In the offline puzzle game Makes 9: Merge Ups, players combine numbered tiles to form the number 9. Because tiles emerge on a grid and must be combined in the right order, the gameplay emphasizes strategy and meticulous planning. Tiles can be combined by swiping or dragging them, and each successful merge creates room for new tiles. As the grid gets more crowded and there are fewer moves available, it becomes harder to avoid being trapped. Occasionally, special tiles or bonuses show up to help in merging or clearing space. The goal is to keep combining tiles in order to get better points while keeping the grid from filling up entirely. It is skill-based, strategic, and captivating due to its straightforward controls and captivating puzzle elements.
