Hello, HN - I wanted to share this puzzle game I made during my vacation. I'm rather fond of the pipes puzzle where your goal is to restore a scrambled network of connections by rotating tiles. It's usually played on a grid of squares and this all started when I decided to make a programmatic solver for that kind of puzzle. Then I realized that with some minor changes the solver could generate new puzzle instances. I thought about what kind of puzzle to make and someone suggested a hexagonal grid. Adapting the generator wasn't too hard but then I had to create a way to play this variant. So…

Hey HN! I just finished building a puzzle game called Corral, and I’d love to share it with you. It’s a logic puzzle played on a rectangular grid, where some of the cells contain numbers. Your goal is to mark which cells are inside a single continuous loop that encloses all the numbers. For each numbered cell, the number tells you how many cells are visible in the four orthogonal directions (up, down, left, right) until a wall of the loop is hit, plus the cell itself. So a cell with a 2 must see one empty cell before hitting the loop boundary. Gameplay is all about deduction: you can mark…
