Not long ago, this activity was limited to a select audience. Mainly, people who had immersed themselves in the nuances of the games and knew the underlying statistics. Today's casinos couldn't survive on this market. Not only are the profit margins on such patrons minimal, but the customer base is far too small to support the myriad of betting businesses now booming at seashores, in deserts, along riverbanks, aboard ships, and on Indian reservations near you. One reason casinos are so appealing is that the games may be intricate internally, but are easy to play.
Any solid citizen can place a bet, and can win when doing so.
The mechanics of the popular games can be mastered by briefly watching the table or machine, and maybe getting a little instruction or coaching from another player, a dealer, or an attendant. Some players, however, oversimplify. Other players overcomplicate. Baroque schemes involving wagers of different sizes on elaborate combinations of results at craps and roulette. Rigorous betting progressions based on previous runs of wins and losses at blackjack.
