2048 Game Development Prompt: Professional Stable Edition

Objective

Create a high-performance, mobile-optimized 2048 game in a single HTML file. The goal is “Industrial-Grade Smoothness”—zero flicker, state persistence, and polished mobile UX.

1. Visual & Layout Architecture

Coordinate System:
- Tiles MUST use position: absolute.
- Movement MUST be handled via transform: translate(x, y) using CSS calc().
- Formula: transform: translate(calc(col * (100% + gap)), calc(row * (100% + gap))).
Zero-Flicker Injection:
- When a new tile is created, its transform coordinates must be calculated and set before it is appended to the DOM to prevent “top-left corner flashing.”
Mobile-First CSS:
- Body: padding-top: 5vh to pull the game down from the notch/status bar.
- Container: touch-action: none and overflow: hidden to disable browser pull-to-refresh and scrolling.
- Layout: Center the game board horizontally.

2. Persistence & State Management

Auto-Save: After every move and new tile generation, serialize the 4x4 grid (tile values) and current score to localStorage.
Session Recovery: On page load, check for saved data. If found, rebuild the grid silently (disable the “appear” animation for recovered tiles) so the player can continue exactly where they left off.
Score Tracking: Maintain “Current Score” and a persistent “Best Score.”

3. Core Logic & Animation Sync

Atomic Move Sequence:
1. Calculate: Map out all tile destinations.
2. Visual Slide: Update transform for all moving tiles (including those marked for deletion).
3. Delayed Cleanup: Remove merged tiles from the DOM only after the 150ms transition ends.
4. Merge Pop: Trigger a 1.15x scale pulse on the new tile AFTER the sliding tiles overlap.
Animation Lock: Use a lock flag to ignore inputs for 200ms during active animations.
Win/Loss Detection:
- Win: Detect value 2048 and show a “You Win” overlay.
- Loss: If the grid is full AND no adjacent tiles (horizontal/vertical) match, show a “Game Over” overlay.

4. Interaction & UX Polish
