Rubble Kings

What it is

Rubble Kings is a physics strategy game by eric_j_sexton, played in the browser. You stack gravity-bound blocks into a castle, building your kingdom ever higher while trying to bring your rivals' towers down. The menu has Play, Join and Credits, so you can join other people's matches. The blocks follow physics and can collapse, which sets it apart from most strategy games. According to the AI game catalog GamesByAI, most of the game was made with AI; the listing comes from the Vibe Jam 2026 submission form and names Claude Code as the tool.

Who it's for: People who love stacking blocks and watching things come crashing down.

Before you start: The page opens without a login or payment prompt; the author doesn't say whether the full game is free. When we checked, the page was labelled "pre-production smoke test", meaning it's a very early test build and may be unstable. The catalog marks it as an online game. There's no word on phone support, menus are in English, and there's no age rating.
