Fillomino by Thomas Snyder
[This is a repost from our archives with new notes at the top (original post here): The final puzzle of our first sixty set, this Fillomino takes advantage of several less common look-ahead steps to make progress towards the solution. While I hadn’t constructed as many Fillomino before in my life, I learned a lot from this week of experimentation ten years ago and still find Fillomino to be a really rich style with a lot of distinct author styles to be found within it.]
