BLOCK BLAST

A premium neon puzzle game built entirely in Flutter — drag blocks, fill rows & columns, blast them away in a storm of particles. One codebase. Four platforms.

Flutter 3.x Dart 3 · Null Safe Android iOS Windows Web Download Now <!~~- Mini block grid visual -~~>

<!~~- ════════════════════════════════════ QUICK STATS -~~> <section> 8×12 Game Grid 4 Platforms 9 Unique Sounds ∞ Levels 0 Audio Files 0 Permissions </section>

What Makes This Special Block Blast is not just another puzzle game template. It features a custom procedural audio engine (no audio files!), a particle explosion system, smooth neon aesthetics, and a clean layered architecture — all in one ready-to-publish Flutter package.

<!~~- ════════════════════════════════════ FEATURES -~~> <section> Core Features Everything You Need — Out of the Box

No extra integrations, no broken dependencies. Build and run immediately on any platform.

</section> Smooth Drag & Drop Blocks float above the finger just like real Block Blast games. Ghost indicator shows exactly where the piece will land — green for valid, red for invalid. Particle Explosion System Every line clear triggers a burst of colored particles flying outward, plus a screen shake effect. Built with a custom painter — no external physics library needed. Procedural Audio Engine 9 unique sounds + looping background music — ALL synthesized mathematically in Dart. Zero audio asset files. Keeps your APK lightweight and deployment friction-free. Premium Neon UI Deep dark background, electric color palette, glow effects, animated level progress bar, combo pop-ups, and score animations. Orbitron font throughout. Combo & Level System Combo multiplier rewards consecutive line clears. Every 1,000 points triggers a level-up with fanfare. Best score persists locally via SharedPreferences. ⚙️ Clean Architecture Neatly separated into models, screens, widgets, and utils. No spaghetti in main.dart. Easy to extend, rebrand, or hand off to another developer.

<!~~- ════════════════════════════════════ AUDIO -~~> <section> Audio Engine 9 Sounds + Music — Zero Files

All audio is generated using pure Dart math (sine waves, noise, envelopes). No MP3s, no OGGs, no asset pipeline headaches.

</section> Block Pickup Click Placement Thud Invalid Placement Buzz Line Clear Blast Big Blast (Multi-line) Combo Arpeggio Mega Combo Sweep Level-Up Fanfare Game-Over Melody BG Music Loop How it works The AudioService singleton synthesizes WAV bytes using Dart’s math library (sin, exp, noise). It encodes them as 16-bit PCM WAV in memory and plays via audioplayers. Background music loops automatically via the onPlayerComplete listener.

<!~~- ════════════════════════════════════ PLATFORMS -~~> <section> Multi-Platform One Codebase — Four Platforms

Flutter handles platform-specific rendering. You get native performance on every OS with zero platform-specific code.
