Here’s an older puzzle of mine, the first time I was exploring Modifier Cells. I knew I wanted to combine Doublers and Between Lines, which proved harder than expected. This is the version I ended up most satisfied with, with an unusual amount of given digits. I hope you’ll enjoy!

Rules:

• Sudoku: Fill all rows, columns and marked 3x3 regions with the digits 1-9 without any repeats.
• Doublers: There are 9 Doubler cells in the grid, one in every row, column and region. Every Doubler contains a unique digit.
• Values: The value of a Doubler cell is twice the digit in the cell. The value of a non-Doubler cell is its digit.
• Between Lines: Values on a line must be strictly greater than one of the attached bulbs' value and strictly smaller than the other's.
