In "Poppy stack colors", the objective is to build the tallest pillar possible by collecting and stacking platforms of different colors. Each level of the game presents a unique combination of platform colors, and the player must choose the correct ones to build a stable pillar.

To collect the platforms, the player moves a character left and right on the screen using arrow keys or touch controls. When the character touches a platform, it attaches to the character's feet and can be moved around. The player must carefully navigate the character to the correct platform colors and bring them to the center of the screen, where the pillar is built.

Once the player has stacked all of the available platforms, they can initiate the "Kick" phase by pressing a button. The character will then kick the pillar, attempting to knock it over and score points based on the height of the tower. However, if the tower is not built correctly, it may collapse before the kick phase begins, resulting in a failed attempt.

As the player progresses through the levels, the game introduces new challenges such as moving platforms, limited time, or additional hazards that can cause the tower to fall.

It's a fun and engaging game that tests the player's color recognition, problem-solving skills, and timing. Will you be able to build the tallest tower and score the most points? Play "Poppy stack colors" to find out!
