One: it would offer no human assumptions.

Two: more importantly it should and could include the trading part. (the op's video had some, but it felt really really limited from what I gathered)

It is really rare to see trading to be implemented. Yeah, it is the hard part but in competetive monopoly, it is big part.

I am yet to figure both input/output spaces for it. As soon as I figure them, I probably will do proper zero-style ai for many games.

Also my english pronunciation sounding like bucket full of rusty nails being dragged on motorway, makes the freeform so frusturating. Naming things is such paain at that point.

But oh, how much do I wish I could get it working.

Games between my brothers and me, rules such as: Specific card plays from next player. Or You are allowed to play +- 1 instead of exact same.

Nasty ones like: Third red is illegal. You are not allowed to put card, that would make sum of last three to be more than 15.

Those are quite fun. But probably my all time favorite is: "Eights live backwards"

I could live it at that, but the deeper explanation is that it is illegal to keep eights in had same way to other cards and it must be played up-side down.

This rule is the one my brother broke when he was shuffling the deck and got thought about "fixing" the eights.

Since some rules can be really rare and some really common, we started to do in expert games that the rule maker can set the card penalty. Multiple times per play? Basic 2 card punishment. ~once per game? 3-4

Rarer than that? +5, go wild as is the name of the game.

With newbies, standard 2 card punishment keeps things simple.

When each person have 2-4 rules from them and to keep all the other hidden rules in mind, the fun is chaos and chaos is fun.

It is also cool to debrief after and discuss with people if anyone managed to guess the others rules.

Cards had no meaning, there was no turn nothing.

But that is bit too lose base.

From our exploration we saw that rules that say you must do something are waaay more fun ad clearer, than rules like you can or can choose not to do. The choise rules made it basically impossible to detuct and even with in the context felt like the other is possibly cheating.

We also saw that people were quite concervative and really really hesitant to alter the base game rules.

Thou if we played couple of games and then chatted about everyones rules, and then reseted the game, people would open up bit. But the base rules (of basically uno) were quite sacred to break for people.

Your link seems bit like mix of Mao and it.

And it does seem to have "the commercial" version of Mao.

I should look into it more.

I can see that thou. I often had to give example rules for people, thou I feel like it robs part of the fun.

With more experts it could make things better, if they go easy on start. If they go full on with super hard rules, the half attention newbies would be lost.

Thou if the newbie really wants then they could learn in that big expert play too.

After that many people find it really hard to grasp the rules and possibilities. "How can the rules change without anybody knowing?" "How can they be enforced?" And so on.

To me the ideal would be no rules explained but as the embasidor, I do not get such possibility.

To others I explain some rules and example rules, such that we often want to sosialice so while you can make speaking rules they may be bit meh.

No one but one person made voice rules. My god I got burned in that game. I was constanly speaking as the explainer and keeping turn order up. I did not figure it why I got so many penalties from them, I had small feeling but could not figure the exact thing.

Turns out he was bit annoyed by me and the rule was: "you are not allowed to speak on your turn"

Obv I was not mad, I was amused when I got interesting game. Good times.

I wanted to try, luckily using siblings is not considered war crime. Since I had read about it in wikipedia we did not have culture to base it on. It morphed to basically uno with normal playing card deck but winner gets to make new rule, any rule. They will enforce it but they will not tell it to anyone else, they will just comment: "you broke rules, take penalty"

Since we played it way too much with siblings, we had times where my brother took 15 card penalty on game start. There was ~4 day trip we played near 30h of Mao.

I still love it, but can't play it any more since people rarely have attention to detuct the hidden rules. But also I feel creatively blocked since I can't make super complex rules when playing with new people, and the magic between my siblings has dimished bit.

Thou the new scanners didn't like my 3 stacked card decks or the 2 of 250ml "milkshakes".

Funny that the milkshakes needed to be drug tested while my 500mil smoothie was totally fine.
