Cloning MB's Hotel with AI: an afternoon of code and legal doubts

He recreated MB's Hotel with AI in an afternoon and already antiestéticars Hasbro

Recreating a classic board game no longer takes a week of programming or a team. It takes an afternoon. That's the claim of the person who built a playable version of MB's Hotel —the one with the buildings and the rent— using Claude Code, an AI coding assistant, and got it running on his own website. According to its author, the result still needs plenty of polish: "There's still a lot to debug and improve." But it already has a domain, it already has game rooms, and it has already raised the first uncomfortable question: can Hasbro, the trademark owner, sue him?

The short answer, according to a participant who warns it isn't legal advice, is that game mechanics are not protected by copyright. The long answer is that almost everything else is: the commercial name, the board art, the literal texts of the rules and the names of the original hotels. And the trademark owner has a track record of sending cease-and-desist letters when a clone becomes visible. The author sums it up wryly: "I know a random domain costs 12 bucks a year, but I don't know whether to pay it so you guys can enjoy it."

From an afternoon of code to the real barrier: selling it

The conversation quickly turned to what really separates an afternoon project from a business. The sharpest diagnosis: execution is no longer the barrier to entry, because what used to cost tens of thousands of euros now gets done with a couple of well-crafted prompts. The barrier is commercialization. "You could do it in an afternoon, I could do it in an afternoon... now go sell it," one participant sums up. And the creator himself accepts it: "I doubt anyone would pay for this as SaaS."

The skepticism about the product is real. Some flatly declare that this "pile of junk" couldn't be monetized "in 10 lifetimes," and the author replies that he isn't looking to monetize but to play. The discussion splits between those who see a phenomenal prototyping tool and those who think AI produces game designs of debatable quality. Nobody has presented a revenue figure yet. Nor a cost figure.

The technical problem nobody saw coming: the URL

Building the game was the easy part. Serving it to the world, not so much. The creator ran into Cloudflare changing the URL every time he restarted the tunnel, and faced the dilemma of opening router ports, exposing his home IP or paying for hosting. A rundown of the downsides: manual HTTPS certificate, Let's Encrypt renewal, confirming the name every 30 days on the free plan, and the risk that the operator uses CG-NAT, which breaks the whole setup. The solution suggested from the floor: ngrok, which offers a free static domain per account.

In the end, the author bought the domain and announced a partnership with another hobbyist who runs a similar site, with mutual banners. From nothing to a commercial venture in seven days.

The charm of the original the clone can't replicate

The sharpest analysis isn't legal or technical, but about design. MB's Hotel worked because of the human factor: catching your opponents cheating, bad decisions and saves by sheer luck. "Of course the fun is catching people cheating, making wrong decisions and being saved by luck," notes a veteran player. A digital clone, by definition, removes that shared table. And on balance, another recalls that in the original, whoever bought the most expensive hotel won 95% of the games, which raises the question of whether nostalgia can survive a version without flesh or elbows.

From hotel to strip club: the reinvention route

The way around the copyright problem with the most potential is also the cheekiest: change the theme. The proposal is to replace hotels with nightlife venues, starting with the cheapest roadside ones and ending with the most luxurious, with new rules to make it unpredictable. The idea, they say, besides dodging the trademark, could make it go viral. The author leaves it up in the air: "I'll think about it."

Meanwhile, AI is already being used to set up mystery role-playing games with 11-year-old kids, complete with maps, character sheets and a script. Same weekend. The conclusion writes itself: if anyone can clone a classic in an afternoon, the value is no longer in the code. It's in the domain, the community and the brand. And in knowing when to change its name.
