Start the mill in the game Spin Hue. Its blades are a circle divided into four sectors of different colors and sizes: blue, green, red and yellow. Bags of the same colors will fall onto the mill from above. To accept a bag, turn the wheel so that the bag lands on the sector of the corresponding color. If this does not happen, the mill will stop and the Spin Hue game will end. Each caught bag is worth one point.
