Show HN: Clues by Sam – a daily logic puzzle using natural language in a grid
cluesbysam.com
It resembles Murdle in the sense that the puzzle is set using natural language instead of game specific rules. This way anyone can start playing right away without first internalizing a set of rules. But unlike Murdle, this game works on a grid, leveraging known solving techniques from puzzles like nonogram, starbattle and fill-a-pix. The game also has a kind of fog-of-war keeping the solve tree tight and approachable. To prevent mistakes from spoiling the solve path, behind the scenes there's a constraint solver that prevents you from doing "guesses". The only way to lift the fog-of-war, to reveal new clues, is to find the next 100% logical choice. Just like in real life, you can't convict someone on a 50/50 hunch!
The majority of the work for creating this game was making the level generator. Levels are generated and curated (not all levels end up fun, and there are still some quirks). The generator ensures the puzzle has a narrow solve tree, poses challenging deductions, and is always solvable using some "technique" instead of through a long chain of backtracking.
There's still some ambiguity that comes from using terse natural language. To counter this there are some clarifying details listed under the game. The two main sources of confusion are: 1) Neighbors include diagonal neighbors. 2) To the left/right/below/above means in the same row/column.
If you have challenges with the red/green colors, there's a button for toggling the theme.
Side note: The name "by Sam" is just something I started using for my games recently. Just a short gender neutral name I happened to like. My name isn't actually Sam.
