Play on SudokuPad!
Normal sudoku rules apply.
Summit Lines: Digits along a blue line are ascending or descending, with 1 and 9 reversing the ascension/descension. Every possible sequence along a blue line must obey this rule.
Secret Summits: There are exactly two blue lines on the grid, which are mostly hidden. All visible blue line pieces on the grid contain a tip of a blue line; all tips are visible. No blue line travels through an entire 2x2 cluster of cells. Blue lines must travel orthogonally, and can branch out. Every digit in the grid is on a blue line except for digits in a cage.
White Dots: Cells separated by a white dot contain separate blue lines. Digits separated by a white dot are consecutive.
Thermometers: A thermometer shares cells with only one blue line. Digits along a thermometer increase from the bulb.
Killer Cages: Digits in a cage sum to the number in the top left of the cage (and are not on a blue line).
