Show HN: InfiniDomino – practically infinite world of dominoes to knock over

InfiniDomino is an online, real-time shared world that maps a virtually infinite grid where every square holds a single domino. Players anywhere can click a standing domino to topple it and set off chain reactions that propagate according to each tile’s facing; hits from behind or the side follow the domino’s orientation, while frontal hits can knock pieces backward. Fallen dominoes can be clicked to stand back up (but not while they’re actively falling), so players can revive running chains by restoring pieces ahead of a wave or clearing debris behind it. The interface tracks live stats - online users, currently falling, currently down, and all-time toppled including your personal count - and displays a glowing arrow to show fall direction.

Navigation and interaction prioritize quick movement around a massive table: drag, WASD/arrow keys, scroll/pinch to zoom, right-drag or Shift+drag and Q/E to rotate, and R/F to tilt. Quick actions include J to jump to the next active chain, G to jump to a coordinate, Enter or click to topple, M to toggle sound, and H for help. The address bar encodes position so you can share views directly; controls also support touch gestures and keyboard focus for accessibility, making it easy to find and follow interesting cascades in a persistent communal sandbox.
