Mix and pair up matching 'Kullors' to clear the levels!
You sometimes need to mix 'Kullors' to get the right color for pairing up. Click on a Kullor and move the mouse over others to see the possible outcome of a color mix. Red green and blue can be mixed to cyan yellow and magenta and vice versa. The more you mix the more you will score.
Refer to the color chart. You may come across some special colors, stars and items:
Black and white when mixed will cause a color shift around the color wheel. Shiny stars will hunt down and eliminate any Kullor matching that which it touches. Rainbow stars will hunt down and alter the color of any Kullor matching that which it touches. Clocks will add time to your remaining level. Be sure to collect them.
