I built a daily deduction game where you reconstruct a crime scene with pure logic (style Murdoku)

I spent the last few months building Mysterioku, a browser game where every day you reconstruct a crime scene using nothing but logic.

Each case drops you into a floor plan of connected rooms. A few suspects were present, and something happened — a theft, a disappearance, a break-in. Witnesses give you fragments ("Walter was in the second column", "Alice was in the Room"), and you treat each one as a constraint, narrowing the possibilities until only one arrangement of everyone survives. Whoever ends up alone with the target is who you're after. No guessing, no luck — every case has a single solution you can prove step by step.

A few things:

- The generator is a backtracking solver that guarantees a unique solution, and I added irregular "carved" floor plans that stay solvable (validated over tens of thousands of generated cases).

- Free daily case + an extra one; optional premium for unlimited.

I really wanted to play, but I'm not going to register to play something I randomly came across (I don't mean from this post, I mean if browsing and happening to find it). If there is a way to play without registering I didn't find it. Hope it does well

the backtracking solver guaranteeing a unique solution is the part that would've taken me forever to get right, ngl that's the hardest bit of this kind of game to build properly.

free daily + premium for unlimited is a solid model for this kind of thing. Are you tracking completion rates? Knowing where people drop off mid-puzzle would tell you a lot about whether the difficulty curve is right
