Complete each task in any game you own, on any platform. Once you've used a game for a task, you can't reuse it for a later one — that's tracked per player, not for the whole group. Honor system, not enforced in software.
Where it makes sense, start from a fresh save rather than one already in progress. Doesn't really apply to roguelikes/procedural games.
There's no judge. Marking a task done opens a 60-second objection window. Others can vote "disagree" if they don't buy it — silence counts as agreement, and you can't vote on your own claim. If a majority of the other active players disagree, it's rejected (no penalty beyond lost time). A tie does not reject.
With N active players, 1st confirmed completion scores N points, 2nd scores N-1, and so on down to 1. Placement locks in when a claim is confirmed (window closes clean), not when it's claimed — a fast disputed claim can be overtaken by a slower undisputed one.
Suggested time limits are just a reference countdown — nothing auto-advances the group. Anyone can propose moving on; everyone active has to agree, whether or not the task was completed.
If someone goes offline mid-session, the rest can vote to kick them — majority of active players, same tie-doesn't-pass rule as claims. A kicked player stops counting toward votes and scoring going forward, but keeps whatever points they already earned.
Once a lobby starts, no new contestants — but spectators can join any time to watch the live scoreboard. Minimum 2 players to start.
