Make matches next to Jars to fill them with Paint. Once a Jar is Full, remove it by making matches with pieces of the same color as the Paint or with boosters.

❗️ The color of the Paint depends on the color of the pieces you've matched. For example, if you first matched blue pieces next to the Jar, then the Paint will be blue, and you'll have to remove it from the field by making matches with other blue pieces.
