The Honey Stack adds a new layer of challenge by restricting block movement within it. Once a block is placed in this column, it becomes locked and cannot be moved. The first block placed determines the color for the entire column, and only blocks of the same color can be added.
To complete Honey Stack, you must fully fill it with matching blocks. However, since blocks cannot be removed once placed, careful planning is required to avoid mistakes that could limit your sorting options.
This mechanic encourages players to think ahead and strategize their moves more effectively. Properly managing Honey Stack can help clear blocks efficiently and create more space on the board, making it a key element in solving more complex levels.
