Rule Referee
Instant board game rules — no more mid-game arguments
What it does
Rule Referee started at a family game night where we spent more time arguing about Mexican Train rules than actually playing. I built a search engine that pulls answers directly from real rulebooks, not AI-generated guesses. It's deterministic, not generative. It's designed to say it doesn't know rather than make something up. Currently 15 games including Catan, Exploding Kittens, Chess, Mexican Train, and more. Chess and 3 games of your choice or $2.99/month for all access. iOS only for now.

- PAPlay abstract strategy board games online with friends or against botsOct 2025 · abstractboardgames.com · ▲180
Thought I would post in celebration of 1 year of my website being online. I've been working on it on and off and currently the website allows users to play Hex, Tumbleweed, Amazons, and Connect 6 against friends or against practice bots. I've been a long time player of some of these games and I felt for a long time that the world could use a few more popular abstract strategy games compared to Chess or Go. If you try it, let me know what you think. I'm always looking for new games or new features to add :)

Hey we are Computable. We spent years building trading infrastructure at Jump Trading and Coinbase. From that point of view, compute looks like energy markets before 2000: everything trades through private bilateral leases, there’s no visible price, and nothing can be resold. The same H100 rents at a 2x spread depending on who’s asking, and once you sign a 24-month lease, it can never change hands. So we built a market for GPU nodes, sold by the calendar week. Here are three things you can do on it that you can’t do anywhere else: - Buy exactly the weeks you need. Three nodes for the last…

Hey HN, Henry here from Cactus. We open-sourced Needle, a 26M parameter function-calling (tool use) model. It runs at 6000 tok/s prefill and 1200 tok/s decode on consumer devices. We were always frustrated by the little effort made towards building agentic models that run on budget phones, so we conducted investigations that led to an observation: agentic experiences are built upon tool calling, and massive models are overkill for it. Tool calling is fundamentally retrieval-and-assembly (match query to tool name, extract argument values, emit JSON), not reasoning. Cross-attention…
