Craps is, in its essence, a game about guessing what the next roll of the dice will be. Knowing what number each of the bets wins and loses on is critical if one is to have any success at the craps table. And not just that, but how long the bet will remain on the table and what it's payout is. To further add to the complexity, the game is played a myriad of ways around the world, with Las Vegas rules being different than Monaco or Atlantic City. Within this cornacopia of bet options comes an equal amount of strategies.

Craps is played in rounds, revolving around the 'point' being 'on' or 'off'. At the beginning of a round, the point is 'off'. The rolling player rolls the dice until they roll a 4, 5, 6, 8, 9 or 10. This results in the 'point' being set and turned 'on'.

Below you can see the point is set to 6.

Now the rolling player will role until the 'point' is rolled again, or a 7 is rolled.
Either will end the round and turn the point 'off'.
A new round begins and the next player gets to roll.

To place a bet, click on the bet you want to place to bring up the Bet Menu.

The numbers in parenthesis are the payout. In the case above, the 'Pass Line' bet pays one to one.
Use the + and - buttons to adjust your bet amount.
Your current bet amount is denoted by 'Your Bet'. The new bet amount is denoted below in green as 'New Bet'.
Press the 'Place Bet' button to save your new bet. Once your new bet is set, the bet on the table will turn green and display your current bet amount.

To roll the dice, you can either click on them, or press the Space bar. You will know you rolled the dice because they will illuminate and play a sound. Fun!

When you're new to the game, it is typically recommended to play the Pass Line until you get a feel for the rhythm of the game. Next, you might venture into playing the Come, which will expose you to winning on numbers that aren't the point.
Considering you're not playing with real money, experiment with different bets or consult the full rules.

Mathematically speaking, there is no bet where you even technically have a 50/50 chance of winning or losing against the casino. Every single bet has a casino edge built in. In the long term, the house always wins. That doesn't mean you shouldn't play because you'll always lose, But more knowing when to walk away when the dice aren't going your way.
Here, though, if you lose it all, you can just reset your bank! In real life? Not so much.

The goal of the game of Craps is to successfully place bets on the outcome of the dice.
Some bets are only one time rolls while others stay on the table until specific win or loss conditions are met. Most bets are allowed to be placed at any time, while others can only be made at certain times.

Craps is played in rounds, revolving around the 'point' being 'on' or 'off'. At the beginning of a round, the point is 'off'. The rolling player rolls the dice until they roll a 4, 5, 6, 8, 9 or 10. This results in the 'point' being set and turned 'on'. At a real table, the player to the left goes next. You can choose to not roll if you want.

Available only before a point is set, the Pass Line and Don't Pass Line allow players a single way to play 'with' or 'against' the table. Once a point is set, the bet cannot be removed and must either win or lose.

Both pay one for one, with their difference being they are (mostly) complete opposites.

The Pass Line wins on 7 and 11 and loses on 2, 3 and 12 before the point is set, and then wins when the point is rolled again before a 7 is rolled.

The Don't Pass Line is mostly the opposite, winning on 2 and 3, pushing on 12 and losing when a 7 or 11 is rolled before the point is set, and then winning when a 7 is rolled before the point is rolled again. The only thing that keeps them from being true opposites is that the 12 pushes when it's hit before the point is set.

Available only after a point is set, the Come and Don't Come bets are a mini game within the game and, like the Pass Line and Don't Pass Line, they work as (mostly) opposites of each other.

The Come wins on 7 or 11, loses on 2, 3 or 12 and for any other number, the bet moves up to that number. Once moved to a number, the bet cannot be removed and wins when that number is hit before a 7 is rolled. As you can see, it's a mini-version of the Pass Line.

The Don't Come loses on 7 or 11, wins on 2 or 3 and pushes on 12. For any other number, it moves over to that number, losing when that number is hit and winning on the 7. Like the Come, it's a mini-version of the Don't Pass Line.

The Pass Line, Don't Pass Line,Come and Don't Come all allow you to place an Odds bet once a point is set. The amount you can wager for Odds are multiples of your original bet.

For example, if your Pass Line bet was $15, the Odds bet would be in multiples of 15, meaning you could bet $15, $30, $45 etc...

Odds payouts are based on the real odds, meaning the actual odds the roll will happen versus not.

The Place, Lay and Buy bets are available at any time and are directly above and below the point numbers. They are direct bets that the number of choice will (or won't) roll before the 7.
You can remove this bet at any time.

Place

The Place bet allows you to wager that the number will roll before the 7. By default, they are 'off', meaning they are not in play when the point is being set and thus you cannot win or lose on 'come out' rolls. They can be turned 'on' or 'off' at any time.

You can turn them 'on' by toggling the 'Always On?' option that appears on the Bet Menu

Place 4 and 10 pays 9 for 5.
Place 5 and 9 pays 7 for 5.
Place 6 and 8 pays 7 for 6.

Lay

The Lay bet is the opposite of the Place bet in that it allows you to wager that the number won't roll before the 7. These are always 'off', meaning they are not in play when the point is being set and thus you cannot win or lose on 'come out' rolls. Additionally, they must pay a %5 vig, or commission, to the casino when they win.

Lay 4 and 10 pays 1 for 2 - 5%.
Lay 5 and 9 pays 2 for 3 - 5%.
Lay 6 and 8 pays 5 for 6 - 5%.

Buy

The Buy bet is available only on the 4 and 10 and works almost like the Place, except the payout is different and the bet is always 'off'. Additionally, they must pay a %5 vig, or commission, to the casino when they win. The payout for the Buy is technically better than the Place, but cannot be turned off, and thus cannot be considered a strictly better or worse bet.

Buy 4 and 10 pays 2 for 1 - 5%.

Available anytime, these single roll bets come in a variety of payouts but all are direct bets on the very next roll of the dice.
They either win or lose on the next roll.

Field

The Field bet wins on the 2, 3, 4, 9, 10, 11 and 12, with the 2 paying twice your bet and the 12 paying 3 times your bet.

The 3, 4, 9, 10 and 11 pay 1 for 1.
The 2 pays 2 for 1 and the 12 pays 3 for 1.

Hops

Every dice pair has a Hops bet available somewhere on the table. Most are found on the upper right, while the 2, 3, 11 and 12 are found within the Horn.

Mismatched pairs all pay 15 for 1, while matched pairs pay 30 for 1.

Horn

The Horn is a quick way of betting on the 2, 3, 11 and 12 Hops bet. By clicking on the Horn area, the game allows you to bet a specific amount that is then equally divided among the four numbers. As a reminder, 3 and 11 pay 15 for 1, while 2 and 12 pay 30 for 1.

E

The E bet is the Eleven bet. It wins on the, well, 11!

E pays 15 for 1.

C or Any Craps

The C or Any Craps bet is the Craps bet. It wins on the 2, 3 and 12.

C or Any Craps pays 7 for 1.

Any Seven

The Any Seven bet wins on any 7.

Any Seven pays 4 for 1.

The Hardways are bets that the 'Hard' way of the number, meaning the dice are the same number, will roll before the 7 or 'Soft' way, meaning a mismatched dice amount.

For example, the 'Hardway 8' wins when a pair of 4's are rolled before a 7 or any other combination that equals 8 but isn't a pair of 4's.

The 'Hardway 6' and 'Hardway 8' pay 10 for 1
The 'Hardway 4' and 'Hardway 10' pay 8 for 1.
