Sum Assembly Required
(Published on 6. October 2025, 01:20 by Killer Joe)
Hello!
• Standard Sudoku rules apply: each row, column, and 3×3 box must contain the digits 1–9 exactly once.
• Each cage has a two-digit total to be placed by the solver inside the cage. Place the tens digit in the leftmost cell of the topmost row of the cage, then write the total from left to right. If the cage shape doesn’t allow a left-to-right placement, write the digits from top to bottom instead.
• If the total consists of two identical digits (e.g., 22, 33, 44), write only a single digit.
• Digits may repeat within a cage, provided standard Sudoku rules are not broken.
• Digits along an arrow sum to the digit in the attached circle.
Have fun!
Solution code: Row 9, first 6 digits

Really cool puzzle! I really loved the interactions of the cage sum rules. It seemed very hard at first, but when you start thinking about what is possible in cages, you realize how quickly you can narrow things down. Thanks for sharing!
