Tactveil

Modern hidden-information strategy game. Pure client-side. Works offline. Installable PWA.

Inspired by classic 10x10 tactics games with hidden ranks, but fully original in design, visuals, and implementation.

Live demo: https://tactveil.vercel.app (or the latest deployment from the repo)

Tech

• Svelte 5 + SvelteKit 2
• Pure framework-independent TypeScript game engine in src/lib/game/
• Vitest + Playwright
• @sveltejs/adapter-vercel
• No server game state
• Service worker for offline assets
• Web Worker ready for AI

Development

npm install
npm run dev
npm run build
npm run test
npm run test:ui   # if configured

Architecture

The game engine is completely decoupled:

• All rules, movement, combat, victory, and state transitions live in pure TS functions.
• Svelte only consumes projections (getPublicGameView) and dispatches validated actions.
• Hidden information is never present in the rendered DOM, ARIA, classes, or serialized public state.

See src/lib/game/ for the engine and src/lib/stores/game.ts for the Svelte integration.

Status

• Pure engine complete (movement, combat, setup, serialization, projections)
• SvelteKit UI: interactive CSS Grid board with original-style glyphs, manual setup + counts, full click-to-play, handoff, modals, modes (single+3-level AI, passplay, training all-visible)
• Basic audio, save/load, PWA manifest + SW
• Build + deploy ready with @sveltejs/adapter-vercel
• Next: deeper AI, tests, iPhone polish, deploy

All per original multi-agent spec. Playable from setup to victory.

All previous requirements (client-only, no backend state, iPhone friendly, original assets) remain in force.
