@ManifoldMarkets more D&D = more better. Who runs the game, in this idea? Is it a manifold staff member?

@NcyRocks Chess is also the highest status game Manifold could add. Good for word of mouth or marketing stuff "they can even use markets to play Chess."

Minesweeper

A big multiple-choice market where every square is an option. Every once in a while, the square with the highest bet gets revealed. If it's safe, the people who bet for it get a small payout. If it's a mine, everyone else who participated gets the payout instead and the game ends.

Betting on a survey

The idea here is you release a survey to registered users, and then people bet on the outcome. Could be either resolve PROB based on proportions of votes, or resolve to the more popular choice. The survey could be categorical (which outcome will happen) or linear (what probability would you assign to X) This might make long term outcome betting more fun as you can bet on what people thing the probability is, and get a sooner resolution (although wrong-er... admittedly).

This was done once at least on Discord, watching Poirot I believe.

Chess
I learned some lessons from https://manifold.markets/Undox/communal-chess-game-will-white-win Lessons learned: 1. It is probably good to have some code tracking the official board position, since people may have differing ideas about what that is. 2. I made it initially one move total per person, but then the game grinds to a halt, I then made it unlimited moves per person, but 2 consecutive moves not allows. This was better but it allowed two people to collude to easily. So I would say you can only make a move if the last 2 moves are not yours.

Oh we will cap it to something like M$100 per user per market for this game, meant to include that in the original post

I don't know if I think this is a "good idea" but I admit that I would be snookered into participating anyway.

I like Chess since it's simple, widely known, and some Manifolk are quite good at it (I believe @mqp is rated 2100+) It could be pretty simple to do eg "If we play Qc3, will we win this game?" for a few candidate moves each round, using Futarchy to decide what to play next against an AI

Battleships
5x5 battleships?
answered
Mana & Dragons
I'd be reticent about playing any game with "last whale" markets, since I'd expect to lose mana to the last whale on average. Decision markets could work. "Conditional on casting lightning bolt, will the princess rescue the dragon?"

Trying to figure out the murderer is a common way to read detective novels and the like. Could work with a webcomic, fanfic, webseries, etc. Every day the author reveals a new story segment, adds a new market, and maybe resolves a market or two. Use a tag or author link to make it easy to see all markets for the story.
answered
Battleships
I could see this being a fun one-time thing but what we are really after is some sort of game that will draw users to our website daily for ~5mins (think wordle). Another concern I have over this proposition is having 81 markets created will be quite daunting for most users to interact with.
answered
Mana & Dragons
I'm not entirely convinced having some markets that are more adjacent to polls is necessarily something to avoid, especially if it is acknowledge it is a game. That being said we would have to be careful to avoid a situation where users bandwagon on the top response as all they care about is making a small % of M$ as opposed to caring about the game. We were thinking of creating a system where the top 3 responses are taken and one is chosen at random weighted to their probabilities. If we did want to make it very "prediction centric" we could make it so that the story is pre-written and users have to guess what event will happen or how the character will act, but I think this is less compelling than users actually impacting the story.

Just create a free response market and resolve to the correct answer after since reasonable delay. Earlier responders get a higher payout.

There is plenty of strategy here. As @JiSK mentioned, conditional probabilities evolve over time. Besides that, it is worth betting on coordinates that few other people bet on, since you will get more shares per Mana this way.

Even if placement is random, conditional probabilities will move nonrandomly when a guess is resolved. Eventually the community will converge on a correct strategy and the room for skill will disappear, but that could take a long while.

Maybe free-response markets could be used to predict the effects of certain actions (e.g. "Which action will yield the most gold?") instead of deciding actions?

Free-response market where each option is a 5-letter word. Bettors put M$ on the word that they think will be the best 1st guess for the following day's Wordle. I'm not sure what scoring system would be best. Something like: +2 for green (right letter, right place) +1 for yellow (right letter, wrong place) +0 for red (wrong letter) would probably work. Potential alternatives to that scoring system: * market where red is penalized * market where yellow and red are both penalized Another possible version of this game could look like people betting on the worst possible guess, with something like: +4 for green +2 for yellow 0 for red where the goal is to get the lowest score possible.
