Inside bets: Straight, split, trio, street, first four, corner, basket and six line bets.

A straight, or single, bet is a bet on a single number. On a real roulette table you would place your chips on the square which contains the number, on our roulette table you type the bet amount in the box immediately under the number. In the below picture we have shown two sample straight bets: 2 $ bet on 0 and 2 $ bet on 4.

A split bet is a bet on two adjacent numbers. On a real roulette table you would place your chips on the line between the two numbers, on our roulette table you type the bet amount in the box between the two numbers. In the below picture, for the European roulette layout, we have shown two sample split bets: 5 $ bet on 1-2 and 5 $ bet on 3-6. In the below picture, for the American roulette layout, we have shown two sample split bets: 5 $ bet on 0-00 and 5 $ bet on 0-1.

A trio bet is a bet on three adjacent numbers which include 0. On a real roulette table you would place your chips on the corner between the three numbers, on our roulette table you type the bet amount in the box, inside the darker bordered cell, between the three numbers. In the below pictures, for the single zero roulette layout, we have shown a sample trio bet: 10 $ bet on 0-2-3 (the remaining trio bet on a single zero roulette is 0-1-2). In the below picture, for the double zero roulette layout, we have shown a sample trio bet: 10 $ bet on 00-2-3 (the remaining trio bet on a double zero roulette is 0-1-2).

A street bet is a bet on three consecutive numbers in one of the 12 rows. On a real roulette table you would place your chips on the line at either end of the row, on our roulette table you type the bet amount in the "Str." box at the top end of the row. In the below picture we have shown a sample street bet: 15 $ bet on 4-5-6.

The first four bet is the bet on 0-1-2-3, available only in the European Roulette or single zero roulette layout. On a real roulette table you would place your chips on the outer corner between 0-1 or 0-3, on our roulette table you type the bet amount in the "1st 4" box at the top left end of our roulette table. In the below picture we have shown the sample 1st four bet: 20 $ bet on 0-1-2-3.

Table 1 - Explanatory notes:

1) The single zero roulette layout (European or French) has a total of 37 numbers, which is 1 to 36 and 0. The double zero roulette layout (American) has a total of 38 numbers, which is 1 to 36, 0 and 00.

The win probability on a single zero roulette table is greater than in a double zero roulette table, for a single number bet 1/37 vs 1/38, for a split bet 2/37 vs 2/38 and so on.

2) "Payout" indicates how much you win in bet amounts. Note that, when you win, the bet is returned to you so you collect from table "Payout" + 1 bet amounts.

Examples: Payout 2 - Win 2 times the bet amount, collect 3 times the bet amount; Payout 11 - Win 11 times the bet amount collect 12 times the bet amount.

3) The "Expected Value of 100 $ Bet" column is the result of: (100 $) times ("Win Probability") times ("Payout" + 1).

As you can see in the above table, the European Roulette has the same 97.3 value for all bet types. The American Roulette has the same 94.74 value for all bet types except for the "Basket" bet which has a 92.11 value (a worse bet than the others). The European Roulette has a greater expected bet value than the American Roulette.

Consider that the mentioned values are average values. For a finite, although large, number of bets, the actual value could be very far from the expected value.

4) Another way of reading the "Expected Value of 100 $ Bet" (assuming the European roulette case):

If you kept playing roulette for an infinite number of times, the cumulative money collected from table would become closer to 97.3% of your cumulative bets while the cumulative money lost would become closer to 2.7% of your cumulative bets.

Not a suggestion to try and see how it works, 2.7% of an infinite number of bets is too much money to lose. Well before that, losses will make you stop playing and force you to retire from the experiment.

5) With roulette the odds are always against you.

If you are lucky with one or few bets then walk out of the casino and never play again, you have won.

If you keep playing, you know what the odds are and what's likely going to happen.

6) Here is some interesting reading from Wikipedia: Law of large numbers; Gambler's fallacy.

7) You can play with our European roulette simulator and American roulette simulator without any risk of losing (or winning!) real money.
