This puzzle combines two perennial favorites - Sudoku and dominoes.
You are given a set of dominoes with numbers 1 through 9, excluding doubles.
Your goal is to fit them into the grid so that every row, column, and heavily outlined subsection contains each digit from 1 to 9 exactly once.
To start you off, we've shown the single numbers 1 through 9 in circles, and we've already placed several dominoes.
Can you do the rest?
