Color Fall is a pull-the-pin, logic-puzzle game similar to ball-in-cup and water-in-glass games. The player must pull one or more golden pins to drop one or more colored liquids into waiting delivery trucks across 30 levels.
The game displays the liquid or liquids in funnel-like hanging, white-framed storage areas. The matching truck or trucks wait at ground level. A colored liquid is suspended atop or against a golden pin. The position of the liquid depends entirely on the angle of the pin. The game uses horizontal, vertical and diagonal pin placement.
The player's goal is to determine the correct order of pin displacement steps to take to drop the liquid or liquids into the waiting truck or trucks. For example, they might need to pull a horizontal pin, wait for a liquid to drop as balls of fluid into a matching truck, wait for the truck to drive away, and then pull a pin or pins to drop other liquids.
Color Fall presents the player with many obstacles. For example, black liquid eliminates all colored liquids. As a result, the player must transfer it into areas that don't hold colored liquids and clear paths between colored liquids and the trucks. Additionally, they might need to block a path with a pin or use a pin to push liquid into a specific area. In these scenarios, they slide instead of pull pins.
When the player does well, the game shoots a burst of confetti across the screen. It then unlocks the next level. It doesn't penalize the player if a couple of liquid balls disappear or fail to fall into a truck.
