🎮 GAME CONTROLS

• ⌨️ KEYBOARD INPUT
  Press the **Arrow Keys** (Up, Down, Left, Right) or standard **W, A, S, D** keys to slide all active tiles across the grid columns.
• 🖱️ MOUSE & SWIPE TOUCH
  On mobile and tablet viewports, perform **swipe gestures** (up, down, left, right) directly on the grid area. On desktop screens, you can click and drag-swipe tiles using your mouse pointer.
• ⚙️ PANEL ACTIONS
  Use the **Undo Move** button to step back, or scrub the **Time-Travel Slider** to scroll backward through your history stack of previous moves.

🔢 CORE SLIDING RULES

• MERGING MATH
  Tiles with matching numbers double in value when merged (e.g. 2 + 2 = 4, 4 + 4 = 8, ..., 1024 + 1024 = 2048). Tiles can only merge once per direction swipe.
• RANDOM SPAWNS
  After every slide that changes the board, a new tile spawns in an empty square. It has a 90% chance of being a 2, and 10% chance of being a 4.
• GRID GOALS
  Different sizes scale your targets: 3x3 is Hard (1024 target), 4x4 is Classic (2048 target), 5x5 is Relaxed (4096 target), and 6x6 is Mega (8192 target).

💡 CORNER STRATEGY & TACTICS

• CORNER ANCHOR
  Always anchor your highest-value tile in one of the bottom corners (e.g., bottom-right). Never swipe UP unless you are forced to, to prevent tiles shifting.
• GRADIENT ORDER
  Maintain a descending chain gradient leading to your corner (e.g., [128, 64, 32, 16] along the bottom row). This sets up rapid merge reactions.
• AI RECOMMENDATION
  Toggle the AI Advisor if you get stuck. The solver runs look-ahead trees assessing monotonicity and empty cells to find the safest branch.
