This is the first iteration of a short game I’m making that tries to interactively explain some of my favorite math questions / ideas. My goal is mostly to get the player curious and not necessarily to explain absolutely everything. There were a lot of fun technical parts to building this: - For implementation reasons, it’s much easier if the lines all have integer intersection points with each other. To do this, when a new line is added I “cheat” by rounding intersections to integers and then splitting the old lines at the intersection into new linds (with potentially different slopes)…

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 there! I'm the brains behind the math crossword game on my site. This game is all about making math a little more fun – users just drag and drop numbers to fill in the blanks and move on to the next level if they get it right. Let me know if face any issues or have any suggestions! :)

I’ve been building a few small games to help kids (and curious adults) build reasoning and logic skills. Think Word Ladder, Prime Hunter, Math Maze ,all in the browser, no installs. Would love feedback or suggestions for new types of puzzles

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…

This is a tetris style game where you need to fill 5×8 grid completely with 10 falling blocks. Simple game based on skill and logic. Feedback is much appreciated.
