Dozens bets are placing your chips on the 12 consecutive numbers. As most top online casinos, these bets have a 2:1 payout. Boxes marked as 1-12, 13-24 and 25-36 are your three possible bets but, if the ball lands on zero or double zero the players loses to the house. As seen on many UK online gambling, column bet is also a 12 number bet like the dozens bet. Instead of twelve consecutive numbers, the player places his bet in one of the three vertical columns. The wagers are selected in the boxes at the layout's bottom. It has a 2:1 payout.
