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 2023-9-22, 365 players remain.

The market resolves to the calendar year in which Lorxus first forgets to check in to Tontine, dying and losing the game in the process, or to the calendar year in which Lorxus wins Tontine, if they should win. If Lorxus participates in a split, the market will resolve to the calendar year during which the split was enacted, not the year when it was agreed to, if the two should differ.

I will add new choices as they become necessary.
