In On The Rocks, players select 3-4 drink orders for each of the three rounds. Players then roll the dice and draft that number of marbles from the shaker bag. They then place the marbles in the centralized mixing area jiggers one at a time clockwise, then select one bowl. They then place all ingredients on their player board based off the recipe cards. The first player to complete all three orders will call `Last Call`, triggering the endgame, with all players having one remaining chance to complete their final orders. Players add up their final score based off the drinks completed and tips earned, with an additional tip for completing all orders.
