Play Little Alchemy classic together: every discovery syncs live between friends, peer-to-peer. LITTLE ALCHEMY CO-OP Play Little Alchemy Classic together with friends. Little Alchemy Co-op is a Open Source browser extension that adds real-time multiplayer to the official Little Alchemy Classic game. Tested in Chrome and Firefox. Other Chromium-based browsers such as Edge and Brave use the same build. Source at: https://github.com/Der-Floh/LittleAlchemy-OnlineCoop KEY FEATURES • Shared discoveries Everything one player discovers appears in everyone else's game within about a second — including the library, element counter, and save progress. • Shared canvas Everyone sees and plays on the same workspace. Elements, movements, and combinations are synchronized between players, and you can see where everyone else's cursor is. • Catch-up activity Returning to a room after being away? A catch-up card shows what the other players discovered while you were gone. • Host controls The host can lock the room, remove players, or transfer the host role to someone else. HOW IT WORKS The extension runs on top of the official Little Alchemy game at: https://littlealchemy.com/ There is no game server to run. Players connect directly to each other using WebRTC via PeerJS. PeerJS: https://peerjs.com/ HOW TO PLAY 1. Install the extension and open: https://littlealchemy.com/ 2. Click the Co-op button in the top-left corner. 3. Select Create room. 4. Send your friend the 6-character room code, or click Invite link and send them the generated link. Example: https://littlealchemy.com/#coop=K7M4PX 5. Your friend can open the invite link or enter the room code under "or join a friend." 6. Start playing. Whenever someone discovers something new, you'll see a pop-up. The Activity list also shows who discovered what. SHARED CANVAS • Anyone can move or combine any element. • While someone is dragging an element, it is outlined in their colour and shows their name. Nobody else can grab it or drop another element onto it at the same time. • Everyone sees the same arrangement, automatically fitted to their own window. Elements won't end up off-screen or hidden behind the library just because another player has a different screen size. • The game's Clear button removes only the elements that you placed or created. • Other players' cursors can be hidden under: Settings → Show other players' cursors PROGRESS AND SAVES Progress is merged both ways. When you join a room: • Everything you already discovered is added to the room. • Everything the room has discovered is added to your save. • Those discoveries remain in your save permanently. The first time you ever join a room, the extension creates a one-time backup of your save. You can restore it after leaving the room under: Settings → Restore backup ROOMS • A room stays alive as long as at least one player is in it. • If the player who created the room leaves, another player automatically becomes host. • If everyone leaves, nothing is lost. Each player's save still contains everything that was discovered. • Joining the same room code later opens the room again. • Rooms support up to 8 players. GOOD TO KNOW • Joining a room replaces your current canvas with the room's canvas. Your discovery progress is not affected, and elements can always be dragged from the library again. • Reloading the page automatically rejoins your room. • Choosing Leave room stops automatic rejoining. • Use one Little Alchemy tab at a time. If you open a second tab, it stays passive until you select "Use co-op in this tab." VERSION COMPATIBILITY Everyone in a room needs version 0.2 or later. Version 0.2 introduced a new connection protocol, so version 0.1 cannot share a room with newer versions. If incompatible versions try to connect, the extension will tell you. Versions 0.2 and newer can play together. HOST CONTROLS The current host gets additional controls in the Players list: • Lock room Prevents new players from joining. Players who were already in the room can still reconnect. • Kick Removes a player from the room. That player cannot rejoin until the room has completely emptied. • Make host Transfers the host role and host controls to another player.
