Slay (web)

A browser remake of Sean O'Connor's Slay: a turn-based hex strategy game. Play against bots; the engine is pure and serialisable so multiplayer can be added later.

Run

npm install
npm run dev      # development server
npm run build    # type-check + production build into dist/
npm test         # engine, AI and UI unit tests (Vitest)

Pushes to main build and deploy automatically to GitHub Pages via .github/workflows/deploy.yml (requires repo Settings → Pages → Source set to "GitHub Actions").

How to play

• Click a hex of yours to select its territory. The top bar shows its gold, income (1 per hex without a tree) and wages (Peasant 2, Spearman 6, Knight 18, Baron 54).
• Click a fresh unit to pick it up; highlighted hexes are legal moves. Moving inside your territory is free; cutting a tree or capturing an enemy hex uses the unit's move for the turn.
• A unit captures a hex only if its strength (1–4) beats the defence: the strongest of the enemy's unit, castle (2) or capital (1) on that hex or on the hexes around it.
• Buy peasants (10) and castles (15) with the buttons; place them on a highlighted hex. A peasant can be placed directly onto an undefended enemy hex. Merge two units to build stronger ones (max Baron).
• If a territory cannot pay its wages, every unit in it dies. Capturing a capital destroys its treasury.
• Win by leaving no other player with a territory of two or more hexes.

Layout

• src/engine — rules as a pure reducer (applyAction), map generation and presets. No DOM.
• src/ai — planTurn(state, difficulty) returns the bot's actions.
• src/ui — canvas renderer, HUD, screens, autosave.
• docs/superpowers/specs — design spec; docs/superpowers/plans — implementation plan.
