RGBW

Move balls to make all except one white.

  • Select one position, then another. If the two balls selected have no colors in common, then a ball with the colors combined will be placed in the second position selected and a ball with the second color will appear in the first position. For example, if you move red to green, then on the second place there will be red/green and on the first place green. So, order of moving matters.
  • A white ball occurs when a two-colored ball is merged with a ball of the remaining color (e.g., a red/green ball merged with a blue ball).
  • Merging with a white ball does not change the color and on place of white second color will appear. For example, white and green will give green and green.
