The Adventurer · Quest for The El Farol Bar Problem

The Thursday Decision

The Prompt

Recruit at least ten participants for a live El Farol game played over at least five rounds. Each round, every participant independently decides whether to "go to the bar." Announce only the attendance count after each round (not who went). The bar is "fun" if fewer than 60% of participants attend. Track attendance over rounds and observe whether the group self-coordinates, oscillates, or settles. Ask participants afterward what strategy they used.

Completion Criteria

The number of participants, the threshold used, attendance counts for each round, and a summary of the strategies participants reported using.
