Welcome to London 2-player Playtests, a friendly meetup open to everyone interested in playing 2-player or solo games. You don't need to bring a game - we always love to have new playtesters! For designers: Whether your game is for TWO PLAYERS, a SOLO experience, or a larger game you’d like to test with fewer players, this event is for you! Please comment with the game length, whether you need 1 or 2 playtesters, and a brief description. The event is free and will take place at the National Theatre: https://maps.app.goo.gl/74QGHXWPs5KZH6MC9 We'll meet around 6:15 pm, and playtesting sessions will begin at 6:30 pm. If you'll be joining at a later time, please let us know in the comments! If you're a designer arriving late, please be aware that your game may not get playtested. Join us for an evening of engaging playtests and creative feedback!

Playtesting comes to Bay Games, Whitley Bay's game cafe. A full afternoon of demoing, with Playtest UK volunteers on hand to connect gamers with games. Bay Games has been supporting game designers since first opening its doors, and we're thrilled be joining them for this event. This page is intended for designers to register interest. If you are interested in demoing - and you have not already messaged me - please comment here BEFORE Monday 29th June. You can bring as many different prototypes as you want but the event is not intended for promotion - any posters, flyers etc must be no larger than A4 size. Any questions feel free to comment!

We playtest all sorts of tabletop games - strategic, silly, creative, or whatever (but not video games). Some games are almost done. Some are very early ideas. We test anything that will fit into 90 minutes. You don't need to bring a game - we always love to have new playtesters! Please let us know in the comments when you plan to arrive/leave and whether you are bringing a game or not. This helps us to plan the day better. The schedule is: 10am onwards - gathering, chatting 11am sharp - playing for 90 min ('slot 1') 12:30ish - break for food/chat 1pm sharp - playing for 90 min ('slot 2') 2:30ish - break for food/chat 3pm sharp - playing for 90 min ('slot 3') 4:30ish - finish up Often, we might hang around afterwards, to play some already-published games. We are strict on timings, so please try to arrive a few minutes before the session to limit disruption. You can just come for part of the day if you wish. The reason we have fixed timings for the 3 'slots' is to make it easier for folk to do so. Designers of all levels of experience are welcome! But if it's your first time, we ask that you don't bring a game and just spend some time learning how the group works. The group works based on reciprocation. If you expect to test your own game, make sure stay for long enough to play other games. As a general rule of thumb, you can expect to play one of your own games every third 90-minute session. So if you stay a whole day (3 sessions), you can expect to have one session to play your game(s). A good rule of thumb is that if you come all day, you will have one 90 minute session with two other playtesters in which to test your own games. It is sometimes possible to test games with more players. If your game requires 4 or more, please note that as standard you will be allocated half of a session (45 minutes). Pre-covid, we were getting unmanageable. As a result, we may have to limit attendees. This is a free-to-use venue, and we have to be mindful that other folk want to use the same space. Please note: This is an adults only event. We look forward to seeing you!

AI assistants are getting more capable. The question is how we build effective workflows around them. At DevDay London, [Lucy Joyce](https://www.linkedin.com/in/lucy-joyce-597485166/), [Ash Shakrani](https://www.linkedin.com/in/ash-shakrani/) and [Arun Kurian](https://www.linkedin.com/in/arun-mathew-kurian-39b8aa5a/) will explore harness engineering through the lens of a payment integration. From requirements and design through to implementation, they’ll demonstrate why context alone isn’t enough for successful AI-assisted development. Drawing on real-world experience, they’ll show how engineering harnesses, reusable context, standards, and validation workflows help teams move beyond experimentation and build reliable, scalable AI-assisted development practices. **This session will unpack:** 🎯 Why “more context” isn’t the answer on its own 🎯 What engineering harnesses are and how they create reliable feedback loops 🎯 How standards, workflows, and validation reduce AI-generated rework and technical debt 🎯 Practical techniques teams can adopt immediately to improve AI outcomes 🗓️ **Save the Date:** 2nd July, 2026 📍 **Location:** Sahaj Software, 1 Quality Court, London, WC2A 1HR 🕕 **Time:** 6:00 PM – 8:00 PM (BST) The evening will feature: 🎤 **One engaging talk** with Q&A 🤝 **Plenty of time for networking** over free pizza and non-alcoholic drinks Don’t miss this chance to learn, connect, and share with fellow tech enthusiasts. 👉 Please click the link below to register. https://sahaj.ai/events/harness-engineering-in-practice-from-requirements-to-implementation/

Taking inspiration from the exhibition at the V&A Photography Centre we will embark on a street and environmental photography workshop. Photographers currently on display are Elliott Erwitt, Robert Mapplethorpe, Dorothea Lange, Edward Weston and the controversial Sally Mann amongst other giants. Come and learn a little history of the photographers and be surprised at who shot some well known music album covers! Afterwards we will head out and shoot street and environmental photography around South Kensington. EQUIPMENT * Any camera * Any lens * An open mind and fun attitude!

Registration Must Happen on: [https://www.eventbrite.com/e/building-an-ai-powered-b2b-outreach-engine-find-qualify-convert-tickets-1992273247915?aff=oddtdtcreator](https://www.eventbrite.com/e/building-an-ai-powered-b2b-outreach-engine-find-qualify-convert-tickets-1992273247915?aff=oddtdtcreator) From finding the right leads to the final follow-up - personalisation at scale. Generic outreach is dead. Spray-and-pray emails get ignored, burn your sender reputation, and waste hours you don't have. In 90 minutes, you'll build something better: an AI-powered outreach engine that finds the right businesses, qualifies them automatically, and writes personalised messages at scale that actually get opened and answered. Not just theory. Not "use ChatGPT to write faster." A real, repeatable system — built live, around an actual EU brand. You'll watch the full cycle work end to end, then walk out ready to run it on your own business tomorrow. Here's what you'll walk away with: 🎯 Find — Pinpoint your ideal customers and pull a clean, structured lead list from sources hiding in plain sight. AI does the heavy lifting. ⚡ Qualify — Turn your gut instinct into a scoring system the AI runs at scale, so you only chase leads worth chasing. ✉️ Convert — Write outreach that goes way beyond {{name}} — then sequence follow-ups that hold the thread and pull replies. By the end, you won't just understand AI outreach. You'll have designed the engine. Perfect for SME owners, founders, consultants, employees and students who want a system that works — not another AI demo. Seats are limited and these fill fast — grab yours now. 🕐 17:15–18:45 workshop · 18:45–19:15 networking & refreshments 📍 Barclays, 120 Moorgate, London 🤝 In collaboration with Barclays

NFT's are here to stay folks! This is a group for like minded people interested in understanding, leveraging, using, creating for, profiting from, trading too i suppose, NFT's.. everything around them, complexity, fear and exploits, best practices and more. **PLUS** This group will talk AI ART tools, techniques, artists, video, audio, prototypes and more in the AI assisted production space- ART specifically, but we can get into any aspect of some of the cooler things happening in AI in general.

You can sleep in on the Sesquicentennial (observed), we’re shifting to the following Friday. But join the local UX community for a chat and some biscuits to catch up. If you were in CA for Figma Config, tell us all the lines and you can tell me how I can animate an SVG without coding it by hand, and why I’d even want to. Thanks to the team at Nationwide of supporting the group.

Whether you've never done improv before, or you've done it for so long you were quoted in *Truth in Comedy*, or anywhere in between, come join us! Swing by *Gresso's* for the **Columbus Improv Comedy Meetup**! The idea behind improvised comedy is to create entire scenes from scratch. A suggestion is taken from the audience and laughter is built on the spot. This can be done in game form, like *Whose Line Is It Anyway, Make Some Noise,* or *Wild 'n Out*; it can also be done in a longer way, to tell a complicated story, like *TJ & Dave*. Our meetup, which is central Ohio's longest running (and FREE!) weekly comedy event, brings the games for you to play in a safe, supportive, and compassionate environment. Afterward, many members will hang out in *Gresso's* itself and get to know each other. Not only is this a lot of fun, but you get to work on thinking faster on your feet, your public speaking, plus it's an excellent way to meet new people and build relationships that will last a lifetime, and you do that while laughing your butt off! Ask yourself if you want to join the **Columbus Improv Comedy Meetup**, and say "*Yes, And*" that you'll have a blast!

Most people use LLMs by feel: ask a question, read the answer, decide whether it “seems good,” and move on. That works for casual use. It does not work when you are building software, automating workflows, writing important documents, or relying on AI for anything that needs to be repeatable. In this talk, we’ll look at how to improve and evaluate the inputs and outputs of LLMs using practical measurement techniques. We’ll cover how prompt changes affect results, how to compare outputs, how to build simple evaluation sets, and how math-based methods like similarity scoring can help you move beyond guesswork. This will be beginner-friendly, so even if you don't know anything about AI, you should get something out of it. However, this will be a little more technical than our intro talks. You do not need to be an AI researcher, but programmers and technically curious attendees will get a lot out of it. We’ll cover: * Why “it looks good” is not enough * How to improve prompts by changing the input, context, and constraints * How to compare LLM outputs more systematically * Basic evaluation techniques for accuracy, consistency, and usefulness * How embeddings, cosine similarity, and scoring can help evaluate results * Where automated evaluation works — and where humans still need to stay in the loop By the end, you’ll have a practical mental model for treating LLMs less like magic and more like systems you can test, measure, and improve. LOGISTICS AND PARKING: The talk starts at 7:00 PM. The first half hour is reserved for everyone to get set up and mingle. Free pizza and drinks! The cheapest parking option is to find street parking, which will only cost you a few bucks. Otherwise, park in the nearby veteran's museum lot for $8. It's highly recommended you avoid the nearby $15 garage parking.

Come attend a free in-person seminar where you will find out why you: -Feel isolated -Can't express yourself openly -Get nervous or anxious in front of people -Run out of things to say or feel tongue-tied -Feel introverted -Don't feel comfortable in any social setting -Can't make more friends -Are shy and miss opportunities to connect in a meaningful way And we cover what you can do about any one, some or all of the above. This seminar is the weapon against loneliness, isolation and boredom, come join us! COME TO THIS SEMINAR AND LEARN THE SECRETS TODAY This seminar is brought to you by the Dianetics & Scientology Life Improvement Center. 1266 Dublin Road, Columbus, Ohio 43215

Bring your Raspberry Pi, Arduino, microcontroller, or any other electronic project and join fellow electronics makers for a night of creativity and collaboration! This session is open forum to share your current projects—whether complete or in progress, it’s all interesting! Whether you’re deep into embedded systems, exploring new ideas, or just getting started, you’ll find a welcoming space to collaborate, share, and get inspired. **New to electronics or curious about tinkering?** You’re absolutely welcome. If you’re a beginner and want to experiment, I’ll have a couple of starter kits available so you can try things out—whether that’s blinking your first LED, putting something on a display, or experimenting with simple sensors. No pressure and no experience required—just an interest in learning and building. While we continue to pursue a more permanent venue for this Meetup, we’ll be using public library facilities based on availability.
