The following list contains all the logic gate puzzles I published so far.
I created a logic-gate puzzle featuring a gated D latch: more artwork than optimized circuitry. I invite you to try decoding the hidden message—there are hints and links to gate and flip-flop basics in the post. I hope you enjoy the challenge; read the full article if you'd like to solve it.
I uncovered an ancient stone with a mysterious multiplexed display — five inputs and six outputs. In this puzzle I explore what the display likely represents and invite you to find the longest continuous sequence of numbers it can show. Try the interactive panel and read the full post to solve it.
I present a symmetric logic-gate circuit that implements a well-known function. Try to identify the function; hints are provided if you get stuck. If you enjoy this kind of puzzle, read the full post for images, tips, and the solution - I'd love your feedback and suggestions for more puzzles.
I present a stylised logic-gate puzzle: a circuit that performs a handy function. Try to deduce what it does from the diagram, use the hints if you get stuck, and read the full post for the solution and explanation. I'd love your feedback or questions.
I created a symmetrical logic‑gate diagram and challenge you to spot its function. Study the image, try simplifying the design, and use the provided hints if needed. If you enjoy puzzles or digital logic, read the full post for extra challenges and to compare solutions.
