    Hi HN, I was inspired by Wordle to make Colorfle, a different take on the genre where the goal is to mix colors together to match the target color within six tries. There were some interesting problems to tackle in making this game, one of them being the difference between mixing digital colors and real-life behavior (in RGB, blue + yellow = grey!). I hope you enjoy it -- any feedback would be much appreciated!

    I’ve been working on a puzzle game for a few years as a side project. The game is based on a small region of tiles in a grid that is mirrored, modified, and mirrored again. It’s based on a novel phenomenon I noticed where, once these mutations happen a few times, the original region can be hard to recognize. You have a feeling there are symmetries in the image, but they are just out of grasp. Going further, if only part of the region is visible, such as mirroring off the edge of the board, it adds to the feeling and it becomes a satisfying puzzle to solve. I originally published this on the…

    "Lights Out" is a mathematical puzzle that lives on an grid where each cell of the grid is one of two colors: either red or white. The goal is to eventually get all the cells in the grid to be red. What's the catch? Clicking a cell will not only flip its color, but also that of all cells sharing the same row or column as it. To me, this game feels like playing with a Rubik's cube --- every time you think you are fixing one cell, you mess up its neighbors! There are many ways to arrive at a solution... some mathematical (linear algebra, or combinatorics), others more logical,... and yet…
