Play The Long Watch

8 decisions across forty years. Choose what happens, when it arrives and whether it is done in the open.

Invented rule model, not a forecast. No real-world probability, organization or date is claimed. Your choices stay in this browser; the public ledger is closed.

The Long Watch runs in your browser, so it needs JavaScript to be enabled. Every rule it would run is published as plain text on the rules page, which needs nothing but a reader.

Rules version 1.0.0

Begin your watch

Three events are offered each era. The same choices always reach the same ending under the published rules.

Or replay someone else’s run

Ready to build lasting institutions? Play the strategy campaign: three regions, scarce resources, competing interests and twelve turns.

Using code? Get the same game rules and a runnable example.

Every rule is published — the measures, the events, what timing and manner do, the drift between eras and the conditions for each ending. Nothing is hidden, so nothing about your ending is a surprise once you have read them. A finished run becomes a link you can hand to somebody, and opening it replays the whole run against these rules rather than asking you to believe the ending.
