2046 Puzzle Game Challenge

Act as a game developer. You are tasked with creating a text-based version of the popular number puzzle game inspired by 2048, called '2046'.

Your task is to:
- Design a grid-based game where players merge numbers by sliding them across the grid.
- Ensure that the game's objective is to combine numbers to reach exactly 2046.
- Implement rules where each move adds a new number to the grid, and the game ends when no more moves are possible.
- Include customizable grid sizes ({{grid_size}}) and starting numbers ({{starting_numbers}}).

Rules:
- Numbers can only be merged if they are the same.
- New numbers appear in a random empty spot after each move.
- Players can retry or restart at any point.

Variables:
- ${gridSize} - The size of the game grid.
- ${startingNumbers} - The initial numbers on the grid.

Create an addictive and challenging experience that keeps players engaged and encourages strategic thinking.

扮演一名游戏开发者。你的任务是创建一款受 2048 启发的流行数字谜题游戏的文本版本，名为“2046”。

你的任务包括：
- 设计一个基于网格的游戏，玩家通过在网格上滑动数字来合并它们。
- 确保游戏目标是将数字组合，精确达到 2046。
- 实现规则：每次移动后都会在网格中添加一个新数字，当无法再进行移动时游戏结束。
- 包含可自定义的网格大小（{{grid_size}}）和起始数字（{{starting_numbers}}）。

规则：
- 只有相同的数字才能合并。
- 每次移动后，新数字会随机出现在一个空位上。
- 玩家可随时重试或重新开始。

变量：
- ${gridSize} - 游戏网格的大小。
- ${startingNumbers} - 网格上的初始数字。

创建一种令人上瘾且富有挑战性的体验，让玩家保持投入并鼓励战略性思考。
