Orbis OpenBet is a small software provider that offers flash casino games. They seem to specialize in unique instant win games, like in the screenshot above. However, they also offer blackjack and other common table games. Graphics are solid, but game quality is weak. Games are often slow, even when the "turbo" option is selected. Casinos rarely offer the full suite of possible Orbis games. Instead a small portion may be used, and games may be mixed with another software. For example, Mecca Games uses Orbis for their table games and Wagerworks for their slot games. The Orbis customer list includes many well known and large casinos like Ladbrokes, VC, Sky Bet, Blue SQ, Centrebet, and Totesport. Most customers only use Orbis for their "Games" tab (not the main "Casino"), which may not offer a bonus. The casinos offering a bonus that can be played with Orbis software are listed towards the bottom of this page. All of these casinos are reputable. Orbis software is known to have software bugs. See the Orbis warning for more information.


Game Selection & House Edge

Games selection varies widely from one Orbis casino to the next. The table below lists the games that may be available and the corresponding default house edge. I believe some house options are configurable, such as the number of decks in blackjack and the paytable in video poker. Most casinos seem to use the default values listed below.

Group -- Casinos often are linked together in e group. These groups are listed in the table. I recommend not simultaneously playing two sign up bonuses from the same group. Wait until payment is received, then play at the next casino.

Bonus EV -- EV stands for Expected Value. Bonus EV indicates the average expected gain of the bonus with the following play: Cashable and Post-wager bonuses -- Playthrough the bonus on the listed game with unlimited banrkoll; Sticky and Clearplay bonuses -- Make high variance bets to a 2x target, then playthrough bonus; Free Play and Unique bonuses -- See the listed strategy.

Max Bonus -- The bonus that is given with the maximum allowed deposit for that bonus. If the max value is expressed as one number + another, then there are two bonuses, usually one signup bonus and one deposit method bonus. If the value is expressed as a range, then the bonus is dependent on return from a free play offer.

Bonus % -- Bonus % indicates the ratio between the bonus and your deposit. If a $300 bonus is given on a $100 deposit, the bonus % is 300%.

Wager -- Wager indicates the wagering requirement for the bonus. All wagering requirements are expressed in terms of the bonus. For example, the wagering requirement at Golden Palace is 20x(bonus+deposit). With a $100 deposit, the wagering requirement would be ($300 + $100)x20 = $8000. $8000 is 27x the $300 bonus, so the value in the table is 27xB. Clearplay bonuses may list two wagering requirements -- the minimum wagering requirement and the wagering requirement on the game French Roulette. "0xB / 60xB" indicates that you can cash out your winnings immediately (0xB), and if you complete the playthrough on French Roulette there is a 60xB wagering requirement.

Type -- Cashable bonuses are given at the start of wagering and become withdrawable after completing wagering. Like cashable bonuses, post-wager bonuses are withdrawable after completing wagering. However, they are not given until completing wagering. Sticky bonuses can be bet, but cannot be cashed out. Clearplay bonuses are a special type of cashable bonus offered by many Microgaming casinos games are weighted at different percentages and bonuses are gradually converted to cash while completing wagering. Free play bonuses involve play without making a deposit. After finishing the free play, winnings are credited as a bonus. Unique bonuses have unique rules and do not fit in any of the categories above.

Game -- Game indicates the recommended game to play the bonus.

Notes -- Notes indicates other important things to take note of, such as associated warnings.
