On the American table this button is disabled. When you click on the Announces button a bet selection window appears. The left half of this window contains a list of special bets to select from, such as orphans, tiers, finals etc. When you select one of these, you will see in the bottom line which numbers are covered by this bet. The right half of the Announces window selects the neighbors .
Neighbors are numbers placed next to each other on the wheel.
If you think that a particular portion of the wheel is more likely to win than another, you can bet on a number and up to four of its neighbors. You may notice that your account balance does not change when you place a chip on the table. The wheel will then stop and a close-up picture of the winning area of the wheel will be displayed. The winning number also appears in the numbers display in the upper left corner and the dealer announces the winning number. It first checks the validity of the message to make sure that no-one is trying to access the server without a valid login access.
