How can I simplify my game to avoid it from taking larger memory as the running time increases?

问题遇到的现象和发生背景

This is a color-flipping game based on the python turtle module. The game is composed of a rectangular board divided into a number of flat colored tiles of various colors. The goal of the game is to turn all tiles to the same color by choosing one tile on the board and then changing its color to another color. The newly selected color will spread to all its neighboring tiles which match the original color of the chosen tile. The player continues selecting another tile and changing its color to another until all the tiles within the board flipped to the same color. In addition to the rectangular board, an array of colors is shown below the board. These are the colors to which the player can choose to flip the color of the selected tile.

As I started to run my game, the memory it took up was getting larger and larger as the running time increased. And it's getting slower and slower. I think it might be due to the while loop at the end of my code. But I'm not sure. How can I modify it to make it faster?
