Full House: Fill the Last Empty Cell
Also called the last free cell. It is the first technique most players learn.
When a row, column, or block has only one empty cell, the missing color goes there.
1
Find a block with one cell left
BEFORE
This block has eight bubbles and one empty cell. The colors here are Red, Yellow, Dark Purple, Light Green, Turquoise, Dark Blue, Orange, and Light Purple.
2
Place the missing color
AFTER
Every block needs all nine colors. Dark Green is the only one missing, so place it in the empty cell. Rows and columns work the same way.

Key Insight
Full houses show up all game long, not just at the end. After each bubble you place, check its row, column, and block. One of them may have only one cell left.
