4:40 "Tachyons and Black Holes" by heliopolix
SudokuPad: https://tinyurl.com/2p9y6rp2
Normal sudoku rules apply.
Place nine black holes and nine white holes in cells throughout the grid, such that there is a black hole and a white hole in each row, column, and box (no cell can have both). Each digit appears on exactly one black hole and exactly one white hole. White holes are doublers (digits have double value) and black holes are voids (digits have zero value) for little killers and killer cages.
Tachyon killer cage clues are marked with a dashed outline. Digits may not repeat in a cage (double 1 and plain 2 may be in the same cage). Digits in the cage sum to the total in the top left. Any cage must contain the same number of black and white holes (the number may be zero).
Tachyon little killer clues are marked with a value and an arrow. Digits along the indicated diagonal direction sum to the total given in the clue, starting from the cell closest to the arrow. When a little killer enters a black hole, it teleports to the white hole with the same digit and continues to sum along the indicated diagonal direction (the sum includes the black and white hole). Any little killer must travel to the same number of black and white holes (the number may be zero).
Singularity sandwich clues are marked with a value and no arrow. Digits between the black and white holes in the indicated row or column sum to the given total.
1:26:18 "Double or Sum-thing" by Josh Johnson
SudokuPad: https://bit.ly/jjsdko-doublesumthing-ctc
Almost normal Sudoku rules: Place the digits 0-9 so that each row, column, and box contains each digit exactly once.
Kropki (no negative constraint): The value of cells separated by a black dot have a 1:2 ratio. The value of cells separated by a white dot have a difference of 1.
Doubler cells: Every row, column, and box contains exactly one doubler cell. Each digit from 0-9 is doubled exactly once. The value of the cell is doubled, for the purpose of Kropki clues.
Sum-thing cells: One cell in every row, column, and box is a 'sum-thing' cell, containg two digits. The value of a sum-thing cell is sum of the two digits in the cell.
A cell may be both a doubler and a sum-thing cell. In this case, the value is double the sum of the two digits in the cell. For example, the value of a a doubled 'sum-thing' containing a 3 & 5 has a value of 16.
