Sheep are especially sensitive to the exact moment of the turn of the tide. In this game, nine tethered sheep react, pull on the stakes, jolt the chairs and rattle the tea-cups. Bets are taken on the combined sensitivity of any three lines of sheep -- read vertically, horizontally, or diagonally. Since there are normally three tide-turns every twenty-four hours, it is normal practice to take the best of three results. Reliable clocks, calendars, and time-tables are used to determine the accuracy of the sheep's forecast.
