some cases posing as Chinese to infiltrate the games. In San Jose, California, a typo in a local printed law led to charges being dismissed against several bettors. Despite its illegality, it was estimated that 100 fan-tan parlors were operating in San Francisco's Chinatown around the turn of the 20th century. Because of the police raids, fan-tan parlors adopted double-entrance security measures: after entering through the street doors, a bettor would have to pass through a hallway and a second interior set of doors. If the guard posted on the exterior doors did not recognize the prospective bettor or the guard raised an alarm in the event of a raid, the interior doors, often heavily reinforced with iron, would be shut and barred, giving the fan-tan patrons and parlor time to dismantle the game, conceal evidence, and flee the premises. Fan-tan is no longer as popular as it once was, having been replaced by modern casino games like Baccarat, and other traditional Chinese games such as Mah Jong and Pai Gow. Fan-tan is still played at some Macau casinos. The game The game is operated by two people: the "tán kún" or croupier, who stands by the table at position no. 1, and the "ho kún" (clerk or cashier), who stands to the left of the "tán kún". A square is marked in the center of an ordinary table, or a square piece of metal is laid on it, the sides being marked 1, 2, 3 and 4 in anti-clockwise order; alternatively, the sides may be marked 0 through 3, with 0 taking the place of 4. The banker puts on the table a double handful of small objects (buttons, beads, coins, dried beans, or similar articles), which he covers with a metal bowl. When all bets are placed, the bowl is removed and the "tán kún" uses a small bamboo stick to remove the objects from the heap, four at a time, until the final batch is reached. If the final batch contains four objects, those who wagered on position 4 (and specific bets that include position 4) win; if three, the backers of No. 3 win; if two, the backers of No. 2 win and if one the backers of No. 1 win. A variant substitutes dice instead of counting the objects by fours; the remainder after dividing the sum of the dice by four is used to
