It can be as easy or as complicated as you want. The good news is the bet with the best odds, the pass line bet, is also the easiest. That is all I did.

Here is the simple way to play. There are two modes the game is in. When there is no point, and when there is a point.
Mode 1 - No point
The table is fresh, no point. The thing that looks like a hockey puck (used to mark the point) will be flipped to the black side (it is black on one side, white on the other) and off to the edge of the table. You place a pass line bet in the pass line zone. It is marked as the pass line and goes all the way around the table where the players stand.
The shooter rolls. If he rolls a 2,3, or 12 that is 'craps' and you immediately lose your pass line bet. If he rolls 7 or 11 that is a win, and you get paid whatever your pass line bet was (if you bet $5, you get paid $5 and you have a total of $10). If the shooter rolls 4,5,6,8,9, or 10, that becomes the 'point' and you transition to Mode 2 of the game.
Mode 2 - point is established.
If the player rolled a 4,5,6,8,9, or 10 then the dealer takes the puck, flips it over to the white side, and places it on the number (marked on the table) that the shooter rolled. If the shooter rolled a 5, he places it on the five. Your pass line stays where it is (you can also now 'place odds' on your pass line bet). The shooter keeps rolling until he either rolls the point again (the 5 in this example) or rolls a 7. If he rolls a 5, you win, and get paid. If he rolls a 7, you lose, and the dealer takes your pass line bet. The pass line bet gets paid differently depending on what the point was. 4 and 10 get paid the most, 6 and 8 the least. If the shooter rolls anything else but the point, or a 7, then he keeps rolling.
Go to bodog, play it for awhile, and you will get it. The pass line bet is easy. You can keep it simple (like me) and ignore all that other **** on the table
