2021 is finally here and not a day too soon.  Thank God for that!

While the coronavirus pandemic has wreaked havoc throughout the world's economies dating back to last March, online casinos are among the rare success stories along with the likes of Uber Eats and video conferencing.  Because land-based casinos were mostly shuttered, folks resorted to playing online from home in their pajamas.  Even after casinos in Vegas began opening, Covid-19 outbreaks at casinos were evident and ensured more gamblers remained home.  Global shutdowns often translated into boredom and the discovery of Web-based casinos, many of which feature live dealers and an immersive land-based casino environment.

Slot suppliers like YggdrasilCasino.com were quick to capitalize with a focus on superior design and gaming innovations and competitive promotions.

Yggdrasil has long pushed the boundaries when it comes to design. As an example of this, their Jungle Books slots not only features living symbols but an entire world of creatures and characters outside of the reels.

The company was named "Innovator of the Year" at the 2019 International Gaming Awards.

From the depth of the ocean, Sirens attempt to stop you matching three or more symbols and banking prizes worth up to 250X your bet. Fortunately, you’ve got one thing on your side: Rage. You see, the cornerstone of crazy is its ability to switch in a second. One minute, the sea is calm and you’re casually spinning five reels.
