This puzzle variant is different than the more traditional one which shows the sum of pairs of diagonally opposite cells. This one is actually more similar to a killer sudoku, but the "cages" can overlap and can have repeated digits.

By the way, I made a few other versions of this puzzle before I realized that the clues can be arranged symmetrically.

Rules:

• Normal sudoku rules apply.
• Digits surrounding a circle must add up to the given total (they can repeat if other rules allow).
