FOURSURE
September 28, 2026 Puzzle Breakdown
Four groups, four words each — here's the connections between today's words.
How everyone did today
NFL quarterbacks
Allen, Burrow, Jackson, Mahomes
We start off today with the easiest group on the board, provided you follow professional football even a little bit. Allen, Burrow, Jackson, and Mahomes are four of the most prominent starting NFL quarterbacks currently taking snaps on Sunday afternoons. If you spent time looking for US presidents or British actors instead, you overthought the kickoff.
Teenage mutant ninja turtles
Leonardo, Raphael, Donatello, Michelangelo
If you immediately thought of Renaissance masters, you were overcomplicating things. This group was looking for the four sewer-dwelling, pizza-loving Teenage Mutant Ninja Turtles. As the second-easiest set of the day, it only required you to channel your inner Saturday morning cartoon enthusiast.
Units commonly used in electrical engineering
Amp, Ohm, Watt, Hertz
Standard physics terms took the second-hardest slot today, though anyone who has ever looked at the back of an appliance had a fighting chance. Amp, ohm, watt, and hertz all measure various fundamental properties of an electrical circuit, from current and resistance to power and frequency. Hopefully your circuitry did not overheat trying to isolate them from the rest of the board.
Italian inventors
Da vinci, Marconi, Volta, Meucci
Today’s hardest category asked you to look past famous names and focus on a very specific shared heritage. Da Vinci, Marconi, Volta, and Meucci are all Italian inventors credited with pioneering everything from the helicopter and radio to the electric battery and telephone. If you were tempted to sort them purely by science or art, that was entirely by design.
Why these four groups
This board hinges on teasing your Renaissance and scientific trivia instincts before letting you settle. The obvious trap lies in the historical overlap between Leonardo and Da vinci, just as Volta dares you to force a fifth electrical unit into the Amp, Ohm, Watt, and Hertz lineup. However, the difficulty curve holds firm because modern NFL quarterbacks like Mahomes and Burrow give sports fans an immediate clean sweep, while the Ninja Turtles provide an unmistakable pop-culture anchor. That leaves the Italian inventors as the rightful final hurdle, requiring you to separate electrical units from the pioneers who inspired them.
