The main goal of Stack Colors is to collect elements of a specific color and put as many elements on the bottom line as possible. Your character is controllable, and its color also affects the color of the things you need to pick up. In addition, you should not pick up things with other colors because picking them up will cause you to lose color; sometimes you will lose all of them. In certain situations, colors can change quickly, and you need to react quickly to find the right object. It is a simple but challenging game with a harmonious and colorful interface that provides a comfortable visual experience for players.
