BattleBlocks AI: a block duel where one builds and one chooses
BattleBlocks AI is an asymmetric falling-block duel we are building in public. One player is the Builder: climb to a target height, recover below it, then hold the stack. The other is the Chooser, who picks each next piece from a hand of six. In the full game the roles swap in round two.
What exists today is checked engine work, not a game you can try yet: a Rust rules foundation with checked motion, geometry, replay and objective rules (30 selected objective cases passed across native Rust, WASM and Chromium in CI), and a small Builder-only sandbox that has run in an Android emulator. The site, the devlog and a signup for build updates are open.
We've entered Colosseum's Crypto World's Fair and Solana Mobile's CLOCK IN hackathon. The cut we are aiming at is a one-phone practice round against a labelled practice bot, with wallet connection through Mobile Wallet Adapter and an optional devnet memo. These are plans; none of it has run on a phone yet.
Want to test the first phone build when it exists? Sign up for early access on the site and we'll email you.
