Online Casino Game Rules

101 Roulette

The roulette wheel has 105 slots

101 Roulette is a simple casino game based on the classic game of roulette. However, this version uses a bigger, oblong track that is made up of 105 slots – 100 numbers, Zero and 4 Suits. The payouts are much bigger than traditional online roulette games, but the basic strategy remains the same.

The main objective is to place bets on where you think the ball will land on the roulette wheel/track.

Getting Started:

A range of chips is displayed in the horizontal belt on the left-hand side of the screen:

  • Select a chip value by clicking on it, then click again on the relevant part of the betting table. Each click – anywhere on the table – will add another chip of the same value.
  • Click again on a chip of a different value – if desired – to place different bets.
  • Press Undo to remove the last chip placed on the table.
  • Press Clear Bets to remove all chips and start again.

Note: You can place as many bets as you like, although you must adhere to the maximum and minimum betting limits (displayed on the upper left of the screen).

Note: You can click Double at any time to instantly double all bets on the table.

How to Play:

  • Press Spin to confirm bets and start the game.

The ball will be released on the wheel and come to rest on one of the 105 possible slots. Winnings bets will be highlighted on screen and paid (if applicable) into your balance. After the round is completed, the following options appear on screen:

  • Rebet = start a new round with the same bets on the table as the previous round. You can use the Clear Bets button to remove the chips and start again.
  • Rebet & Spin = start a new round with the same bets as the previous round, confirm and spin the wheel.
  • Double & Spin = double the bets of the previous round, confirm and spin the wheel.

Auto Play:

You can set a number of rounds with the same betting pattern to be played consecutively using Auto Play. To use Auto Play, place your bets as normal and hold down the Spin button. This will open an Auto Play slider which will allow you to set 10+ consecutive rounds with the same bets.

Note: You can exit from Auto Play at any time by clicking Stop Auto Play.

Table Layout and Features:

The top half of the screen holds the roulette track in the centre, a history panel on the right and a zoom-view of the ball on the left.

A coverage panel (located between the betting table and roulette track) will show the percentage coverage of all bets on the table.

The lower half of the screen holds the betting table in the centre, the game buttons on the right and the chip belt on the left. Above the chip belt there are two sliders that will allow you to set these two betting features:

Lucky Number:

This function will allow you to place a bet on all numbers at the border and corners of a selected number. For example, placing a chip on 45 would also bet on 34, 35, 36, 44, 46, 54, 55 and 56.

Quick Bet:

This function will allow you to quickly place a bet on all numbers forming a column and a row of a specific number. For example, placing a chip on 45 would also bet on 5, 15, 25, 35, 55, 65, 75, 85, 95, and 41, 42, 43, 44, 46, 47, 48, 49 and 50.

Note: you can use Quick Bet and Lucky Number at the same time if you want.

Betting Options and Payouts:

There are 105 different possible outcomes for the game. The roulette track features slots with the numbers 1-100, a Zero slot and 4 slots represented by Hearts, Diamonds, Clubs and Spades respectively.

Just like traditional online roulette games, you can place a bet on a single number, sequence of numbers or other outcomes. The table below shows the popular betting patterns and their payouts:
