How to Play & Instructions
1. Core Objective
Use arrow keys or swipe gestures to move all tiles across the 4x4 grid. When two tiles with the same number collide, they merge into one tile with their sum value!
2. Corner Strategy
Keep your highest number tile firmly anchored in one corner (e.g., bottom-right) and build a descending numerical chain along the edge for maximum longevity.
3. Keyboard & Touch Controls
Desktop supports Arrow Keys and WASD. Mobile supports smooth touch swipe gestures. Click "Restart" anytime to initiate a fresh session.
