https://tontine.cash/ is a MSCHF game. On 2021-12-27, 7141 players each paid $10 into a central pot and have been required to check in at least once a day by midnight EST/EDT or else be eliminated. The last remaining player will win the pot. As of 2023-12-13, 318 players remain.

Each choice in this market resolves YES if the living count is 300 or less as of 12:05 AM EST on its labelled date, and NO if the living count is 301 or more at that time. It resolves early to YES if the living population should fall to or below 300 before that time, and to N/A if the game is canceled for any reason. I reserve the right to extend the closing time and add new choices if I judge it necessary.

CAUTION: I made typoes in some of the choices. All dates should be in 2024. This is no longer true now that it's possible to edit choices.
