SudokuPad (conv.): sudokupad.app/...
Masyu: Draw a non-intersecting loop that travels orthogonally through the centers of some cells, passing through every pearl. The loop must turn on black pearls and travel straight through the cells on both sides. The loop must go straight through white pearls, and turn in at least one of the cells on either side.
Cages are clones (ie, they each contain the same pattern of loop segments), counting rotations or reflections as the same.

Penpa+: tinyurl.com/38...
SudokuPad (conv.): sudokupad.app/...

SudokuPad: tinyurl.com/yw...
-Each row, column, and 9-cell bold outlined region must contain all the digits 1-9 exactly once each.

"Quot Estis in Convivio" by Chilly
SudokuPad: sudokupad.app/...
Normal 6x6 Sudoku rules apply.
Digits may not repeat on either of the marked diagonals.
Digits in a cage must sum to the cage total in the top left of the cage.
Digits on an arrow must sum to the digit in the attached circle.
Inequality: A greater than symbol separating two cells points to the lower digit.
"Entropic Pointers" by Jay Dyer
SudokuPad: tinyurl.com/2p...
Normal 6x6 sudoku rules apply.
Each set of three adjacent cells along a line must contain one digit from each set {1,2}, {3,4} and {5,6}.
All cells act as box-indexers: If the digit in cell n of box i is j, then the digit in cell n of box j is i. For example, if R1C3 is a 4, R3C6 is a 1.
"Parallel Microcosms" by Andrewsarchus
SudokuPad: tinyurl.com/42...
Normal Sudoku rules apply.
Arrows: digits on arrow must sum to the digit in the bulb.
Thermos: digits must strictly increase from the bulb end.
