Disclaimer
Casino offers have variance, meaning you’ll sometimes lose money. You have a statistical advantage when completing casino offers. Over time, you should make a profit equivalent to the EV of an offer.
Outplayed usually warns its users if they encounter scammy casino sites. However, you’re still responsible for your sign-up. Always read reviews about a casino before you sign up.

Guides and Offers on Outplayed Diamond

Once you upgrade to Diamond membership, you can see the casino section. Outplayed Diamond plan requires no previous knowledge of sports or casino offers. In addition to the sports tutorials, Diamond provides guides for casino offers.
Offers

Currently, there are 65 sportsbook sign-up offers and 157 casino sign-up offers. For existing customers, there are 141 reload offers. The casino offers are exclusive to the Diamond and Pro plan.
The casino reload offers are part of the daily offers calendar, so it is easy to miss them. Although plenty of filters exist, you cannot separate sports and casino offers.
The instructions let you complete a casino offer even if you have never done one. You will know how much to deposit, which slot to use, how much to stake, etc.
Casino Software
With Outplayed Diamond, you get access to dedicated casino software. These tools help you to complete casino offers and maximise your profit.
1. Blackjack Calculator
The blackjack calculator helps you play blackjack. Because blackjack has such a high RTP, it should always be your game of choice.
With the blackjack calculator, you enter the dealer’s and your cards. The calculator tells you what to do (double, hit, stand or surrender if allowed). You can adjust the dealer’s behaviour to stand or hit at soft 17.
Traditionally, casino players use a simple blackjack chart. However, charts can be hard to read for beginners. This is why you may want to use the blackjack calculator instead.
2. Simulator

The simulator allows you to complete an offer in theory. You won’t lose anything but gain insight into an offer’s risk and potential profit. Enter the details of a given offer into the simulator, and it analyses the offer so you know the:
- Estimated value
- Bust rate (risk of losing everything)
- Average time to complete the offer
- Cash per hour (this is a theoretical value)
- Amount wagered
3. Slots Database
With the slots database, you can quickly discover an offer’s return-to-player (RTP). This tells you which slot is the most profitable. You can also see the slot’s variance, allowing you to avoid high-variance slots.
How to Switch to Diamond Membership
Platinum to Diamond Plan
If you use Outplayed Platinum and wish to upgrade to Outplayed Diamond, you can do so anytime. For those on a monthly payment plan, wait till the end of the month and upgrade. Or you can upgrade at any other time and pay a pro-rata charge.
If you are on an annual plan, you can also upgrade to Diamond anytime. You’ll only need to pay the difference between Platinum and Diamond.
For example, I use Outplayed Platinum. If I want to upgrade to Outplayed Diamond, the following message appears:

Instead of paying the full price for a Diamond membership, I only need to pay £125.34, which is the cost for the rest of my year. Then, I can pay the total price once the original year is over.
In case anyone is doing the maths: I paid £150 for Outplayed Platinum because I signed up during a promotion.
Bonus Accumulator to Outplayed Diamond
If you are with Bonus Accumulator and want to use Outplayed Diamond, contact Outplayed’s customer support. They may be able to help you switch before your billing period is over.
OddsMonkey All-Access to Outplayed Diamond
OddsMonkey has offered discounts to users switching from Outplayed to them. Thus, Outplayed might do the same. It may not work, but it’s worth asking customer support before you switch.
