This is the third nabner puzzle in a small series. I had a lot of fun combining the nabner property with outside clues. Have fun and leave a comment if you like it.

• Nabner Arrows
• Nabner meets Schrödinger
• Nabner Outside Clues

Rules:

Standard sudoku rules apply: The digits 1 through 9 appear in every row, column, and box.

Nabner Sandwich sum: Clues ABOVE the grid indicate the sum of the digits between 1 and 9 in that column. No two digits between 1 and 9 (those two digits excluded) can be consecutive.

Nabner X-Sums: Clues to the LEFT and the RIGHT of the grid give the sum of the first X numbers placed in the corresponding row or column, where X is digit in the cell next to the X-sum clue. No two digits along this sum can be consecutive.

(Standard) Numbered Rooms: The clue BELOW the grid indicates the digit which has to be placed in the Nth cell in the corresponding direction, where N is the digit placed in the first cell in that direction.
