About the game

Drag two element cards together to craft something new. A pair someone's already made gives you its known result, while a pair nobody's tried yet becomes a brand-new item. Playing as a guest sets up a real account with no forms and no download.

Four base elements at the root of a growing crafting tree. Permanent credit for first discoveries. Serial-numbered copies, each with rarity locked in when minted. A 1v1 duel race against a friend. The Infinite Canvas, a lasting shared world of player-owned plots. Free recrafting of anything already discovered. Daily allowance of new inventions, topped up with coins.

For a duel, share a four-letter room code with a friend, then race to craft a secret target that neither of you has made, starting from the base elements. In the Commons, drag your card onto someone else's to co-craft the outcome for both of you.

The game's FAQ says Claude by Anthropic invents each new item the first time someone makes it, writing its name and lore and drawing its 32×32 pixel-art card.

Questions

Can I play Omnicrafter with friends?

Yes. It has online multiplayer, so friends can join from their own computer without being in the same room. It isn't listed for phones, though.
