Hey PH! 👋 I'm Shawn, the maker of Griductive.
I've always loved logic puzzles — the kind where you deduce the answer step by step, with no guessing involved. But I couldn't find a daily puzzle that scratched that itch. Wordle is great, but it's pure word guessing. I wanted something that demanded real deductive reasoning.
So I built Griductive: a daily logic grid puzzle where you classify a set of suspects as guilty or innocent using only the clues given. Every inference must follow logically. No luck, no shortcuts.
A few things I'm proud of:
- Multiple grid sizes (3×3 → 5×5) so beginners and veterans both have a challenge
- A Reddit version (r/Griductive) that's brought in a surprisingly engaged community
- 6+ minute average session time from day one — people are genuinely thinking!
Would love your feedback — especially on difficulty balance and which grid size you gravitate toward. Happy to answer any questions!
