Here is a puzzle of ones and zeros (and modified cells!) to celebrate zetamath's 100th stream. Enjoy!

Rules:

Normal Sudoku: Place the digits 1 to 9 in every row, column, and 3x3 box.

1-0-0 Lines:

• Every cell containing the digit 1 has two cells that extend from it—either horizontally or vertically—to form a straight line of three cells. The 1 is always on one end of its line.
• The two extended cells (the non-1 cells) modify their digits so that each has a value of 0.
• Different lines cannot extend into the same cell, cross, or overlap, and lines cannot extend off the grid.
• Note: only the two extended cells have a value of 0—the 1s are not modified and thus have a value of 1.

Killer Cages:

• Digits in cages sum to the total in the top left corner.
• Digits in cages (modified or not) cannot repeat, but a cage may contain multiple modified cells.
