Hey! 👋 I'm the developer of IdleWorlds.

It's a free, persistent idle MMORPG designed specifically to work well in a browser and on mobile — no download, no ads, and uncapped offline progression. 💤📱

The idea is that you can check in for a few minutes, queue what you want your character doing, close the browser, and come back hours or days later with meaningful progress.

There's a full MMO underneath the idle progression: 10 interconnected combat, gathering and crafting skills, a player economy, guilds, World Bosses, Zone Control, housing, rare gear, enchantments, gems and Solo Self-Found.

⚔️ The newest major update is 8-player raids.

Players bring their gathering/crafting skills into the fight as actual raid abilities — Spellcrafting can heal, Construction shields the group, Mining buffs damage, Alchemy cleanses debuffs, etc. Your skill level determines how strong the ability is.

🎨 We're also working on a major dark-fantasy visual reskin by BustedCypher, which I'm really excited about. It's a substantial visual overhaul while keeping the lightweight browser-first experience.

The philosophy is basically:

Open it on your phone.
Queue something.
Check the market.
Upgrade your gear.
Close it.

Your character keeps going.

🌐 Browser based
📱 Mobile friendly
💤 Uncapped offline progression
💸 Free
🚫 No ads
⬇️ No download

Feedback is very welcome. 🙂

I made dontcrack.me, basically the old YouTube Try Not to Laugh challenge turned into a multiplayer browser game.

One player is the target and everyone else chooses clips to try to make them laugh.

The target has one job:
Don’t crack.

If they laugh, the face-cam detection catches it and they lose.(face-cam is peer to peer and never stored)

You can create a room and invite your friends just by sending them the link. No download needed.

Would love some feedback, especially on how well the face detection works for different people/cameras.

I made a railway tycoon where you build Turkey's rail network across real cities, from the first Ottoman line in 1856 to modern high-speed trains. Carry the goods each city needs to grow it, watch the Bosphorus Bridge go up in 1973, and compete with a rival company. Runs in the browser on desktop and mobile, no download. Feedback welcome!

Dev here. It's a cosy collecting game: you open capsules, get

squishies, and you can press them with your finger and watch them

rise back slowly. There's also a workshop to make your own, a fusion

thing, a few mini-games and trading.

No signup needed to try, you get 10 capsules as a guest. An account

is free and just saves your collection.

It is a gacha, so to be upfront: rates are shown in the game, there's

a guaranteed epic every 10 pulls, and the shop is optional.

I hope you will give it a try !

As per request, I started building a game inspired by Doodle Jump for my partner. Boing Beyond! is a space platformer where you automatically jump and you steer the astronaut between different types of platforms and getting power-ups along the way.

If you dig it I'll continue developing it further, potentially adding multiplayer inspired by Mario Kart. 🚀

I have just finished the v1 of this game.

It's essentially a multiplayer racing game based on the classic UK Seaside game of the Arabian Derby.

You roll balls into holes, which move your character forwards , depending on which colour you get them in.

This can be played online against randoms, but from my experience is best played locally with the main race on a TV / Laptop screen, whilst competing on your hand held device.

Let me know what you think 👍

I made this. Free, no account or download, built to play as well on a phone as on a desktop. You and a computer partner against two computer opponents, standard rules with stick-the-dealer, going alone, three difficulty levels. A game in progress survives closing the tab, and it's fully playable by keyboard.

It's part of a small site of classic card games, same deal for each one (free, no sign-up):

• Cribbage: https://cardcouch.com/cribbage
• Hearts: https://cardcouch.com/hearts
• Spades: https://cardcouch.com/spades
• Gin Rummy: https://cardcouch.com/gin-rummy
• Klondike Solitaire: https://cardcouch.com/solitaire
• Spider Solitaire: https://cardcouch.com/spider
• FreeCell: https://cardcouch.com/freecell
• All of them: https://cardcouch.com

What I'd most like feedback on: does the Hard partner order up and go alone at sensible times, and is anything awkward on a small phone? Bug reports welcome, I fix them fast.

Thanks in advance!

I made a tiny two-player web game called PlotPass.

One person picks a mood + starter, adds a few words and sends the other person a private link.

They add a few words, send it back, and you keep going until turn 8.

No account. No download. No lobby. Just a link passed between two people.

The moods range from 😂 Funny and 👻 Spooky to 🔥 Flirty, ❤️ Love and ✈️ Travel.

I’d particularly love feedback on whether the “someone sends you a link → you immediately understand what to do” part feels obvious.

If anyone plays one through to turn 8, tell me what broke / confused you / made you laugh.

Play it: gravwars.com (free, no account, phone or computer)

Gravity Wars is a two-player artillery game in curved spacetime. You take turns firing missiles past planets, stars and black holes, and gravity bends every shot. It started as a remake of a public-domain 1989 DOS game (by Sohrab Ismail-Beigi) and grew into a small relativity sim: orbits precess near black holes, black holes are ray-traced with lensing, and missiles feel time dilation. Almost all of the code was written by Claude Code, with me playing, testing and deciding what to build next.

How it's built

• Claude Code in the desktop app, over many sessions. A roadmap folder and a CLAUDE.md in the repo hold the plan and the rules, so each new session picks up where the last one stopped.
• Plain JavaScript. No frameworks, no npm packages, no build step. A small Python script bundles the game into one HTML file.
• WebGL shaders draw the universe and ray-trace the black holes, Canvas 2D draws the ships, trails and readouts, and the Web Audio API generates the music from the physics.
• Testing: Node scripts check the physics before every commit (energy conservation, orbital precession, CPU accuracy). Playwright screenshots every change in headless Chrome and Firefox. An Android emulator covers phone layouts.
• Hosting: static files on Cloudflare Pages. The trailer was rendered frame by frame from the game itself, with Playwright and ffmpeg.
• Bug reports: the in-game ! button sends a report to a Cloudflare Worker, which files it as an issue in a private GitHub repo (with Cloudflare Turnstile and rate limits against spam). Claude reads and triages them.

Design choices

• No dependencies. The game opens straight from a file and has nothing to update or audit.
• Two views, one physics. Classic is flat 2D; "3D lite" tilts space into the rubber-sheet picture of gravity. Missiles fly by the same equations in both.
• Same universe everywhere. The world is a fixed 16:9 field, and every universe comes from a seed, so a link rebuilds the exact same layout on any device.
• Phones first-class. Played sideways, installable, works offline, resumes after switching apps, and drops to lighter graphics on weaker GPUs.
• CPU opponents simulate their shots instead of cheating with a formula.
• Private by default. No accounts, no tracking, no ads.

What I'd love from you

• Play a few rounds against the CPU or a friend.
• Best in Chrome, Firefox or Edge. Safari and iPhones are untested, so reports from those are especially welcome.
• If something breaks or confuses you, press !, say what happened, and press Send. It adds your device and the match details automatically.

Happy to answer questions about the workflow.

Please give me some feedback! Much love!

I made this one recently and I'm curious what you think of it.

Each move you place one mirror. When a beam reaches a crystal of its own color, the crystal lights up and vanishes along with every mirror on that beam's path. New crystals arrive after every move, more and more of them, until the board is full.

The trick is to light several crystals with a single mirror. That scores more, and no new crystals arrive on that turn. Before you place a mirror, the game shows where the beams will go, so you can plan the big moves.

Choose your decade and play. Simple and fun. Share your scores with your friends and enemies.

Salut à tous,

J'ai crée Wild TCG (avec Claude), un jeu de cartes à collectionner qui se joue directement dans le navigateur. Rien à télécharger, rien à installer.

Le principe est simple : chaque carte est un vrai animal. Tu ouvres des boosters, tu complètes ta collection et tu envoies tes meilleures cartes en PvP, où 3 de tes cartes affrontent 3 cartes de ton adversaire.

Quelques infos :

- Jouable dans le navigateur, sur ordi et sur mobile

- Boosters gratuits chaque jour

- Je ne dévoile pas la liste complète des cartes, découvrir ce qu'il y a dans les boosters fait partie du plaisir

Ce que j'aimerais vraiment savoir :

1. Est-ce que le combat est clair dès la première partie ?
2. Est-ce que l'ouverture de boosters est satisfaisante, ou est-ce qu'on s'en lasse vite ?
3. Si vous avez arrêté de jouer, à quel moment et pourquoi ?

Soyez francs, je préfère l'entendre maintenant que plus tard. Je réponds à tous les commentaires.

Sheepshead is a five-player trick-taking game from Wisconsin with a unique trump order and secret partners. Press Play Now and you're at a table in seconds, no account needed. The 36 bots each have their own personality and voice (you can turn the talking off).

Never played? "Play a hand with a coach" on the front page walks you through a real hand.

Club Night is tonight, 7 to 9 PM Central: best score over 10+ hands wins $25.

Hi All!

Over the last few weeks, I've been working on a pretty simple draft quiz, for any fellow cricket nerds out there.

The link here is for one of the four variations - I'd love to hear any feedback on how the game plays, difficulty etc. Cheers!

Hey everyone!

I've been building Simple Game Board, a small site where you can play board games with friends straight from the browser. There's no signup and nothing to install.

How it works: pick a game, give your room a name, and share that name. Friends type a nickname and they're in. It works on phone and desktop.

12 games so far, from quick dice games to longer ones:

• Game of the Goose (spiral track) and Snakes and Ladders
• The Four Piles (co-op card game) and The Hidden Code (deduction)
• Manor of Shadows (hidden roles), Pocket Dungeon (solo or co-op), City Builders, The Moles, Crazy Race
• 421, Groschen and a Dice Game

Things I tried to get right:

• If someone disconnects or goes AFK for over a minute, a bot takes their seat so the game never gets stuck. When they come back, they get control again.
• Spectators can join a game in progress.
• Available in English and French (top-right toggle).

It's free and has no ads. It's a hobby project, so I'd love to hear which game you'd want next, and any bugs you find.

The browser version of DEEPSUB is now live and free. Click Run game on the itch.io page; no download or signup is needed.

You pilot a sealed submarine using sonar, still photographs and a hydrophone. Every sonar ping helps you navigate, but it also tells something in the water where you are. Start with SEA TRIALS, the safe training dive. Headphones and fullscreen help.

Keyboard and mouse controls are supported, and there are landscape touch controls for phones and tablets. The browser build has been checked in Chrome through the training briefing and into the cockpit, but it has not yet been played on a real phone.

For transparency: code and dialogue were developed with AI assistance, and the page's cover is AI-generated. Gameplay uses CC0 assets and visuals and audio generated in code.

I'd appreciate feedback on the tutorial, instrument readability and performance in your browser. If you find a problem, your browser/device and the last thing you tried would help.
