1. Boost, by AllesUgo

Normal sudoku rules apply (fill each row, column, and 3x3 box with the digits 1-9 once each), and all clues are standard.
Palindromes: gray lines are palindromes, which contain the same sequence of digits in either direction.
Quadruple circles: a digit inside a white circle appears in one of the four cells surrounding that circle (if a digit repeats in a circle, it appears in two of the surrounding cells).
Very rough difficulty estimate: 3/10
