Pixel Color Flow is a fun, satisfying color matching puzzle game where you clear a board of pixel cubes by sending cute pigs onto a conveyor. 
Each pig drops balls onto only the cubes of the same color, so your main challenge is choosing the right order and managing the queue to clean the board efficiently.

Every pig has an ammo count (shown as a number above its head). When it runs out, the pig leaves. If ammo is still left, the pig can move into one of 5 waiting slots, ready to be sent again when you tap. The conveyor also has a capacity limit, so smart timing matters don’t overflow it.

Check the pixel board and spot which colors need clearing first.
Tap a pig to send it onto the conveyor.
The pig will shoot/drop balls automatically onto matching color cubes only.
Watch the ammo number above the pig each shot uses ammo.
When ammo becomes 0, the pig leaves the run.
If it still has ammo, it can move into one of 5 waiting slots.
Tap again to send pigs from the waiting slots back onto the conveyor.
Manage the conveyor capacity (if it’s full, you must wait).
Keep repeating until you clear all cubes and complete the level.
