Maybe the most famous puzzle I made is the “Clock Calculator Bulb” Puzzle.
The puzzle was published for the first time on 14 April 2020, in the middle of the COVID-19 crisis. This helped the logic puzzle go viral, and it was shared millions of times on social media worldwide. This puzzle’s power is its simplicity, it is just black with a white background and has three transparent objects. Like many of the “123 Puzzle Me” puzzles, it looks straightforward to solve, but not all is what it seems. Do you know the answer?
Like most of the puzzles I made, it’s in the details and not as easy as you might think.
Give it a go, and if you think you know the answer, check the explainer below to see if you’re right.
One of the first math puzzle explainers I made was the Basic Black / Clock Calculator Bulb logic puzzle explainer. No voice-over from Jarvis yet; we didn’t meet at that moment. But a cool tune and in a simple way explained how you should solve this math puzzle.
