Think about it. When you toss a coin fairly you will get an even number of heads and tails in the long run. Every now and then you will get a run of four or five heads or tails, just by chance. After all, every time you toss there is a 50:50 chance of a head or tail coming down – and this doesn’t change depending on what the tosses before have been. If runs of 4 or 5 heads happen, it means that runs of 10 or even 20 can and will happen. Not very often at all, but they will happen. winning and losing streaks are what you can expect occasionally, just by chance. They do not need to be explained by ESP, magic or superior betting skill.

The shooter, or anyone wishing to bet that the shooter will win, places his bet "on the line" (in the area marked "Does Pass," "Line," or "Win" on various layouts) Anyone betting against the shooter places his bet in the area marked "Don't Pass." Anyone wishing to bet on a special contingency, such as that craps (2, 3, or 12) will or will not be thrown on the next roll, places his bet in the appropriate space on the layout; such bets are called proposition bets. The house maintains a mathematical advantage on all bets of about 1.4 percent, higher on certain layouts and special bets.

Soldiers in the Roman Legions used to shave down pig knuckles into the shapes of cubes, and toss them onto their inverted shields as a form of entertainment while in camp. Hence we get the term "to roll the bones". We do know that the game we know today as "craps" came to the United States from Europe.

Craps can be an intimidating game for the beginner. The table seems to have about a hundred different kinds of bets. Critical to the understanding of craps is that it is a game of rounds. The first roll in a round is called the come out roll. Sometimes the outcome of a round will be determined on the come out roll. In particular a 2, 3, 7, 11, or 12 on the come out roll immediately ends a round. If any other total is rolled (4, 5, 6, 8, 9, or 10) that number is called the point. The dealer will place a white puck on an area of the table to designate what the point is, in case you forget. If a point is rolled the dice will be rolled continuously until the same point is rolled again or a 7.
