Pairs
Find a pair in a row or in a column like this:
β¬β¬β¬β¬β¬β¬ β¬β¬β¬β¬β¬β¬ β¬β¬β¬β¬β¬β¬ β¬β¬β¬β¬β¬β¬ β¬π¦π¦β¬β¬β¬ β¬β¬β¬β¬β¬β¬and add opposite color next to them:
β¬β¬β¬β¬β¬β¬ β¬β¬β¬β¬β¬β¬ β¬β¬β¬β¬β¬β¬ β¬β¬β¬β¬β¬β¬ π¨π¦π¦π¨β¬β¬ β¬β¬β¬β¬β¬β¬
Triples
Find a same cells with an empty cell between them
β¬β¬β¬β¬β¬β¬ β¬β¬β¬β¬β¬β¬ β¬π¦β¬β¬β¬β¬ β¬β¬β¬β¬β¬β¬ β¬π¦β¬β¬β¬β¬ β¬β¬β¬β¬β¬β¬and add opposite color in the empty cell.
β¬β¬β¬β¬β¬β¬ β¬β¬β¬β¬β¬β¬ β¬π¦β¬β¬β¬β¬ β¬π¨β¬β¬β¬β¬ β¬π¦β¬β¬β¬β¬ β¬β¬β¬β¬β¬β¬
Incomplete lines
Find the rows and columns that have enough cells filled with one color
β¬β¬β¬β¬β¬β¬ β¬β¬β¬β¬β¬β¬ π¦π¨π¦β¬β¬π¦ β¬β¬β¬β¬β¬β¬ β¬β¬β¬β¬β¬β¬ β¬β¬β¬β¬β¬β¬and add opposite color in the empty cells.
β¬β¬β¬β¬β¬β¬ β¬β¬β¬β¬β¬β¬ π¦π¨π¦π¨π¨π¦ β¬β¬β¬β¬β¬β¬ β¬β¬β¬β¬β¬β¬ β¬β¬β¬β¬β¬β¬
Similarities
Find a similar line (row or column) that matches to another fully filled line
β¬π¦β¬β¬β¬π¦ β¬π¨β¬β¬β¬π¨ β¬π¨β¬β¬β¬π¨ β¬π¦β¬β¬β¬π¦ β¬β¬β¬β¬β¬π¨ β¬β¬β¬β¬β¬π¦and since no 2 lines can be the same, the empty cells should be filled with the opposite color.
β¬π¦β¬β¬β¬π¦ β¬π¨β¬β¬β¬π¨ β¬π¨β¬β¬β¬π¨ β¬π¦β¬β¬β¬π¦ β¬π¦β¬β¬β¬π¨ β¬π¨β¬β¬β¬π¦
Impossibilities
Find a line (row or column) where one is missing from color and if that color is placed on a specific cell, it will be impossible to fill the rest of the line, like:
β¬π¦β¬β¬β¬β¬ β¬π¦β¬β¬β¬β¬ β¬π¨β¬β¬β¬β¬ β¬β¬β¬β¬β¬β¬ β¬β¬β¬β¬β¬β¬ β¬β¬β¬β¬β¬β¬The bottom cell cannot be filled with blue because remaing 2 yellows will make a line of 3 yellows, so the bottom cell should be filled with yellow.
β¬π¦β¬β¬β¬β¬ β¬π¦β¬β¬β¬β¬ β¬π¨β¬β¬β¬β¬ β¬β¬β¬β¬β¬β¬ β¬β¬β¬β¬β¬β¬ β¬π¨β¬β¬β¬β¬
