The Top Online Slots Sites for You

Best Proprietary Slots online

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.

Overview of Proprietary Slots

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.
