Easy bonus clearing with $540 EV at Mansion Keno (after Steelers bet)

[EC Mount]

If your first deposit at Mansion was $1100 to the the Steelers bet, then you also were given an $1100 bonus that can be played off in the casino or poker room. In the casino you must wager 10x the bonus+deposit. In this case, total wagering of $22,000 is required (($1100+$1100) *10)

This is further complicated by the fact that certain games have reduced contribution to the required wager. For instance, blackjack only contributes 10% of each bet towards your wagering requirement. So, a $5 bet on blackjack only contributes $.50 cents towards your $22,000 requirement. Baccarat contributes 25% towards your wagering requirement and results in about $150 EV if played out.


However, the best way to clear this bonus is actually with KENO resulting in EV of $540.08! Keno clears at 100% contribution for each bet. So a $10 bet at keno clears $10 of your wagering requirement. They allow this because Keno has a much higher house edge than most other games, however it seems they overlooked a keno side bet they offer.

Mansion offers a odd/even side bet on Keno that pays 1.95:1. (2.5% house edge) In order to play this bet, you have to also pick numbers. Picking 3 numbers has a house edge of 6.962%. Mansion allows your side bet to be 100x larger than your number pick bet. So, you can bet $.10 cents on the 3pick and $10.00 on the side bet.

This will require 2179 total spins to clear the $22,000 wagering requirement. The total expected house edge on this is $559.92 leaving your expected bonus EV of $540.08.

Doing this manually would be tedious, but setting up a script to auto-run these spins is not difficult and results in an easy EV $540.


I've not calculated the SD or risk of ruin, but it should be relatively insignificant. Anyone want to add those calcs to this discussion?

Was this bonus already credited or only after wagering? When I go into a casino game, I only see my original, cashable balance.

If you click "My Account" and then the "Earned Bonus" tab you will see where the bonus is calculated. It is already available to you (if this was your first deposit) - it just needs to be cleared.

Pretty sure it's not credited until you meet the WR.

and OP, I don't have time to run through your math, but if correct, NICE WORK!

I think this needs more investigation. Keno itself can have very high variance. Not sure about the side bet you're talking about though.

[EC Mount]

Right, most of the money is bet on the side bet which will have very low variance over 2179 spins.

The 3pick will have higher variance, but is much less significant.

What is the SD of the side bet? Do you know? How do we find out?

One more point:

You don't really need a script to automate this. They have a "Play 10x" button which runs 10 spins for you. It's not tough to leave this up on a second monitor and press the 10spin button every 5 minutes or so while working on something else.

(I know some people are not comfortable with AHK scripts)

220 presses of that button and you are EV $540 richer.

Have u tried clearing it or is this just a theory?
