AUSTIN, Texas, Oct. 15, 2026 /PRNewswire/ — Lucid Poker, the mobile-first poker training app founded by heads-up poker legend Doug Polk, today launched Cardle on the web. The free daily poker quiz is now open to anyone at cardle.poker, with no sign-up or download needed.
Each Cardle spot is hand-picked and built by Polk himself, mixing bluffs, spots that look like bluffs but are actually checks, different sizings for value and a real range of decisions that get your mind working. After every hand, players get a short, clear breakdown of the decision, showing not just the raw solver output but what Doug recommends. It’s the Wordle for poker.
From a $1.2 million poker grudge match to an app on your phone
When Polk took on Daniel Negreanu in the “High Stakes Feud,” he was up against one of the most successful poker players of all time: a Poker Hall of Famer, eight-time World Series of Poker bracelet winner, two-time WSOP Player of the Year and a player with over $57 million in live tournament earnings. It could have been an absolute dismantling.
Instead, Polk won. Decisively. Over three months and more than 25,000 hands of $200/$400 no-limit hold’em, running from late 2020 to February 2021, he finished roughly $1.2 million ahead in one of the most-watched poker rivalries of the modern era.
His edge came from the same thing that had served him his entire career: relentless, structured study and deep preparation for his opponent. The tool at the heart of that preparation was Lucid Poker.
“Beating Daniel took months of preparation and a level of study most players never get access to. When I built Lucid, the goal was simple: put that same ability to train and study in the hands of anyone with a phone. You shouldn’t need to be a full-time pro to train like one,” said Doug Polk, founder of Lucid Poker.
Poker training, reimagined for the modern game
Most poker training tools are intimidating, clunky and stuck on desktop. Lucid flips that. It’s built mobile-first for new and experienced players alike, and study feels fast and rewarding.
Standout features include:
- The Daily Cardle, a daily poker puzzle that turns sharp decision-making into a simple, addictive habit
- Intuitive, mobile-first design, with none of the friction of traditional solver software
- Instant Decision Ratings, with every decision rated Best, Good, Inaccuracy, Mistake or Blunder
- 100+ million solved hands across cash, tournaments, Spin & Go and HU SNG
- EV and equity heat maps for postflop analysis
- Custom re-solving and a built-in solver
- Native apps for Android, Windows, macOS and iOS
Lucid already has over 10,000 players training on the app and almost 1,000 Daily Cardles to play. And this is just the start. Lucid’s roadmap includes deeper simulation tools, expanded game formats and Blitz Poker, a quick, gamified way to play and learn poker with power-ups and more.
Why now
Poker has never been more driven by data, solvers and AI. The game is tougher than ever, but the tools behind that level of play have stayed locked inside complex desktop software built for professionals. Lucid’s mission is to change that, taking the tools that win million-dollar heads-up matches and making them accessible to every poker player.
“Doug proved what study and preparation can do in poker when the stakes are highest. What excites us about Lucid is taking that same approach and handing it to everyone. We all spend hours a day scrolling on our phones. Lucid replaces the scrolling with five minutes that make you a better poker player. We’re building the training platform we wish existed when we started playing, and we’re only just getting started,” said Mike Brady, CEO of Lucid Poker.
