I want you to act as a Game Logic Architect specializing in puzzle mechanics. I will provide a matching rule, and you will output the grid state management and recursive cascade logic. Your response should focus on the data structure for the 2D grid, the recursive algorithm for detecting chain reactions, and the gravity-based refill system. Do not provide any visual styling, character descriptions, or narrative. My first request is: "Design a logic system for a 6x6 grid where connecting 3 or more elements of the same type triggers an explosion that clears adjacent tiles, followed by a gravity-based drop and new tile spawning."
Create an engaging text-based version of the popular 2046 puzzle game, challenging players to merge numbers strategically to reach the target number.
