AI-coded online Monopoly clone: the AI refuses to copy it

Black Gold: the Monopoly the AI forced him to invent

Can you build an online Monopoly without writing a single line of code and without the AI telling you to take a hike over copyright? According to the inventor, yes, and the result is already up and running with games between real people. The author puts it plainly: Claude has been refusing for days to recreate games with rights attached, so the board had to be renamed Black Gold, a self-confessed copy of the Parker Brothers classic. The idea doesn't come out of nowhere: in Valencia, Falomir Juegos used to sell Superpoly, a shameless copy with Valencian street names, and that's where the local nod comes from.

The invention works. Some players have chained together several games and even describe themselves as hooked. The mechanics are the usual ones: board, properties, rents and an AI acting as banker and rival. What changes is the wrapper: the game was built with the help of language models, a method some call vibe coding, which lets you ship a working product without knowing how to program. The question hanging in the air is how far that counts as programming or just asking nicely.

Online games between real people

A multiplayer mode does exist, though with fine print. To play against another human you have to create a room and wait for someone to join, or enter one that's already open. The process is so makeshift that the first question that comes up is logistical: how do you create a room. The answer is in the menu: Online Game, Join, Create Room. Three clicks and then wait for company.

That's where the classic bottleneck appears. Playing online requires real friends willing to connect at the same time, and that's harder than finding a vacant lot on the board. The invention solves the technical problem and leaves the social one untouched.

The AI as a rival: generous with itself, stingy with you

The artificial opponent's behaviour is something else. According to one user's experience, the AI almost never accepts a property trade when a person proposes it, but among its own tokens it swaps them with suspicious enthusiasm. It's not a code bug: it's a design bias that turns every negotiation into an uneven contest.

The detail is funny because it strikes at the heart of the game. Monopoly isn't won by rolling dice; it's won by negotiating. If the machine stonewalls the human player while opening up to its own kind, the game stops being a board game and becomes an exercise in patience.

From Valencian Superpoly to digital Black Gold

The clone has history. Falomir Juegos' Superpoly copied Monopoly with Valencia street names, and that tradition of shameless, legally dubious copying is what inspires the current renaming. The difference is that the copyist is now a language model with sudden scruples.

The quality leap over cardboard is obvious: saved games, AI, online rooms. The ambition leap too. Some are already asking to expand the catalogue with other classics of the era, like Bancarrota, to complete the trilogy of cheesy eighties board games.

In the end, the paradox is neat: a tool that refuses to reproduce a copyrighted game ends up giving birth to a clone with a new name, invented streets and an artificial banker who cheats. The video game industry has been doing exactly that for decades, with bigger budgets and less charm.
