Pixelogic Weekly #7
Nonogram puzzles for the week of May 18, 2025
Hello logic puzzle lovers. Hope everyone had a good week.
The playtest for Pixelogic on Steam kicked off this week, and I’m already getting some great feedback. There is still some time to join, if you want. Visit the Steam page and click “Request Access” to join the waitlist.
How many 5x5 nonogram puzzles are there?
Classic nonogram puzzles are binary—each square is either filled or empty. Therefor, the total number of possible combinations of pixels can be determined by the formula:
\(total = 2^{width * height}\)So, for a 5x5 puzzle, the total number of possible pixel combinations are:
\(2^{5*5} = 2^{25} = 33,554,432\)That means for a 5×5 puzzle, there are over 33 million possible ways the pixels could be arranged. That’s a quite a lot! Of course, not all of those are valid puzzles. A valid nonogram has to be solvable and have a unique solution—no guessing required.
I ran my nonogram solver on all 33,554,432 possible 5x5 puzzles. Can you guess how many of those turned out to be solvable, logic-only puzzles?
Take a guess—and I’ll reveal the answer next week!
