Like Wordle, but with blocks.
One daily sequence. Same pieces for everyone. Only your best run counts.
Free, no ads, and built for your phone.

What it is

Swipetris is a mobile-first PWA built around one-thumb controls:

• Drag to move
• Tap to rotate
• Flick down to drop
• Play the same seeded piece sequence as everyone else each day
• Submit your best run to the daily arcade leaderboard
• Install it to your home screen and play offline

There are no accounts, ads, cookies, tracking, or product analytics. Gameplay stays local; only leaderboard requests and score submissions send game data to the Swipetris server.

Stack

• The game is rendered with three.js in public/app.js
• The play UI uses Alpine.js in public/play.html
• Landing-page motion is mostly CSS; the phone demo is driven by public/landing.js
• Local development runs on Bun and Hono
• Production is static Cloudflare Pages plus dependency-free Pages Functions
• Scores are stored in Turso

Generate the brand image

The README lockup is rendered from the landing-page .brand-lockup with Vercel Satori:

bun run generate:brand

This updates public/brand.svg and public/play-button.svg from the brand and CTA markup in public/index.html.

Run locally

Requirements: Bun 1.2 or newer.

git clone https://github.com/bitbonsai/swipetris.git
cd swipetris
bun install
bun run dev

Open http://localhost:3000. Without environment variables, the server creates a local swipetris.db SQLite database.

To use Turso instead:

cp .env.example .env
# Fill in TURSO_URL and TURSO_TOKEN
bun run dev

Careful: a Turso-backed local server writes to that remote database. Use a development database unless you intentionally want to write to production.

Test the Pages deployment locally

cp .env.example .env
bunx wrangler pages dev public

Wrangler serves public/ and loads the routes in functions/api/. The Pages Functions intentionally use the raw libSQL HTTP API and have no npm imports; this repository has no production build step.

Deploy

1. Create a Turso database and apply schema.sql, for example with turso db shell <database> < schema.sql.
2. Create a Cloudflare Pages project connected to your fork.
3. Leave the build command empty and set the output directory to public.
4. Add TURSO_URL and TURSO_TOKEN in the Pages project settings.
5. Deploy the main branch.

Cloudflare discovers functions/ automatically. Environment-variable changes only apply to new deployments.

Leaderboard trust model

Scores are untrusted client input. The API validates payload shape, daily seeds, score plausibility, timing, and submission rate before storing a result. These checks discourage casual abuse; they are not cryptographic proof of gameplay. Production operators should also configure platform-level rate limiting and monitor anomalous scores.
