About Rubble Kings

In Rubble Kings, land comes from height. You stack physics-based blocks into a kingdom, and the taller your structure stands, the more territory you control. Building upward is the way to expand, so a match comes down to how ambitious you are willing to be with your tower.

The creator remembered a similar game from more than twenty years ago but could never recall its name or track it down, so they built their own with Claude Code and Three.js.

The physics is where the strategy lives. A tall tower claims more land but is easier to topple, and one well-placed hit from a rival can bring the whole thing down. Rivals try to knock your tower over while you go after theirs, so stability matters as much as size.
