A Minecraft-style multiplayer block world that went viral on X with 7.4M views: one link is one shared live world — post it and everyone who opens it builds together in the browser, no download or account needed.

A free browser-playable fantasy card game where you build a deck from two of eighteen mix-and-match realms, with 800+ cards and AI, hot-seat and ranked modes.
Shattered Realms is a free digital card game in the spirit of Hearthstone. The world broke into eighteen realms, and you build your deck from one or two of them. Each realm plays differently: Vampires pay their own Health for power, Lycanthropes switch between human and beast forms, Aliens splice enemy minions into hybrids, Zombies keep coming back from the dead, and the Void gets stronger when your hand is empty. Any two realms combine, and every pairing has its own Fusion spell and hero portrait. It has over 800 cards, including 44 legendaries, plus expansions that unlock as you play. You can play against the AI (five difficulty levels), hot-seat with a friend on one device, or ranked online. The creator notes the card art is AI-generated and the code was written with an AI coding assistant (Claude) from their designs; there are no ads and no purchases.
