letter-rivals

Letter Rivals is an original mobile-first pocket word duel for Poe. Build local-dictionary words from your private rack, race a lightweight bot rival, and chase premium-square bursts on an 11×11 board designed for small feed iframes.

What ships in this first release:

• Original non-branded identity, colors, copy, and art direction.
• Durable synced-store game state: public board, public score/turn/event stream, private player rack/pending move, server-only rival rack and tile bag.
• Local deterministic pocket dictionary in logic/dictionary.ts; the included words are hand-curated common English playtest words for prototype QA and avoid external licensing requirements.
• Opening center-star rule, row/column placement, gap checks, adjacency checks, cross-word scoring, double/triple letter and word premiums, pass/exchange/new-game controls, terminal state after passes or final rack.
• Tactile mobile UI with haptics where supported, no text selection, reduced-motion support, and fast retry.

Multiplayer note: the data model keeps hidden racks and bag out of public state and is ready for async human turns. This release intentionally uses a bot rival so the app is immediately tryable in a single Poe session without faking multiplayer or leaking opponent tiles.
