Normal sudoku rules apply.
Cageless Yin Yang: Shade some cells such that all shaded cells are orthogonally connected, all unshaded cells are orthogonally connected, and no 2x2 cluster of cells is entirely shaded or unshaded. Cells in a cage do not count as shaded or unshaded.
Secret Summit: Digits orthogonally along shaded cells must be ascending or descending, with 1 and 9 reversing the direction. Digits along unshaded cells must do the same.
Vision Arrows: A digit on an arrow indicates the length of the uninterrupted run of cells immediately beyond the arrow, in the arrow's direction, that belong to the same group of shaded/unshaded cells as the arrow cell.
Thermometers: Cells on a thermometer are either all shaded or all unshaded. Digits along a thermometer increase from the bulb.
Killer Cages: Digits in a cage sum to the number in the top-left of the cage.
