Every block has a way out. Find it.

KABLOCK is a sliding-block puzzle with one beautifully simple rule: drag a block to a gate of the same colour and it's gone. Sweep the gems on the way through. Clear the board. Then do it again on a board that's just a little harder.

It never plateaus. Most puzzle games run out of ideas by level 50. KABLOCK's difficulty climbs forever — mathematically guaranteed to keep rising and still be solvable, whether you're on level 12 or level 12,000.

Learn by playing, not by reading. Ten hand-built opening levels teach you the whole game one idea at a time — no wall of tutorial text, no way to fail.

The Daily Puzzle

One board. The same board for every player on Earth. One attempt. Get graded against par, then share your result — spoiler-free, so nobody spoils it for anyone else.

Six ways to play

Mode	What it is
Classic	Relaxed. No clock, no fail state.
Timer	Solve as many as you can before the clock runs out.
Endless	The ladder climbs faster and never stops.
Extreme	Denser boards, less room to think.
Run	One life. See how far you get.
Nightmare	Good luck.

Plus Fun Mode, a pure sandbox where you set the difficulty dial and nothing is ever scored — and Cascade, a whole second game: fill the 8×8 grid, clear lines, and watch gravity chain the clears together.

Power when you need it

Bank rockets to blow a stuck board wide open. Shields, XP boosts and time-stasis for when a run gets tight. Keep a good run alive with a continue.

Play the long game

Build a daily streak. Chase 60+ achievements. Ascend to trade your level for permanent cores that make every gem you ever earn worth more. And every clear rolls for a surprise drop — you never know when the jackpot lands.

Make it yours

Four board skins, five backgrounds, five colour themes, ten soundtracks, and a full accessibility pass: Calm mode, reduce-motion support, high contrast, and haptics you can switch off.

About this repository

⚠️ This repo contains the compiled Flutter web build, not source code. main.dart.js is a ~3 MB minified bundle produced by flutter build web. The Dart source (lib/, pubspec.yaml, …) lives in a separate private repo.

Path	Purpose
index.html	Entry point / app shell
main.dart.js	Compiled app code (minified)
flutter.js, flutter_bootstrap.js	Flutter web loader
flutter_service_worker.js	Cache kill-switch (see below)
canvaskit/	CanvasKit WASM renderer
assets/	Fonts (Inter, Space Grotesk), shaders, asset manifests
icons/, favicon.png, icon.svg	App icons
manifest.json	PWA manifest

The live site is served from the gh-pages branch.

Run it locally

Serve the folder over HTTP — opening index.html directly won't work, it needs a server:

python3 -m http.server 8000

Then open http://localhost:8000.

A note on caching

The build ships with --pwa-strategy=none and a deliberately self-destroying service worker: on activate it clears every cache, unregisters itself, and reloads open tabs. Flutter's default offline-first worker used to leave returning players stuck on a stale build, and this is the fix. KILL_VERSION is bumped on every deploy so returning devices re-run it.
