1) Normal Sudoku

• Place the digits 1 through 9 once each in every row, column, and box.

2) Arrows

• 2.1) The digits along an arrow sum to the digit(s) in the circle.
• 2.2) Two circles have 3 digits.
• 2.2.1) These 3 digits form 6 two-digit numbers.
• 2.2.2) Each two digit number has a corresponding arrow. The number is to be read in the direction of the arrow. For example, if R4C4 is a 5 and R3C3 is a 2, the digits on the arrow that starts in R2C2 and continues in Box 1 will sum to 52. The arrow that starts on R5C5 will sum to 25.

3) Kropki pairs

• 3.1) Two adjacent cells that share a white dot have digits that are consecutive.
• Not all white dots have been given.
• 3.2) Two adjacent cells that share a black dot have digits that are in a ratio of 1 to 2.
• Not all black dots have been given.

• The digit in the grey cell with the four inward facing arrows must be smaller than the 4 orthogonally adjacent cells.
