To play, tap a space to flip the colors of spaces according to the game pattern. The pattern can contain the space you tap, but some patterns don’t follow this rule. The purpose of the game is to get all spaces on the board to be the same color.
One strategy is to start from the top and change all the colors to be the same from top to bottom. This will leave a combination of colors in the bottom row. From here, toggling a single space in the top row and tapping from top to bottom again will change a set of the colors in the bottom row. Figure out which bottom row spaces are changed from each of the top space to win the game!
