Full House: Fill the Last Empty Cell
Also called the last free cell. It is the first technique most players learn.
When a row, a column, or a block has just one empty cell, only one color can go there. Count the colors already in place, and the missing one is your answer.
1
Find a block with one cell left
BEFORE
Look for a row, a column, or a block that is almost full. This block has eight bubbles and one empty cell. Read the colors already here: Red, Yellow, Dark Purple, Light Green, Turquoise, Dark Blue, Orange, and Light Purple.
2
Place the missing color
AFTER
Every block holds all nine colors. Eight are already here, so the empty cell must get the missing one: Dark Green. Place it. Rows and columns work the same way.

Key Insight
Full houses appear all game long, not just at the end. Each bubble you place brings its row, its column, and its block closer to full. After each move, check all three. One of them may have only one cell left.
