Three steps to a free tower of Brewerkz golden ale: First, “like” their page on Facebook. Second, be the first to answer an F1 trivia question they’ll post on the Monday of each F1 race week. Finally, stop in at either one of their outlets (#01-05/06 Riverside Point, 30 Merchant Rd., 6438-7438; #01-06/07/K1 Singapore Indoor Stadium, 2 Stadium Walk, 6345- 9905) to watch the race and claim your tower. Simple enough?
