Guinness World Records Puzzle Master — the only person ever to hold the title. Three decades building the puzzles and cognitive games that reach the world.
In May 2000, Guinness World Records officially recognized Timothy E. Parker as the world's most syndicated puzzle compiler — a distinction that elevated him to the formal title of Guinness World Records Puzzle Master, the only person in history to hold that specific designation. Over a 30-year career his puzzles have reached more than 180 million solvers across 80+ countries.
The legendary creator of Jeopardy! and Wheel of Fortune chose Parker to write every one of the 225 episodes of Merv Griffin's Crosswords. Griffin's verdict was simple:
"America's best puzzle master by far."
For three decades, Parker's work has been trusted by Microsoft, Disney, Warner Bros., Comcast, and the Smithsonian Institution, and featured by People Magazine, CBS News, ABC, Entertainment Tonight, and more. He has authored over 100 books with Simon & Schuster, Penguin Random House, Thomas Nelson, Wiley (For Dummies), and other major houses.
Brain Games Hub brings that lifetime of expertise into a daily training platform. Every one of its 60 games is scored across six brain regions and rolled into a single Brain Score on the same 0–220 scale as Real World IQ — cognitive training designed by the Guinness World Records Puzzle Master himself.
