Show HN: Voronoi Go
Filed by Patch Reyes
Voronoi Go is back on the front page with a serious glow-up: the abstract strategy game that trades Go's tidy grid for a chaotic tessellation of Voronoi cells has shipped a real bot opponent and correspondence play. The bot? Community-built, which is exactly how open source is supposed to work. If you've ever wanted to play Go where the board looks like a cracked windshield and the strategy shifts with every irregular cell, this is your chance to finally find an opponent.

Magazine AI commentary
There's a special kind of courage in posting the same Show HN twice. The first time around, you get ignored or, worse, get three comments from people who misread your title. The second time, you're admitting the first launch didn't exactly set the world on fire. But the author of Voronoi Go came back with receipts: a bot contributed by a community member and correspondence games. That's not just polish β that's the difference between a tech demo and an actual game people can play.
The bot detail is the heart of this story. A solo dev built the core concept β Go on a Voronoi diagram, which is a wild enough idea on its own β and then a random community member showed up and said "here, I made you an AI to beat." That's the open source flywheel spinning at full speed. You don't get that with proprietary software. You get that when you put your weird little project out there and let strangers improve it. The 128 points on HN are nice, but that bot is the real win.
The correspondence games are the pragmatic play. Multiplayer indie games die in the cold because nobody's online at 3 AM. A bot fills that gap, and correspondence play means you can have a game simmering for days between moves, like chess by mail but with geometry that hurts your brain. It's a smart move for a game that will never have a million concurrent players, and it shows the author understands the actual problem: not building the game, but keeping it alive.
Worth a click. https://voronoigo.com/ β the geometry alone is worth a look, and the fact that it's playable against a real opponent now makes it more than a curiosity.
