Proprietary Play Slots and Casinos

Proprietary slots can add to the appeal of a specific online casino. The operators tend to put a lot of work into their unique creations to ensure they enhance the reputation of the company, so proprietary slots are well worth trying out. Our current favorite three proprietary slots are:

1. Millionaire Genie - 888 is one of the biggest developers of proprietary games. The famous online casino and poker operator has a collection of unique slots that have been developed in-house. Millionaire Genie is an example of its best work, and it has a progressive jackpot that can exceed $1 million!
2. Alice in Wonderland - There are quite a few slots based on the story of Alice in Wonderland, but this version was developed exclusively by Slotland for its online casino. It has a vibrant theme with an impressive level of detail, and bonus features include free spins with multiplied payouts.
3. 3 Golden Wishes - 3 Golden Wishes is a fresh new release from mFortune that can be found exclusively on its casino network. The operator has developed quite a few proprietary slots over the years, but this one is a stand-out for its great visuals and bonus features, including free spins with multipliers.

Our reviews team carried out a series of tests on a large cohort of online casinos that offer Proprietary games. We only recommend casinos after vetting them in the following areas and ensuring they meet our strict criteria:

• Security and licensing - We check that the casinos are properly licensed and regulated, have the eCogra stamp of approval, and use SSL-encryption.
• Games - We play the games ourselves to check their quality, speed, and features. We also like to see a wide range of slots, and plenty of other casino games on offer in case players would like a break from the reels.
• Payment methods - We ensure that the casino accepts a variety of payment methods and that the deposit and withdrawal process is quick and easy.
  
• Customer support - We get in touch with customer support to assess the speed and efficiency of the response.
• Bonuses - We look for sizeable welcome bonuses without huge wagering requirements and scout out worthwhile VIP and loyalty schemes.

Given the fact that proprietary slots are quite rare, we recommend playing for free in demo mode to decide whether you want to bet real money. We recommend the following free proprietary slots for their iconic themes and rewarding bonus features:

• 3 Golden Wishes
• Alice in Wonderland
• Sherlock: Murdered to Death
• Rise of the Pharaohs
• Cirque De Paris

Betting real money is the best way to increase the entertainment value and have the chance of winning big payouts. Proprietary games can come with special bonuses and promotions when betting cash at trusted casinos online, and our top-rated real money proprietary slots include:

• Millionaire Genie
• Dragon's Lair
• Cat & Mouse
• Treasure Fair
• Irish Riches

Proprietary slot software differs depending on the creator, so it’s difficult to review the mobile gaming optimization of these kinds of slots. However, we can safely say that most of the new proprietary slots launched online are available on mobile devices. The best casino software developers provide great mobile compatibility, often in HTML5, which means the game will load instantly in your web browser, with no downloads necessary.

Proprietary games are becoming more popular with large operators. Some sites can offer exclusive live dealer tables for a more familiar environment. Exclusive slots aren’t uncommon, but they’re often developed by established slot game providers for one particular casino. Proprietary is not always exclusive, as some casinos can also have games from other online slot providers along with their unique creations.
