I made a betting game called Hindsight (AI slop rulebook at https://hindsight.markets/rules). At last year’s Metagame conference I playtested a face-to-face version but ultimately we gave up trying to come up with methods to trade the chips around conveniently.
The online version is a “TV party game” like JackBox where players view public info on a common screen and private info and decisions on their phones.
Each player starts with 100 chips. The game progresses in a series of rounds until all players but one are bankrupted. In each round there’s a hidden target year between 1900 and 1999. The round has three stages and during each stage:
A clue is revealed about the year—a birth, death, or event (“Grand Rapids, Michigan becomes the first city in the world to add fluoride to its public drinking water”).
There’s an auction in which the players bid down how wide a market they’re willing to make (“I’ll quote a market six years wide”… “I’ll do four”…).
Then the market maker presents a bid and ask price and everyone else must buy or sell N contracts with the market maker where N is the round number. (The escalating stakes prevent the game from going on forever.)
After all three stages, the year is revealed and the contracts settle at one chip per year of distance. The slop rulebook includes other details like who eats the losses when someone goes bankrupt.

I'm trying to test out the game some more: https://signal.group/#CjQKIKhbem4Stz_jiIo8-ZPADFh03t8836fSNFEcMxu_iVYNEhD_NvYQw2RkzfPonZaPvhYZ
