MICROGAMING CLEARPLAY BONUSES

 

Introduction

Most Microgaming casinos use the Clearplay bonus system, also known as the eZ bonus system. Under traditional implementation all games are allowed, and you can withdraw your winnings at any time, whether you have met the wagering requirements on the bonus or not. Unfortunately, most casino groups now use a modified form of the bonus on their sign-up, with a required playthrough. As you meet the wagering requirements, the the bonus is incrementally converted to cash. This makes the bonus like a sticky bonus with no playthrough, if cashed out early and like a cashable bonus, if wagering is completed.

When completing wagering with small bets, the EV of a Clearplay bonus is usually quite small, sometimes negative. EV can be increased dramatically with large or high variance betting. Average bonus retention might increase from 20% to 80%. This strategy carries a high risk. You may win big, and you may lose your deposit. You can still make a gain at many casinos without higher risk bets. If you have a low risk tolerance, I recommend either making a smaller deposit or playing through the bonus without large bets (see "Playing Through The Bonus") section below. See the two-tier betting page for a more detailed discussion of how EV changes with bet size.

 

Large or High Variance Initial Bets

Imagine a coin flip where you win $200 if it is heads and you lose $100 if it is tails. This is obviously a good deal. The average gain is ($200 - $100) / 2 = $50. A traditional Microgaming Clearplay bonus with a 100% match of $100 can have a similar payout to this coin flip. If you bet all $200 of your balance on a 1:1 bet with no house edge and win, your balance would increase to $400 -- $300 cash and $100 bonus. If you withdrew the $300, your gain is would be $200 after the bonus is removed. If you lost the bet, you would lose $100. Like the coin flip, the average gain for this bet is ($200 - $100) / 2 = $50. If you bet all of it a second time after winning, then 1/4 of the time, you would gain $600 and the other 3/4 of the time, you would lose $100. This increases the expected return to ($600 - 3*$100) / 4 = $75. If you keep betting all your winnings over and over, you approach an average gain near the bonus size. The obvious downside of rebetting over and over is you would typically lose your deposit. Most people would prefer a strategy where they typically win and would forgo some of the expected gain to do so.

As described above, one strategy is to bet your full bankroll on a single hand of a coin flip type game, like baccarat and roulette. French roulette is often a better choice than baccarat if you plan to play through the bonus, since it usually contributes more towards wagering. However, instead of full-bankroll bets, I recommend making half-bankroll bets or less on blackjack. If you keep playing blackjack until you either double your bankroll or bust, then the end result is similar to a full bankroll bet. The EV is slightly higher at a comparable bust risk with half-bankroll bets on blackjack than with full-bankroll bets on baccarat/roulette. There is also a lower risk of being labeled as an advantage player, if you avoid full-bankroll bets. The Casino Rewards group forbids full bankroll bets in their terms, and the Fortune Lounge group has confiscated winnings for using a full-bankroll bet type strategy. Another good alternative is to make smaller bets on a higher variance game like video poker, then double up (using video poker double function) until reaching a target gain. You could even play slots with a similar double up (using slot double function) strategy. There are countless other alternatives. Choose a game, make large or high-variance bets, then stop if you have a large net win.

The table below lists the average gain with a variety of games and strategies. The results assume that you cash out after reaching the target and do not complete wagering. Average gain is expressed as a percentage of the bonus. For example, if you receive a 100% $100 Clearplay bonus and bet all $200 on a baccarat player bet (repeating bet in case of tie), 49.3% of the time you will win the bet and gain $200, and 50.7% of the time you will lose the bet and lose your $100 deposit. So the average gain is $200*.493 - $100*.507 = ~$48. The table lists 48% of the $100 bonus for a full-bankroll baccarat player bet with a 2x target. Use the two-tier bet size simulator simulator to check average gain and bust risk with other strategies.

From the table below, it is clear that average gain follows the chance of busting and losing your deposit. The more the risk, the more the average gain. If the bonus is forfeited and not played through (and for non-cashable bonuses in general), the average gain is:

Average Gain = Bonus * Chance of Bust - Average Wagering * House Edge

Using this equation in the baccarat bet example above: average gain = $100 * .507 - ($100+$100) * 1.4% = ~$48, the same value as listed above. To optimize gain, you want to choose a strategy with a low average wagering * house edge, as well as high risk of busting early in the wagering. Optimal theoretical strategy involves either betting on an extremely unlikely outcome or making sequential full/half bankroll bets. However, few people want a strategy where they lose 90+% of the time. Selecting a chance of busting depends on your individual risk tolerance and bankroll. If you have a high risk tolerance, choose a higher risk of busting. If you have a low risk tolerance, choose a lower risk of busting or play through the bonus without making large bets. I think a good balance is half-bankroll (or less) bets on classic blackjack until 2x bankroll or more. If you avoid making full-bankroll blackjack bets by reducing bet size on losses, then average gain % with classic blackjack is just under chance of bust... nearing optimal strategy for this level of bust risk. If you have a higher risk tolerance, choose a higher target, like 4x bankroll.

Expected bonus retention for a variety of games with this weighting is listed below:

Looking at the table above, the two games with the highest expected gain are French roulette and all aces video poker. While all aces has a lower house edge, I recommend choosing French roulette instead. All aces often has a high minimum bet size for multiplay -- $0.10x5, rather than the usual video poker minimum of $0.01x5. This results in an extremely high variance over such a high wagering requirement. Furthermore, there is no autoplay function, so completing the long wagering will be time consuming. In contrast, French roulette has a much smaller variance and autoplay with quick spin.

If French roulette is weighted under 50%, it is not to your advantage to playthrough the bonus. Instead cash out after a big win, if allowed. Unfortunately many casino groups do not give you the option to cash out after a big win. Instead, you must complete the full playthrough before making a withdrawal. The group names and French roulette weightings are listed on the table at the bottom of this page. In the table, "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.

French roulette has a lower house edge than other variations because of the "la partage" rule. If the ball lands on zero, half of bets on 1-18/19-36, red/black, and even/odd are returned. You can speed up wagering and reduce variance over a wagering requirement by betting on both red & even, or black & odd. The standard deviation per unit wagered of a single 1:1 bet on French roulette is 0.990. The standard deviation per unit wagered of a bets on red & even or black & odd is 0.937. The combination has a slightly lower variance than single 1:1 bets because there are only 8 red & even or black & odd combinations of numbers, less than the expected 36/(2x2) = 9. In contrast, there are 10 red & odd combinations, so betting on red & odd increases standard deviation per unit wagered above single 1:1 bets.

To further minimize risk in French Roulette, you may be tempted to bet on both red & black; or bet $36 on red, $36 on black and $1 on zero (all game results return same value). Some Microgaming casinos have rules against this strategy in their T&C. Others may pay the player as expected, then ban the player from receiving further bonuses. If you have made a big win with a large bet, I strongly recommend against betting on both red & black and giving the casino an excuse not to pay you.

The table at the bottom of this page shows average overall gain with two-tier betting and completing wagering on French roulette.

 

Casino Rewards & MiniVegas Groups

Casino Rewards, MiniVegas, Unibet, and Betway use revised game weightings with reduced weighting for French Roulette. The Casino Rewards group weightings are listed in the table below. Note that there are two changes from the traditional weightings, to eliminate the two EV+ playthrough games mentioned in the section above -- French roulette and all aces.

Expected bonus retention for a variety of games with these weightings are listed below:

In my opinion, 3 Card Poker: Ante & Play, Casino War, and Vegas Strip Blackjack are the best choices for completing a wagering requirement with these weightings. The house edge of 3 card poker: ante & play is 3.37% under Microgaming's rules. House edge is defined as the average loss per initial bet. However, in 3 card poker the final bet size may be larger than the initial bet. The average loss per unit wagered is 2.01%. This value is more appropriate than house edge for calculating expected loss while completing the 60xB required wagering. The average loss per unit wagered of casino war is 2.17% under Microgaming's improved rules. 3 card poker has a slightly lower expected loss than war, while war has a lower variance than 3 card poker. Vegas strip blackjack is also a good option when autoplay is allowed. However, the Casino Rewards group restricts autoplay in their terms, and without autoplay a 300xB wagering requirement is not practical.

Note that doubling your balance with full bankroll bets is also restricted under the Casino Rewards terms. Instead I recommend quarter bankroll or less bets on blackjack / 3 card poker / casino war until you either reach a target gain or bust, then switching to smaller bets after reaching the target. The table at the bottom of this page shows average overall gain with two-tier betting and completing wagering on 3-card poker with 50% weighting.

 

Vegas Partner & Golden Star Groups

The Vegas Partner group, the Golden Star group, and the Playshare group have a required playthrough and low game weighting similar to the table below. This makes the bonus much less desirable and results in a different strategy. The Vegas Partner & Golden Star group's game weighting is listed below.

Expected bonus retention for a variety of games with this system is listed below:

You are expected to make a loss while playing through the bonus on all games except for all aces. Unfortunately, the large wagering requirement and high variance makse playing through the bonus on all aces impractical, so I recommend French roulette instead, in spite of the poor weighting. You can make up for this loss while playing through by making large bets and setting a higher target than usual. The table at the bottom of this page lists average overall gain with 25% French roulette weighting (120xB French roulette wagering). Note that you can still retain the majority of the bonus with a high-risk strategy, such as classic blackjack to a 4x target.

 

Other Groups

A summary of rules by group is in the table below. Globet, Intertops, Jackpot Factory group, Palace group, Roxy / Splendido group, and Unibet use traditional weightings with French roulette at 50%. Fortune Lounge group has a slight change to traditional weightings reducing French Roulette to 40%. Betway, Casino Rewards group, and MiniVegas group have more severe changes to French roulette weighting, but still have 50% table game weightings. Golden Star group, Grand Prive group, Playshare group, Vegas Partner group, and Villento have poor weightings for both French roulette and table games.

 

Average Overall Gain

The table below shows the average overall gain with a 100% Clearplay bonus for a variety of strategies, with the four game weightings discussed above -- 0xB wagering (cash out early), 60xB wagering on French roulette (traditional weighting), 60xB wagering on 3-Card Poker (Casino Rewards & Mini Vegas), and 120xB wagering on French Roulette (Vegas Partner & Golden Star).
