Twenty One

What is Twenty One?

At its heart, Demon Beats uses the familiar Avalanche mechanic, where winning symbols clear and get replaced by new ones until no further wins appear. That cascade ties into a climbing multiplier ladder; the ladder resets on empty spins and steps up to far higher values once free spins begin.

The more distinctive layer is the game’s use of 2×2 colossal symbols and a Battle feature, in which colossal and Wild symbols land to cover a Battle symbol after a non-winning spin. These additions don’t reinvent NetEnt’s math. They extend the cascade model with bigger blocks and a triggered mini-sequence, keeping the release familiar to players who know the studio’s earlier Avalanche games.

NetEnt also attaches its Elevate suite of paid bonus-entry and feature-boost options

Greg Abel took over as CEO of the $1 trillion organization in early 2026. While Buffett continued to visit the office daily, he indicated he is now ready for a slower pace.

“Recently, I celebrated my 96th birthday with family and friends, including one of my great-grandchildren, who had just turned one. He’s moving a bit faster than I am these days,” Buffett wrote in a letter to shareholders. The billionaire credited Abel with exceeding his “sky-high” expectations, giving him complete confidence in completing the transition.

“The timing is right. I will become chairman emeritus and remain a director. My son, Howard, will succeed me as chairman,” Buffett told investors. “The company is in excellent hands, and I look forward to remaining a shareholder alongside you.”

There have been many uplifting elements to writing about poker through a global pandemic, as odd as those words must feel to read and certainly are to write. From inspirational quotes to motivate players who are just joining or continue to love the game to what could help players turn pro as an alternative to more difficult careers to sustain (they do exist!), it has genuinely been a job I have treasured and I hope you have enjoyed the content that I and the incredible Calvin Ayre content team have been able to bring you during the past 18 months or so.  

Bringing you series of articles such as Poker on Screen and Poker in Print has been a massive source of pride for myself and the team and I even got the chance to discuss poker in the movies and on television on the recent episode of the award-winning podcast, The Chip Race.  

As ever, I am indebted to too many people to mention, but Derek, Bill, Jasmine and every one of the Calvin Ayre team, as well as Calvin himself of course, have all shown a lot of faith in me to carry the torch and I hope I’ve done them all credit.
