Moves

Understanding exactly how tiles move is crucial for planning your strategy in 2048.

Movement Mechanics

When you make a move:

1. The game processes all tiles simultaneously
2. Each tile calculates its destination
3. Merges happen during movement
4. All animations play
5. A new tile spawns

Order of Operations

For a leftward move, the game processes tiles from left to right, row by row:

1. Check the leftmost position for each tile
2. If blocked by same-value tile, merge
3. If blocked by different tile, stop one position away
4. If path is clear, slide to the edge

Movement Examples

Simple Slide

Before (moving left):

| empty | empty | 2 | empty |

After:

| 2 | empty | empty | empty |

Simple Merge

Before (moving left):

| 2 | 2 | empty | empty |

After:

| 4 | empty | empty | empty |

Multiple Merges

Before (moving left):

| 2 | 2 | 4 | 4 |

After:

| 4 | 8 | empty | empty |

Both pairs merge independently.

Three of a Kind

Before (moving left):

| 2 | 2 | 2 | empty |

After:

| 4 | 2 | empty | empty |

Only the leftmost pair merges because tiles can only merge once per move.

Four of a Kind

Before (moving left):

| 2 | 2 | 2 | 2 |

After:

| 4 | 4 | empty | empty |

Two merges happen: positions 1-2 and positions 3-4.

Blocked Tiles

A tile stops moving when it hits:

1. The board edge — No further movement possible
2. A different-value tile — Can't merge, stops adjacent
3. A same-value tile that already merged — Tiles only merge once per move

The "Once Per Move" Rule

This is critical for advanced play:

• A merged tile cannot merge again in the same move
• This prevents chain reactions within a single move
• Use this to your advantage when planning

Example: Moving left with 4 | 2 | 2 | empty

1. The 4 slides to the left edge
2. The two 2s merge into a 4
3. The new 4 stops next to the original 4 — it cannot merge again

Result: 4 | 4 | empty | empty

Valid vs Invalid Moves

A move is valid only if something changes:

Valid moves:

• At least one tile slides
• At least one merge occurs

Invalid moves (nothing happens):

• All tiles already at target edge
• No tiles can merge or slide

Invalid moves don't spawn new tiles.

Directional Strategy

Each direction has strategic implications:
