns them into a playable, rules-enforced prototype — no code, no manually re-explaining rules to every playtester. When something's not working, you fix the rule mid-playtest and the game keeps moving instead of resetting.

The engine enforces the rules, not the people at the table. Every demo game makes a link like this one; whoever opens it takes the other seat — no account, nothing to install.
The studio's public link is finalizing — the live demo below works right now, no signup needed.
Build it myself: start with an empty table and add your pieces and rules by hand. No email needed.
Ludira is solo-built and in free open beta. No mailing list, no tracking. No account is required to build — an account is optional: it keeps your games reachable from another computer, and it carries your free AI credits. Generating with the AI asks for an email, and it is only ever used to send you your own draft link.
What Ludira actually is
01
Describe the rules
Write your game's rules the way you'd explain them to a playtester — turns, actions, resources, win conditions. No code required.
02
Get a playable prototype
Your rules become a real, browser-playable game with the rules enforced for every player — nobody has to remember or self-police the rulebook.
03
Edit live, mid-game
Spot a broken rule mid-playtest? Change it on the spot. Every connected player's game updates instantly — no reset, no re-dealing, no losing the session.
See it played: a live demo
Before you design your own game, try one already built on Ludira's engine: five public-domain classics (tic-tac-toe, connect four, chomp, nim, three men's morris), each running on the exact same rules engine as the studio above — you against a bot, in the browser. No account, no email, no third-party trackers, live right now.
Where this actually stands right now
Ludira is a solo-built product in free open beta. Being upfront about what's real today:
- The core rules engine, live mid-game rule editing, and AI rules-to-game generation are built, live, and under continuous adversarial testing.
- The zero-signup demo above is live and free to play right now — no account, no signup, no waitlist.
- The design studio — where you actually build and edit your own game's rules — is rolling out; the devlog tracks exactly what's shipped and when. Paid plans are listed on Pricing, but self-serve checkout isn't connected yet.
- What we're not promising: we're not claiming Ludira will bring you players or an audience — this page is about the design/playtest tooling, nothing else, for now.
