The team used a hybrid architecture: an Android GridLayout with 225 tile Views integrated into surrounding Jetpack Compose UI. ### Source excerpt How We Made a 15X15 Game Surface Feel at Home on AndriodIllustration by Lehel Kovács By Shafik Quoraishee What Is Crossplay? The New York Times Games team has been building daily puzzles for quite a while: Wordle, Spelling Bee, Connections, The Mini. These are solo games. The player opens them, solves them, and then closes them. This leads to a simple, satisfying experience which delights millions of players a day. Crossplay is an altogether different endeavor. It's the first multiplayer game from NYT Games, and it brings a friend (or a stranger) into the experience with them. So two players, one board, in real time. In Crossplay, players take turns placing letter tiles on a 15x15 grid to form interlocking words, but built for mobile with a focus on speed, fairness, and the back-and-forth tension that compels the player to play one more round. The matches are asynchronous by default. The player makes their move, the opponent gets notified and responds when they're ready. But the board animates as if the players are both sitting at the same table. When we set out to build it, we knew the board would be the hardest part. While the networking, the opponent matching, and the game logic were all challenging work, the board itself which is part of the core game loop was the most difficult piece because of the number of interactions required to make it function correctly, in concert. Since every cell is a potential drop target and every tile is draggable, the board needs to respond instantly to touch *and* animate their opponent's moves *as they happen*. This all must occur on a screen that is a few inches wide. In this post we discuss what it took to get that right on Android. Starting with the Grid One of our first questions was architectural. How should 225 tiles be laid out? Jetpack Compose is the obvious modern choice. But Crossplay's development started before our team had fully migrated to Compose, and the game board had specific requirements that made a pure-Compos ## snakes.run: rendering 100M pixels a second over ssh DevFeed: [snakes.run: rendering 100M pixels a second over ssh]() Original publisher: [Read original article]() Author: Nolen Royalty (eieiogames@gmail.com) Published: 2026-02-25T00:00:00Z Content type: article Language: en Sources: [eieio.games]() Topics: [ssh](), [Go Language](), [Back end](), [Text-based user interface](), [ASCII]() Tags: [backend](), [go](), [multiplayer](), [performance](), [pixels](), [render](), [server](), [ssh](), [terminal](), [text](), [unicode]() ### AI overview An engineering article explains how snakes.run delivers a massively multiplayer snake game over SSH.

It discusses challenges including peak matchmaking delays, unfair pairings, idle capacity, risky rollouts, and limited operational visibility, then outlines a design using Open Match, Agones, Kubernetes, and a health and latency service. ### Source excerpt By Vaibhav Naik Every great game starts with great tech -- and great people behind it. If you're passionate about crafting seamless, high-performance gaming experiences that bring players closer to the sport they love, we'd love to have you on our team. Explore our open roles at Dream Cricket. Why Multiplayer Matters on Dream Cricket We've always believed that the best games are the ones that bring people together. And that's exactly what multiplayer on Dream Cricket does -- it turns gaming from a solo challenge into a shared moment. The banter, the thrill of a close finish, the satisfaction of a fair match -- that's what keeps players coming back. Over the years, as our player base grew and expectations rose, we knew our multiplayer system needed to be scaled. It had to be faster. Fairer. The kind of system that doesn't break under pressure, whether it's lakhs of players logging in during a live event or two friends battling it out over spotty mobile data. This blog is our story of getting there. It's about how we rethought everything, from how we match players to how we run thousands of servers all at once. You'll get a look at the roadblocks we hit, the calls we had to make, and how open-source tech like Open Match and Agones helped us build something truly scalable. Building for the Next Era of MultiplayerThe Challenge Our initial multiplayer setup used a simple queue and a fixed pool of servers, which worked well. As adoption grew and large-scale events became frequent, the system was unable to manage the load. We had to move from basic matchmaking to skill-based fairness, surge handling, safe releases, and cloud portability. And as we scaled, familiar pain points surfaced: High P95 time-to-match at peak; cancellations rose Unfair pairings in upper tiers; noticeable re-matches Idle server waste off-peak; slow warm-up during spikes Risky rollouts without clean canaries; limited on-call visibility The challenge was clear: we needed to decouple matchmaking logic from ## Closing SSE Connections: A Browser Compatibility Deep Dive DevFeed: [Closing SSE Connections: A Browser Compatibility Deep Dive]() Original publisher: [Read original article]() Author: James Heller Published: 2025-11-20T19:00:00Z Content type: tutorial Language: en Sources: [Apartment 304]() Topics: [Server-sent events (SSE)](), [JavaScript](), [htmx](), [HTTP](), [Firefox](), [Chrome]() Tags: [ajax](), [apartment-304](), [browser](), [compatibility](), [custom-software-solutions](), [devops](), [devops-engineer](), [htmx](), [http](), [implementation](), [issue](), [javascript](), [multiplayer](), [software-architecture](), [software-development](), [software-engineer](), [sse]() ### AI overview This tutorial explains how Server-Sent Events connections can remain open inconsistently across browsers when users navigate away.

It discusses the project's international multiplayer community, financing through donations and donated resources, low-cost hosting, and the use of virtual private servers. ### Source excerpt It's been roughly 3 years since DDraceNetwork (DDNet) started in the summer of 2013. Last year I wrote a non-technical History of DDNet. Today in this post we will dive into the technical side of what makes DDNet run. For the uninitiated, DDNet is an open-source modification of Teeworlds, a retro multiplayer shooter. DDNet is a game in which you, instead of killing each other, cooperate with each other to work your way through challenging maps, trying to beat the map or get a better time than other teams. What we offer for DDNet is the client and server software as well as official servers that run all around the world. We have an international community of players trying to beat the latest maps and records, and dozens of mappers who send in their newest creations for our consideration. A new map is released every few days and occasionally tournaments happen in which the best compete against each other on brand-new maps. At the time of writing there are 968 people playing Teeworlds, 678 of which are on a server running the DDNet mod, and 430 on the official DDNet servers. So this project is not especially big and not many people stumble upon DDNet. Our player base consists in a large part of old Teeworlds players and their friends who heard about us by word of mouth. Nevertheless I hope that the technical challenges we faced and face as well as our solutions are interesting. Let's start with an overview of what we have: Overview & Financing DDNet runs official servers in Germany, Russia, USA, Canada, Chile, Brazil, China, South Africa and Iran. Since DDNet is totally free, has no advertisements and no in-game purchases, it offers no stream of revenue and is solely funded by donations, donated servers and my own money. So one of the goals is to keep costs down: On average we pay 10 EUR per month for each location. Let's see what we can offer with this to our thousands of players (detailed statistics) and how DDNet evolved to keep with increasing number of players, maps
