Normal sudoku rules apply. Maximum: cells with a square that has arrows pointing outwards have a digit greater than the 4 adjacent cells. Minimum: cells with a square that has arrows pointing inwards have a digit smaller than the 4 adjacent cells. Even: grey squares must contain an even digit. Odd: grey circles must contain an odd digit. Killer cages: digits in a killer cage must sum to the number in the top left corner and cannot repeat. Palindromes: digits on a grey line read the same forwards and backwards. Skyscrapers: skyscrapers are visible when looking from that direction. Digits in the grid represent the heights of the skyscrapers. Taller skyscrapers block the view of any smaller skyscrapers behind them. Clues outside of the grid give the number of skyscrapers visible from that point in that row or column.
