Why People Get This Wrong
People often assume that the number of chairs is randomly chosen without regard for player count, leading them to argue about why there aren't enough chairs for everyone. The confusion arises because they overlook the explicit instruction to arrange exactly one fewer seat than the number of active players, which directly contradicts their assumption and leads to disputes over seating arrangements.
Official Verdict
Count the participating players.; Arrange exactly one fewer seat than the number of active players.; Explain the route, direction, permitted movement, stop signal, tie procedure, and safety expectations.
