Normal 6x6 Sudoku rules apply and all variants are standard.

6x6 Sudoku: Place the digits 1-6 once each in every row, column and box.

Arrows: Digits along an arrow sum to the number in the connected circle. Digits may repeat along an arrow if allowed by other rules.

Kropki: Digits separated by a black dot are in a 2:1 ratio (one number is double the other). Digits separated by a white dot much be consecutive. Not all dots are necessarily given.
