Online Casino Game Rules

Diamond Bet Roulette

Exciting new betting options

The aim of playing Diamond Bet Roulette is to place bets on where the ball will land on the roulette wheel. This online roulette game uses 38 slots on the wheel, 0-36 plus a Diamond position. Bets on the Diamond Position can pay up to 100x your stake.

This game uses standard European rules.

Getting Started:

Choose your table limits from the welcome screen. Select Join to go to the roulette table.

  • Click on a chip to select it from the panel on the left-hand side of the screen.
  • Place the chip (by clicking again) on the part of the betting table you wish to bet on. Another click will place another chip of the same value. You can repeat the process with different valued chips if you like.
  • Press Undo to remove the chip that was last placed on the table. Press Clear Bets to remove all chips from the table and start over.
  • Press Double to instantly double all bets.

Note: you can place as many chips on as many different betting options as you like. However, you must stay within the betting limits selected on entry to the game.

How to Play:

  • Press Spin when you have made your betting selections.

The ball will be released on to the roulette wheel. As the ball spins, the sections of the outer wheel will light up in consecutive stages. Eventually, the ball will come to rest on one of the slots and one section of the outer wheel will be lit. Winning bets will be declared and you will be given the following options:

  • Rebet = start a new round with the same bets as the previous round. You will be given the opportunity to adjust bets if you wish.
  • Rebet & Spin = make the same bets as the last round and spin the wheel.
  • Double & Spin = double the previous round’s bets and spin the wheel.

Diamond Bet:

The outer wheel is used for the Diamond Bet. it is made up of sections, each showing a Multiplier or Jackpot. The Multipliers, ranging from X15 to X50, will be the payout award for a winning Diamond Bet. If the Jackpot section is lit, it will award winning Diamond Bets the maximum payout of 100 X the bet.

Auto Play:

If you hold down the spin button with your cursor, it will open the Auto Play feature. This will allow you to set 10-99 game rounds to be played consecutively with the same bets.

Press the Stop Auto Play button to exit at any time.

Table Layout and Features:

The chip selection panel is located on the left-hand side of the screen. You can scroll the panel to access different chip values.

The game buttons are displayed on the right-hand side of the screen. These buttons can change, depending on which stage of the game you are currently playing.

The betting table takes up the lower half of the centre of the screen.

The top half of the screen holds the roulette wheel, a zoom view of the wheel, the history panel and the racetrack.

Note: a display beside the history panel detail the number of spins since the Diamond Bet has been won.


Click on the racetrack to replace the betting table with the racetrack view. You can switch back again in the same manner.

The racetrack will display the numbers as they appear on the wheel, rather than numerically like the betting table. It will allow you to quickly place special betting patterns, including Neighbours, Orphelins and Tiers.


Neighbours Bets allow you to choose a number and also bet on the numbers directly adjacent to it on the wheel. You can choose 1-5 Neighbours, i.e. 1-5 numbers either side of your selection.

For example, choosing 17 with 3 neighbours would place a chip on 27, 6, 34, 17, 25, 2 and 21.  

Note: You can place combinations of Neighbours Bets if you wish.

Voisins Du Zero:

Clicking on Voisins Du Zero places chips on the 17 numbers surrounding – and including – Zero. It covers around 45% of potential outcomes. 9 chips are used for the Voisins Du Zero bet.


Clicking in Tiers places chips on the 13 numbers opposite Zero. It covers around 34% of potential outcomes. 7 chips are used for the Tiers bet.

Note: the Diamond Bet is covered in the Tiers bet.


Clicking on Orphelins will place chips on the eight numbers not covered by the Tiers and Voisins Du Zero bets. It covers the remaining 21% of potential outcomes. 5 chips are used for the Orphelins bet.
