Duality 8: Dual Duel by Chilly
Normal sudoku rules apply.
The lines are simultaneously between lines and entropic lines. The digits on a line must lie strictly between the digits on its end points (between). Also, any set of three sequential cells along a line must contain a low digit (1-3), a medium digit (4-6), and a high digit (7-9) (entropic). Digits may repeat on a line, if allowed by other rules.
Clues outside the grid indicate the sum of the digits between the 1 and the 9 in the corresponding row or column.
Digits separated by a white dot must be consecutive. Not all white dots are given.

Duality 9: Sumthing Yummy by Derektionary
Normal sudoku rules apply. Numbers outside the grid are sandwich clues AND x-sums clues. So, each number gives the sum of the digits strictly between the 1 and 9 in their respective row or column. Also, each number gives the sum of the first X digits in their row/column where X is the first digit that appears in the row/column from the direction of the clue.
