spinlings

Tiny pixel creatures that battle above your prompt while Claude works.

Spinlings is a creature card game that lives inside Claude Code. While Claude works, wild creatures rustle into a slim band above the prompt and your team of three battles them. Win, and you might catch one. Every card is one of a kind, with its own look, genes and traits. You can fuse two cards into a hybrid nobody has seen before, trade, sell or gift cards to other players, challenge them to duels and climb the global leaderboards.

The world lives at spinlings.dev, or entirely on your machine if you play offline.

Your team is ready. Start with three creatures and a random handle like `soft-otter-42`. A passkey brings your collection to another computer. Battles play themselves. Your creatures fight while Claude works. Press 1 when a special fires for a Perfect hit. Playable alone. Generated Rivals and a Wandering Trader fill in whenever no other player is around, so the game works on day one. Free. Nothing to buy, and cards have no cash value. Open source (MIT), mod and server.
