### 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¬
