Daniel,

Curious about the mathematical principles behind this game. How do you guarantee that each layout has a unique solution? Saw the screenshots but did not quite grasp the game's mechanics.

Hi, thanks for asking!

Maybe the video can clear it up a bit. The game itself introduces the mechanics in a way that is simple to understand.

Basically, you start filling up the board from the cells marked with an X. From an X, you can link up to any number, e.g. X -> 2. From a number, you can link up to any other number that is NOT inferior, e.g. X -> 2 -> 2 -> 3 -> 5 (but not X -> 2 -> 1). You do this until the whole board is linked up. Eventually the rules become second nature.

As for guaranteeing unique solutions, I made my own automatic solver which is basically an heavily optimized recursive backtracker. So I can just make/edit a puzzle by hand and immediately check how many solutions it has. All puzzles have exactly one solution, except for two specific puzzles which were intentionally designed to have multiple solutions (puzzles 145 and 383).

Apart from the solver, making puzzles is a manual process, something I set my mind on from the beginning because personally I prefer handmade puzzle games to autogenerated ones. Making a puzzle can take anything from 10 minutes to 1 hour, depending on the size, number of holes, etc. They were also tested multiple times (in different days) to verify that the difficulty conforms to my intentions and that the tricky spots remain tricky long after I forget how I made the puzzle.

Happy chaining!

150 levels in!
As a logic puzzle fan, what drew me to this was the promise of unique solutions to every level - I consider this really important for logic puzzles and not enough games out there do this. It’s really awesome that this is something you’ve included in the design philosophy for this game!

It’s definitely addicting and the difficulty is starting to ramp up - can’t wait to see what the later parts of the game are like!

Huge amount of carefully made content. I like it!

Thanks a lot for the kind words!! Keep playing and you might find a little surprise
