TYPES OF BETS

THE NUMBERS 1 TO 36 SIGNIFY A STRAIGHT BET
ON THAT NUMBER.
THESE PAY OFF 35:1

THE 2:1 BETS ARE:
37) 1-12     40) FIRST COLUMN
38) 13-24    41) SECOND COLUMN
39) 25-36    42) THIRD COLUMN

THE EVEN MONEY BETS ARE:
43) 1-18     46) ODD
44) 19-36    47) RED
45) EVEN     48) BLACK

 49)0 AND 50)00 PAY OFF 35:1
NOTE: 0 AND 00 DO NOT COUNT UNDER ANY
   BETS EXCEPT THEIR OWN.

WHEN I ASK FOR EACH BET, TYPE THE NUMBER
AND THE AMOUNT, SEPARATED BY A COMMA.
FOR EXAMPLE: TO BET $500 ON BLACK, TYPE 48,500
WHEN I ASK FOR A BET.

THE MINIMUM BET IS $5, THE MAXIMUM IS $500.
